        <![CDATA[Over the last twelve months a trend towards implementing flash drives as a new tier of memory has emerged. Driven by the lower cost of flash when compared to RAM plus the growing realization that not all of an application's data requires the performance boost that flash provides, more organizations are looking to deploy flash as a new tier of memory. But as more solid state drive (SSD) manufacturers try to fit their SSDs into this new SSD use case, the trick for users is to figure out which product architecture is the best fit.<br /><br />The impetus behind adopting flash as a new memory tier is being driven by four main factors:<br /><br /><ul><li>DRAM costs about <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.storagesearch.com%2Fssd-ram-flash%2520pricing.html" target="_blank">9X </a>more than flash</li><li>SSDs cost roughly <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.computerworld.com%2Fs%2Farticle%2F9134468%2FReview_Hard_disk_vs._solid_state_drive_is_an_SSD_worth_the_money_" target="_blank">10x</a> more than HDDs</li><li>Only 5 - 20% of application data is sufficiently active to benefit from flash's performance</li><li>Deploying a mix of DRAM, SSD and SATA HDDs can be more economical and perform better than a mix of DRAM with FC and SATA HDDs</li></ul>It is for these reasons that implementing SSDs as a new tier of memory is resonating with users for business and technical reasons. However what is not so obvious is which SSD architecture is the right choice for use as a memory tier since all SSDs are not architected in the same way.<br />&nbsp;<br />SSD architectures can be broadly classified in two ways:<br /><br /><ul><li>Storage controller approach</li><li>Memory controller approach</li></ul>The <i><b>storage controller approach implements SSDs so they look and function like HDDs.</b></i> While I have previously <a href="http://sponsored.dciginc.com/2010/03/ssds-hidden-data-integrityflaw.html">illustrated</a> some of the risks associated with implementing flash in this way, the two main problems that result are <i><b>added costs</b></i> in the construction of the SSD and new risks resulting from the <i><b>soft errors</b></i> that can occur within the SSD.<br /><br />The extra costs result from manufacturers embedding processors, DRAM and firmware into the SSD. These are needed to make flash look like an HDD to an operating system. <br /><br />Adding these extra components also introduces the possibility that soft errors can occur since many SSD products lack sufficient intelligence to detect soft errors should they occur and then correct them if they do. What few SSDs do possess this level of sophistication to detect and correct these soft errors carry a much higher price tag.<br /><br />In addition, two other concerns emerge when using SSDs that are based upon the storage controller technique in this context of a new memory tier.<br /><br /><ul><li><i><b>They are significantly slower than native flash.</b></i> SSDs that are implemented using the storage controller architecture require that data traverse its internal controllers. This can force the data to take as many as nine (9) additional hops before it gets to its final destination. Data translations also have to occur between each layer as it moves from ATA or SCSI protocols to flash and back again. </li></ul><ul><li><i><b>Users must make an unpleasant RAID configuration decision.</b></i> Users must account for the possibility that an SSD may fail so they have to select an appropriate RAID configuration to protect the data on that SSD. In the case of SSD, no RAID option is particularly attractive. Any RAID implementation will require the purchase of more SSDs and each RAID configurations comes with trade-offs. RAID 0 sacrifices reliability and redundancy; RAID 1 sacrifices capacity; and, RAID 5 introduces an additional performance hit. </li></ul><i><b>Introducing SSDs that use a storage controller as a memory tier is feasible but using them in this manner is akin to trying to put a square peg in a round hole. </b></i>It is for this reason that SSDs with a memory controller architecture are much more well suited for this emerging use case as a memory tier.<br /><br />SSD products such as the <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.fusionio.com%2F" target="_blank">Fusion-io</a> <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.fusionio.com%2Fproducts%2Fiodrive%2F" target="_blank">ioDrive</a> that use a memory controller take steps to minimize concerns around the upfront costs of SSDs and the soft errors that can result from their implementation. <br /><br />But what makes an SSD solution that uses a memory controller architecture appealing for use as a new tier of memory is that it takes three (3) steps to lower costs, increase performance and decrease risk.<br /><br /><ul><li><i><b>First, Fusion-io eliminates the need to manage an SSD like an HDD.</b></i> Flash is not longer put into a box and configured to look like an HDD to the operating system. Instead Fusion-io collapses flash onto a PCI-Express card that is inserted directly into a PCI slot on the server backplane.</li></ul><ul><li><i><b>Second, Fusion-io removes the need to configure SSDs in a RAID configuration by creating a flash array that has redundancy.</b></i> In this configuration, it has multiple redundant flash chips that can dynamically replace any flash chip that becomes defective without requiring a user to replace the PCI-Express card.</li></ul><ul><li><i><b>Third, it performs address translations the same way that virtual memory address translations are performed which is probably its most important characteristic.</b></i> This technique removes the need for the numerous embedded address translations that SSDs that use a storage controller design require while expediting processing since only one translation needs to occur.</li></ul>These steps contribute to making SSDs that use a memory controller architecture particularly well suited to act as this new memory tier because they do more than just act like virtual memory. T<i><b>hey actually behave as if they are virtual memory since there is no intermediary bus or hierarchy of controllers that the data first has to traverse.</b></i> Using this technique data can flow directly onto a <i><b>Fusion-io ioDrive</b></i> since it <i><b>is specifically architected to act like DRAM and communicate in flash, the same language that DRAM uses</b></i>.<br />&nbsp;<br />Leveraging virtual memory to complement DRAM has long been a technique used to accelerate application performance. But this <i><b>new option</b></i> to <i><b>introduce SSDs that communicate in the same language as DRAM</b></i> has a <i><b>dramatic</b></i> and <i><b>positive impact on how applications perform </b></i>while forcing organizations to rethink how they will architect their storage infrastructures going forward. <br /><br />To successfully execute on this vision and implement SSDs as a new memory tier dictates that organizations chose the right SSD architecture if they hope to optimize SSDs deployed in this manner. To do so, they must select SSDs that are architected to function as memory controllers, not storage controllers. It is for these reasons that organizations that want to leverage SSD as a new memory tier should look to the Fusion-io ioDrive as it is exactly these types of problems that it was architected and designed to solve. ]]>

        <![CDATA[It's easy for those new to <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.vmware.com%2F" target="_blank">VMware</a>, or even for those who have used VMware for awhile, to assume that all VMware backup solutions provide similar functionality. While it might be true to say that all of these solutions protect VMs, their similarities in many cases end there. Among their differences, two of the largest focus on how they manage VMware backups and the ensuing archives that are created which is where software like <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.vizioncore.com%2F" target="_blank">Vizioncore</a>'s vRanger Pro stands out.<br /><br /><font style="font-size: 1.25em;"><b>VMware Backup Job Management</b></font><br /><br />The management of backup jobs in VMware environments bears little to no resemblance to what they look like in the physical world. In the physical world, backup administrators have the opportunity to document what applications are running on individual physical machines, what the application's peak hours of operations are and how much of a physical machine's resources the application consumes and when. Based upon that information, they can schedule backup jobs accordingly.<br />&nbsp;<br />In the virtual world, that luxury is gone.&nbsp; Multiple VMs now reside on a single physical machine that share the same underlying network and storage resources. So now to effectively manage them calls for the backup administrator to know which VMs host which applications and the application's peak hours of operation. Further, backup administrators also need to account for how all of these resources in the virtual environment are being used, when they are being used and under what conditions.<br /><br />Server virtualization environments with more than one physical host add to the management complexity.&nbsp; Simply retrieving a list of alphanumeric VM names from each VMware host or from the vCenter console and then scheduling backup jobs does not take into account all of these variables. <br /><br />This is where vRanger Pro differentiates itself. It queries the environment and obtains details such as how many VMDK files are associated with each VMware ESX or vSphere host, what networked storage protocols are being used and how storage is shared between VMs. Then once it obtains that information, backup administrators can set up parameters within it that define when and how the resources within it are used. <br /><br /><a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.vizioncore.com%2Fproducts%2FvRangerPro%2Findex.php" target="_blank">vRanger Pro</a> eliminates the complexity of manually orchestrating these activities. <i><b>By automating the monitoring and collection of data of the available resources within the VMware environment, it can dynamically schedule <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fvcommunity.vizioncore.com%2Fdataprotection%2Fvrangerpro%2Fb%2Fbackup20%2Farchive%2F2010%2F04%2F30%2Fhow-does-the-snapshot-work-for-image-based-protection.aspx" target="_blank">VM backup jobs</a> according to the availability of resources in the physical environment.</b></i> It now does so without negatively impacting other backup jobs or production applications and without the need for backup administrators to constantly monitor and intervene to ensure backup jobs complete successfully. <i>(More information about how vRanger Pro does this is available <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fvcommunity.vizioncore.com%2F" target="_blank">here</a>.)</i><br /><br />Yet vRanger Pro's ability to monitor resources in the virtual environment and then dynamically schedule backup jobs according to the availability of these resources is only one part of the equation to successfully protecting VMs. Equally important is how it creates and manages the resulting backup archives.<br /><br /><font style="font-size: 1.25em;"><b>Backup Archive Management</b></font><br /><br />The manner in which backup archives are created can contribute to how many concurrent backup jobs can take place at one time. Further, more organizations are looking to bring these archives under the management of their main backup software to meet their broader disaster recovery (DR) initiatives and regulatory compliance requirements. <br /><br />To facilitate these emerging user demands, vRanger Pro manages its archives in such a way that it can run multiple backup jobs at the same time while still granting a third party backup software access to these archives that they can be effectively managed.&nbsp; vRanger Pro does the following to accomplish these tasks:<br /><br /><ul><li><i><b>Creates and manages multiple independent archive files.</b></i> vRanger Pro creates multiple, independent archive files that are each associated with a specific VM so that multiple backup jobs each with their own data stream can concurrently take place. This enables vRanger Pro to dynamically schedule VM backups. As resources in the virtual environment become available it can immediately run the backup job with each job having a Save Point within that individual archive file. </li></ul><ul><li><i><b>Use "human readable" names.</b></i> vRanger Pro names each VM backup archive so that as the archive is backed up by the main backup software, naming conventions remain "human readable". This enables backup administrators to identify by simply looking at the name of the archive file which backup archive belongs to what VM. Further, they can ascertain the date and time that the backup archive was created and if the archive file is a full, incremental or differential.</li></ul><ul><li><i><b>No modifications to backup archives.</b></i> When the main backup software does incremental and differential backups, it looks for and detects image level block changes in archive files so if they have changed, it backs them up again. This is why vRanger Pro leaves archives unmodified and daily creates a new backup file. This minimizes the amount of data that the main backup software will have to protect as well as the amount of tape capacity that it will eventually need to store these archives.</li></ul><blockquote><i><b>Modifying the backup archives also creates compliance concerns as it brings into question the authenticity of the data in the backup archive.</b></i> Recent court rulings cite the inability to preserve data subject to litigation holds as a reason to issue sanctions against companies. <i><b>Since vRanger Pro does not modify backup archives, it does not leave organizations exposed to these types of rulings.</b></i><br /></blockquote><ul><li><i><b>A portable archive file for each VM.</b></i> Each archive file created by vRanger Pro has its own Save Point.This makes it possible for organizations to port the archive file to either a USB thumb drive or a tape cartridge so any archive file may be taken to another location and the individual VM associated with that archive file restored or recovered. </li></ul><font style="font-size: 1.25em;"><b>vRanger Pro: A Winner in the World of VMware Data Protection<br /></b></font><br />There are differences between backup solutions intended for the protection of VMware environments but those differences are not always easily discerned. Yet it is those unseen features such as the monitoring of available resources in the virtual environment, the dynamic scheduling of backup jobs based upon that information and then the creation and management of backup archives that separate the winners from the losers in the world of VMware data protection.<br /><br /><i><b>vRanger Pro's ability to deliver on these features is a major reason why it is a winner in this space. </b></i>vRanger Pro monitors the virtual environment for available resources so backup jobs can be dynamically scheduled. It creates independent archive files that it associated with specific VMs to help facilitate the scheduling of multiple concurrent backup jobs. It assigns a unique, recognizable and understandable name to each archive file to facilitate recoveries by either vRanger Pro or third party backup software products. Finally, it creates a Save Point within each archive file so that it remains portable and suitable for offsite recoveries.<br /><br />How well organizations incorporate and manage VMware's server virtualization technology will separate winners from the losers in the months and years to come. So as they look to optimize the management of virtualized environment, it is imperative that they select a VMware backup solution that provides the seen and unseen features that will both successfully backup and recover this virtual environment and complement whatever backup strategy they already have in place.&nbsp; vRanger Pro delivers on these specific needs that virtualized environments possess.<br /> ]]>

        <![CDATA[When organizations think of running their mission critical applications on "highly available, highly reliable" storage systems, they almost always think of FC SANs.&nbsp; It is time for that mindset to change. The now mature and proven availability and reliability features of <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.nfsv4.org%2F" target="_blank">NFS v4</a> coupled with organizations who can testify to their use of NFS v4 in mission critical environments are creating new use cases for deploying more cost effective, easier to manage NAS storage solutions.<br /><br /><b>NFS's High Availability and Reliability Struggles</b><br /><br />NFS's prior struggles with delivering enterprise class availability and reliability are in part attributable to how previous versions of NFS (pre-NFS v4) managed the "state" of files.&nbsp; While NFS's file management is suitable for single servers, new NFS issues emerge when applications are deployed on clustered pairs of servers.<br />&nbsp;<br />One issue has to do with an NFS imposed limitation that prevents the second server in a two server cluster from accessing a file on the first if that first server should fail. In pre-v4 versions of NFS, the file server places a lock on the file that the first server is accessing to protect the integrity of the file.&nbsp; This works well until one gets into a clustered server configuration.<br /><br />At that point the file lock becomes a problem when/if the first server fails. Once it fails, NFS continues to maintain its lock on the file since NFS is unaware that the first server has become unavailable. So when the application starts processing on the second server, it cannot access the file until the existing NFS file lock is released. Unlocking this file generally requires intervention on the part of a system administrator.<br /><br />Failovers are not the only point where NFS's file management limitations rear its head. It also surfaces during routine application operation. <br /><br />For instance, if an application client moves from the first server to the second, the application client may no longer be able to access the file since the first server still owns the rights to the file. <br /><br />Pre-v4 versions of NFS do permit the introduction of third party software that can manage this switchover of an application from the first to second server. However this additional software makes creating highly available and reliable NFS configurations more costly and complex to implement and manage.<br /><br /><b>NFS v4 Brings High Availability and Reliability to NAS</b><br /><br />NFS v4 provides for improved options for stable client fail-over that did not exist in prior versions. <br /><br />Arguably <i><b>one of its biggest improvements is its client-server lease management feature that changes how it handles file management</b></i>. Whereas pre-v4 versions of NFS placed a permanent lock on a file while it was being accessed, the default setting in NFS v4 requires clients to "check-in" every 45 seconds or else the file lock is released. <br /><br />The primary advantage this provides is ease of application fail over in NFS environments as it eliminates the need for administrators to get involved with releasing file locks should the first server fail.&nbsp; Now the application can fail over to the second server and access the files that it needs in 45 seconds since NFS v4 automatically releases the file locks in that time.<br /><br /><i><b>The client-server lease management in NFS v4 also comes into play when an application moves from the first active server to another that is also active</b></i>.&nbsp; NFS v4 supports several file sharing modes that can control and manage file access by other application clients. <br /><br />Leveraging these different modes, <i><b>application clients can specify the mode in which specific files are accessed</b></i>.&nbsp; So if an application client does move to another server, prior to moving it can use NFS v4 to set file permissions so it can continue to have uninterrupted access to the files without waiting for the default NFS v4 time out that would release the first server's file lock. <br /><br />These functional improvements to NFS v4 permit organizations to deploy NAS storage solutions in highly available and reliable environments or use these applications in conjunction with NAS storage solutions that are already implemented.<br /><br />However a big part of the reason that organizations have not yet deployed NAS solutions with NFS v4 is that users still remain unconvinced of its maturity. Convincing users to move their mission critical applications to NAS is nearly impossible if proponents of NFS v4 cannot provide other customers who can testify that NFS v4 works as promised when deployed in this type of environment.<br /><br /><b>NetApp Puts Its Money Where Its Mouth Is<br /><br /></b>It is this specific customer concern that <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.netapp.com%2Fus%2F" target="_blank">NetApp</a> sought to address. NetApp made the decision to deploy its own <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.netapp.com%2Fus%2Ftechnology%2Funified-storage%2F" target="_blank">Unified Storage Architecture</a> with NFS v4 to support its internal mission critical TIBCO Enterprise Service Bus (<a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.tibco.com%2Fsoftware%2Fenterprise-service-bus%2Fdefault.jsp" target="_blank">ESB</a>) application. <br /><br />NetApp uses the TIBCO ESB to broker messages between its different billing, shipping and order taking applications. During the day, these applications generate millions of messages that the TIBCO ESB application server processes and then stores to a file.<br /><br />NetApp had already once tried running <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.tibco.com%2F" target="_blank">TIBCO</a> ESB on NFS v3. However the feature set in NFS v3 did not meet TIBCO ESB's availability and performance requirements so NetApp opted to assign shared LUNs to the TIBCO ESB servers and install a host-based clustered file system on those servers to meet the TIBCO ESB's availability and reliability requirements.<br /><br />This all changed in December 2007. It was at that point that <i><b>NetApp determined that its implementation of NFS v4 on its NAS storage solutions had sufficiently matured</b></i> and were ready for use with TIBCO ESB. <br /><br />Now over two years later NetApp's move of TIBCO ESB onto its NFS v4 supported platform has paid off. NetApp is still running TIBCO ESB on its Unified Storage Architecture and, because NetApp put its money where its mouth is, more of NetApp clients are evaluating implementing NFS v4 in their own environments. <br /><br />In this case, NetApp is acting as a reference as to why prospective customers should use an NFS v4 enabled NAS solution. Among the benefits NetApp cites, it no longer needs to buy, install and manage host-based clustered file systems on the TIBCO ESB servers. Further, NetApp is achieving greater storage management efficiency as it can now manage more of its storage in the same way.<br /><br /><b>Deploying NAS with NFS v4 is an Act of Reason not a Leap of Faith</b><br /><br />NFS v4 specifications were released in 2003 so they are not new standards by any stretch and have been widely adopted and put in place by many NAS providers. But the lag time between the initial announcement of the NFS v4 specifications and the time it has taken to implement its features have been substantial. <br /><br />This lag time surely contributes to why users might feel like NFS v4 is a "new" specification that cannot yet be "trusted" in mission critical environments. <br /><br />However NetApp recognized that it could not ask end users to take a leap of faith that it was not first willing to take. So by running the TIBCO ESB application on an NFS v4 enabled NAS solution for over two years, NetApp helps to break through this logjam of both a lack of reference customer accounts and the benefits that NFS v4 can provide.<br /><br />NetApp's own example demonstrates the NFS v4 is ready for prime time and that prospective customers do not need to a leap of faith in order to run mission critical applications on NFS v4. Rather, this example should provide other companies that currently use host-based clustered file systems to support any of their mission critical applications ample reason to take a more careful look at the "new" high availability and reliability features found within NFS v4 and how they can leverage them to achieve the same reduced costs and improved operational efficiency that NetApp has already achieved. ]]>

However a careful analysis of the total cost of ownership between <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.rdxstorage.com%2Frdx-technology%2F" target="_blank">RDX</a> and <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.ultrium.com%2Ftechnology%2Fdefault.php%3Fsection%3D0" target="_blank">LTO-3</a> will show that an RDX disk-based backup solution can be more affordable than a comparably configured LTO-3 tape solution.(<i>To understand and learn more about RDX Solutions see <a title="blocked::http://www.rdxstorage.com/" href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.rdxstorage.com%2F" target="_blank">www.rdxstorage.com</a></i>.)<br /><br />Most IT administrators of SMB environments recognize the benefits associated with using disk as a backup target. Faster backups, backup success rates that climb to over 99% and increased confidence that they can restore data are just some of disk's benefits. But these arguments alone are not always enough to convince cost conscious managers who may look solely at the <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.provantage.com%2Fimation-27127%257E73MDS2V2.htm" target="_blank">$250</a> price tag of a 500 GB RDX cartridge.<br /><br />So to justify the use of RDX media they need a solid business case to support the argument of using disk in lieu of tape. To do this, all of the costs associated with obtaining and then supporting a RDX solution must be compared and contrasted with a comparable LTO-3 tape solution.<br /><br /><font style="font-size: 1.25em;"><b>Where Disk and Tape Cross</b></font><br /><br />Both RDX disk and LTO-3 tape media have associated acquisition costs and there is a point where these costs cross. To pinpoint where, I looked at the acquisition costs of these media on the websites of two online retailers, <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.cdw.com%2F" target="_blank">CDW</a> and <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.provantage.com%2F" target="_blank">Provantage</a>.<br /><br /><a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.cdw.com%2Fshop%2Fproducts%2Fdefault.aspx%3FEDC%3D743450" target="_blank">$30</a> for an LTO-3 tape cartridge is commonly cited as the primary reason to select tape. But what SMBs can overlook is the high upfront cost of an LTO-3 tape drive. While its price varies, it will cost anywhere from <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.cdw.com%2Fshop%2Fproducts%2Fdefault.aspx%3FEDC%3D1539592" target="_blank">$1200</a> for a half-height (HH) model to <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.cdw.com%2Fshop%2Fproducts%2Fdefault.aspx%3FEDC%3D1152158" target="_blank">$1800</a> for a full size LTO-3 tape drive. <br /><br />RDX almost completely removes this cost from the equation. A RDX docking station costs about <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.provantage.com%2Ftandberg-data-8550-rdx%257E7TANM00W.htm" target="_blank">$150</a> (it is listed as $390 when I wrote this blog but that price includes a 500 GB cartridge) which is a fraction of the cost of the LTO-3 tape drive.<br /><br />So when adding up the costs to obtain comparable amounts of capacity, RDX can actually be less expensive than tape until an SMB needs more than 2.5 TBs of capacity (when the price of HH LTO-3 tape drive is factored in) or more than 4 TBs of capacity when a full size LTO-3 tape drive is needed.<br /><font style="font-size: 1em;"><b><br />RDX versus Half-Height LTO-3 Tape Drive (Total Capacity - 2.5 TBs)</b></font><br /><br />RDX Docking Station&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; $ 150&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; HH LTO-3 Tape Drive&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; $ 1200<br /><u>5 - 500 GB RDX Cartridges</u> &nbsp;&nbsp; &nbsp;<u>$1250</u>&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<u>6 - LTO-3 400 GB Cartridges&nbsp;</u>&nbsp; &nbsp;<u>$&nbsp;&nbsp;&nbsp; 180<br /><br /></u><b>Total Cost&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; $1400&nbsp;&nbsp; &nbsp; &nbsp; Total Cost &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; $&nbsp; 1380</b><br /><b><br />RDX versus Full Size LTO-3 Tape Drive (Total Protected Capacity - 4 TBs)</b><br /><br />RDX Docking Station&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; $ &nbsp; 150&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; LTO-3 Tape Drive&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $ 1800<br /><u>8 - 500 GB RDX Cartridges &nbsp;&nbsp; &nbsp;$ 2000</u>&nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; <u>10 - LTO-3 400 GB Cartridges&nbsp;&nbsp; &nbsp;$&nbsp;&nbsp; 300</u><br /><br /><b>Total Cost&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; $ 2150&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; Total Cost&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $ 2100</b><br /><br />So the argument that LTO-3 tape media is cheaper than RDX disk media is only true when the 2.5 and 4 TB thresholds of capacity are crossed. It is at this point that LTO-3 can become more cost effective since LTO-3 cartridges scale more economically than RDX cartridges.<br /><br />This scaling argument is relevant since SMBs have weekly and monthly media rotations and need these additional cartridges for these backups. This media rotation would again appear to favor LTO-3 tape over RDX but it fails to take into consideration another benefit of RDX.<br /><font style="font-size: 1.25em;"><b><br />Big or Small, RDX can use them all</b></font><br /><i><b><br />A clear advantage that RDX provides is the freedom to use any generation of RDX cartridge regardless of its capacity.</b></i>&nbsp; RDX <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.rdxstorage.com%2FTech-Specs-Final.pdf" target="_blank">cartridges</a> are available in 80, 160, 320, 500 and 640 GB sizes with 750 GB capacities soon to become available. This is what gives RDX an edge over LTO-3 tape: any size cartridges may be used in an RDX docking station.<br /><br />This is not the case with LTO-3 technology. While LTO-3 tape drives can read from prior generations of LTO tape technology (LTO-1 and LTO-2),<i><b> they can only write to LTO-3 tape cartridges</b></i>. So regardless if an organization has 20 GBs or 360 GBs of data to backup, they have to purchase a 400 GB LTO-3 cartridge.<br /><br /><i><b>This freedom to use any RDX media may bend the cost advantage back to RDX.</b></i> If an organization only has 100 GB of data to backup, they can purchase a smaller 160 GB RDX media at around $115/cartridge. So now the cost of a year's supply of 23 RDX cartridges (5 for daily backups, 6 for weekly backup and12 for monthly backups) plus an RDX docking station is $2795.&nbsp; Further, as larger RDX disk sizes become available, the price for smaller capacity cartridges tends to drop.<br /><br />In contrast, the cost for a competing LTO-3 tape solution with a full size LTO-3 tape drive and 23 cartridges is around $2490. Now the two are about on par when one looks at a full year of media rotation. However there is yet one more factor that favors RDX media over LTO-3.<br /><br /><font style="font-size: 1.25em;"><b>The Nine Lives of RDX</b></font><br /><br /><i><b>RDX cartridges have a longer life than tape.</b></i> Unlike tape cartridges, which may need to be replaced after 10 - 20 uses, there is no such limitation on RDX cartridges.<br />&nbsp; <br /><i><b>RDX cartridges can be re-used almost indefinitely and almost never need to be replaced. </b></i>They come with a 5 year warranty so if an RDX cartridge fails for some reason, the cartridge can be replaced at no cost.<br />&nbsp;<br />Finally, <i><b>the shelf life of an RDX disk cartridge is every bit as long as tape.</b></i> A recent <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.prostorsystems.com%2FNews%2FPress-Releases%2FPress-Releases-2007%2FIndependent_Lab_Certifies_30-Year_Archive_Life_for_RDX_Removable_Disk_Cartridge_Solution.aspx" target="_blank">study</a> reveals that an RDX cartridge has a shelf life of 30 years (equal to that of tape) and the data on RDX media can be more easily restored later on since they are not dependent on specific generations of tape drive models like LTO is.<br /><br />So let's tie this back to the total cost of ownership. Daily backup tape cartridges will need to be replaced about once a quarter and weekly backup tape cartridges about once a year plus new tape cartridges are needed every month for the monthly backup. <br />&nbsp;<br />In contrast, daily and weekly RDX cartridges may never need to be replaced and an appropriately sized new RDX cartridge is purchased as needed for the monthly backup. This longevity of the RDX cartridge further helps in its cost justification.<br /><br /><font style="font-size: 1.25em;"><b>When RDX Media is the Right Business Choice</b></font><br /><br /><i><b>Looking solely at the cost of individual tape cartridges is failing to recognize tape's true cost. </b></i>While no one disputes that the per cartridge cost for LTO-3 is substantially less than an RDX cartridge, there is also no denying that the upfront cost for an LTO-3 tape drive is 10x the cost of an RDX docking station.<br />&nbsp;<br />So the real determinant of whether to choose an RDX or LTO-3 cartridge likely comes down to how much data a SMB needs to protect. If the total amount of data that it needs to protect on is no more than 2.5 - 4 TBs, RDX wins. Further, the use case for RDX only gets stronger for those SMBs that have less data to protect since they may use smaller, less expensive RDX cartridges.<br /><br />So those SMBs that find themselves with less than 4 TBs of data may well find that RDX media are more than just the preferred choice from a technical and operational perspective. RDX now becomes the right choice from a business perspective as well. ]]>

        <![CDATA[Next generation networked storage systems are adding solid state drives
(SSDs) at an accelerated pace as a means to deliver dramatic
performance gains for mission-critical, performance sensitive
applications. To accomplish this, SSDs are being constructed to look
and act like hard disk drives (HDDs) and while this seems sensible,
this creates the possibility for data integrity issues to emerge. <br /><br />To offset this, enterprise SSD providers take a number of steps to account for these issues. <a href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.fusionio.com%2F" target="_blank">Fusion-io</a>
is unique in that it has come up with a method that mitigates these
problems while lowering the cost and complexity of fixing them.<br /><i><b><br />It Looks Like an HDD But ...</b></i><br /><br />On
the surface, the process of making an SSD look like an HDD appears
straightforward. As part of accelerating the rate of the adoption of
SSDs, SSDs are made to look and act like HDDs so they are easily
recognized by existing server operating systems and/or storage system
firmware.<br />&nbsp;<br />In this respect, the emulation of SSDs is going
pretty well. Users and/or manufacturers can plug an SSD device into a
slot on a PC, server or storage system such that it looks just like an
HDD to the OS and is managed as such.<br />&nbsp;<br />But to make an SSD look
and act like an HDD, data translations and re-mappings need to occur
that call for the utilization of embedded CPUs and DRAM on the SSD.
These additional components increase the cost of SSDs as well as raise
the number of failure points in places that could <a href="http://sponsored.dciginc.com/2010/02/detection-of-soft-errors.html">compromise data integrity</a>.<br />&nbsp;<br />Specifically, <i><b>these embedded components create the possibility that soft errors can occur without detection and correction</b></i>. This can result in questions regarding the integrity of data stored or retrieved from the SSD.<br /><i><b><font style="font-size: 1.25em;"><br />Where Soft Errors Occur</font></b></i><br /><br />Soft errors can occur at one of two times within SSD devices.<br /><br /><ul><li>First,
during writes, data sent to the SSD device is in a format that is
suitable for storing on an HDD, not an SSD. To store it, the SSD uses
its embedded CPU and DRAM to convert the data to a format that flash
recognizes and then maps and stores the data to a location on the SSD
device.</li><li>On reads, the opposite must occur. Since the
application expects the data back in a recognizable format, the SSD
device must again leverage its embedded CPU and DRAM to do a lookup of
the data on the SSD so that it can be re-mapped back to a format that
is recognizable by the application.</li></ul>This process of remapping
the data from FC and/or SCSI format to flash and then back again is
where the possibility for soft errors is introduced. Since DRAM is used
as part of the process, the SSD's calculations are susceptible to
errors. While infrequent, soft errors can and do occur as they are
caused by external forces such as cosmic radiation. What is important
to note is that there does not need to be a flaw in the hardware or an
error in the firmware for these soft errors to occur.<br /><br /><b><i><font style="font-size: 1.25em;">Cost is Why Soft Errors are Left Undetected</i></b></font><br /><br />The
possibility of cosmic radiation impacting data integrity is overlooked
because today's computer systems generally have built-in error
correction code (ECC) that can detect and correct soft errors caused by
this type of anomaly. However, <i><b>most DRAM used in SSDs do NOT support ECC and most do not even have parity</b></i>. As such, they can neither check nor correct these soft errors when data is remapped. <i><b>The danger this presents is that the SSD cannot DETECT when a soft error occurs</b></i>.<br />&nbsp;<br />Unfortunately <i><b>most consumer grade SSDs do not use DRAM that supports ECC or parity for one simple reason: ECC DRAM is more expensive</b></i>. As a result, most SSD devices that have a FC, SAS or SATA interface do not provide this needed layer of data protection.<br />&nbsp;<br />This
explains why in enterprise environments where data integrity is a
necessity that enterprises must deploy SSDs that detect and correct
these soft errors. But to do so, they must pay extra.<br />&nbsp;<br />However
this technique is only one way to avoid soft errors. There is another
way that costs less, ensures that the SSD appears as an HDD to the
operating system and can detect and correct soft errors.<br /><br /><i><b>Solid-State Data Integrity with Speed but without Cost</b></i><br /><br />Fusion-io
has developed a method to accomplish all three of these objectives:
reducing costs, avoiding soft errors and appearing as an HDD. To do
this, Fusion-io places its ioDrive directly on a server's PCI-Express
bus.<br />&nbsp; <br />In this configuration, the server's CPU can directly interface with the <a href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.fusionio.com%2Fproducts%2Fiodrive%2F" target="_blank">ioDrive</a>
using direct memory access (DMA) via the server's PCI-Express bus. This
design eliminates the need for a storage controller in the server as
well as embedded CPUs on its ioDrive since the HDD translation does not
occur on the ioDrive.<br />&nbsp;<br />However in order for the ioDrive to
appear as an HDD, Fusion-io installs a driver on the host that does the
remapping. This driver serves two important purposes.<br />&nbsp;<br />First, by
moving the translation layer to the host, its driver functions much
like much like a page table does on today's operating systems: it
translates virtual memory addresses to physical memory addresses. <br /><br />Fusion-io's
host software driver works in a similar manner. When the CPU asks for
some logical block address, it goes through Fusion-io's software
driver. This driver translates it to where it is physically on the
NAND. Since it is physically addressed directly as memory, this
contributes to Fusion-io's high speeds.<br /><br />The other important
purpose that putting this software driver on the host serves is that
the translation is protected since the driver is in the server's
memory. This allows it to take advantage of the native ECC and parity
protection found on these servers. Then as an added layer of security,
Fusion-io validates its results by double checking the data after it is
remapped to ensure it is all properly labeled once it is on the media. <br /><br /><i><b>The Fusion ioDrive: A Fundamentally Better Approach</b></i><br /><br />Forcing SSDs to look like HDDs is done because it seems like the simplest and easiest way to accelerate the adoption of SSDs.&nbsp; <i>But SSDs are not HDDS! </i>They
are flash and trying to make flash cost-effectively and safely look and
act like an HDD while still preserving the integrity of the data is not
easily done.<br /><br />To do this, other SSDs take six steps to do the
data translation and remapping. This adds costs, slows SSD's speed and
introduces risks. Fusion-io's approach of putting its ioDrive directly
into the server enables organizations to more safely and
cost-effectively harness the many advantages that SSDs provides. <br /><br />But
in the process of placing its ioDrive inside the server, Fusion-io does
more than just accelerate application performance, lower SSD's costs or
preserve the integrity of data. Fusion-io also puts organizations on a
path of re-thinking not just how they should leverage SSDs in their
infrastructure but what is the appropriate role and placement of SSDS
and networked storage within their data center environment going
forward. ]]>

        <![CDATA[Enterprise users are facing some tough choices right now as solid state drives (SSDs) begin to proliferate in the datacenter. Not only must they sort through the performance benefits and documented drawbacks of typical SSDs, they must also determine which SSDs are suitable for use in mission critical applications. But as they do, new evidence is emerging that an SSD's classification as "enterprise ready" is not determined by an SSD's use of "MLC" or "SLC" but rather if it possesses the ability to detect and correct soft errors as they occur.<br /><font style="font-size: 1em;"><b><br /><font style="font-size: 1.25em;">Historical "Consumer" versus "Enterprise" SSD Classification</font></b></font><br /><br />According to some <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.storagesearch.com%2Fssd-top10.html" target="_blank">estimates</a>, there are well over 100 OEMs of SSD storage systems on the market today with SSDs finding its way into more storage systems that typically receive the "enterprise" label. As they do, an aging criteria that differentiated between "consumer" and "enterprise" grade SSDs is based on whether or not the SSD is a multi level cell (MLC) or single level cell (SLC) design.<br /><br />MLC SSDs are most often associated with "consumer" grade. The knock on MLC SSDs is that they lack the performance and reliability of SLC SSDs. SLC SSDs experience wear-out after approximately 100,000 program/erase cycles while MLC SSDs experience wear-out after 10,000 or less cycles. The upside of MLC SSDs is that they can reach higher capacities (over <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.maximumpc.com%2Farticle%2Freviews%2Fsamsung_256gb_mlc_ssd" target="_blank">200 GB</a>) and are available at a lower price point because so many manufacturers are starting to produce them for desktops and laptops. <br /><br />Conversely, SLC SSDs are the ones finding their way into enterprise storage systems. While the storage capacity of SLC SSDs is lower and they have a higher price than MLC SSDs, they support faster write speeds and have higher cell endurance so they have lower error rates. Since SLC SSDs do a better job of mitigating the possibility of data corruption, they are finding their way into the enterprise space since, at this level, data integrity arguably is more important than performance.<br /><br /><font style="font-size: 1.25em;"><b>Flash is Unreliable</b></font><br /><br />However at their core both MLC and SLC SSDs are flash drives, not hard disk drives (HDDs). SSD manufacturers have taken steps to make SSDs appear as HDDs to operating systems and applications but this action of making a flash drive look like an HDD is where the potential - and likelihood - for soft errors (an error in a computer's memory system that changes an instruction in a program or data value) to occur.<br /><br />To make flash look like block storage requires a tremendous amount of processing power. Embedded microprocessors and DRAM are placed on the individual SSD devices that handle the task of making the SSD device appear as an HDD to the operating system and applications by handling the exchange of data between the application and the underlying SSD media. <br /><br />While manufacturers are taking the appropriate steps to protect data once it is stored on the SSD to ensure that the data is preserved and does not become corrupted over time, this newly created process of handing off the data and retrieving it from the flash media is when soft errors can and do occur.<br /><font style="font-size: 1.25em;"><b><br />The "Unexamined" SSD Data Integrity Risk</b></font><br /><br />This new compute process within the SSD devices that makes flash appear as an HDD is creating different data integrity risks that, to date, have gone largely unexamined as to the impact that it can have on data. <br /><br />In brief, the specific problem that these new processes create is that it is still uncommon for most SSD devices to put enough sophistication into this process to even detect errors should they occur, much less do error correction. Because they are not looking for soft errors much less taking any steps to correct them should they occur, there is a small but distinct possibility that during the metadata handling that occurs with the processor instruction stream, something could go awry and the wrong piece of data could be stored or retrieved from the underlying flash media.<br /><br />This soft error could later show up in financial applications displaying inaccurate financial information or healthcare software retrieving inaccurate information about a patient. The danger here is that because there is no error checking going on during the conversion process, invalid data could be presented as valid data due to the lack of data integrity checking that is occurring at this point in the process.<br /><br /><font style="font-size: 1.25em;"><b>The True "Consumer" versus "Enterprise" SSD Differentiator</b></font><br /><br />These anomalies in system behavior - and how they are addressed - are exactly what differentiates consumer from enterprise SSD solutions. In enterprise environments SSDs are more likely to be used for applications with high transaction rates. This increases the likelihood of this soft error anomaly occurring from "improbable" to "highly likely" so these applications demand SSD solutions that deliver performance while also taking these data integrity issues into account.<br /><br />The increased frequency of these errors was confirmed in a recent <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.cs.toronto.edu%2F%257Ebianca%2Fpapers%2Fsigmetrics09.pdf" target="_blank">study</a> completed by the University of Toronto. The researchers found that DRAM error rates are "orders of magnitude higher than previously reported, with 25,000 to 70,000 errors per billion device hours per Mbit and more than 8% of DIMMs affected by errors per year." While the researchers found that memory errors are dominated by hard rather than soft errors, any system using memory without support for error correction and detection can lead to a memory error resulting in a machine crash or applications using corrupted data. <br /><br />Because of the possibility that soft errors can occur, enterprises need SSD solutions that account for this behavior by detecting and correcting soft errors. Indeed, this ability to detect and prevent such anomalies from occurring is becoming the true differentiator between consumer and enterprise grade SSD solutions. <br /><font style="font-size: 1.25em;"><b><br />Fusion-io Takes the Appropriate Steps to Detect and Correct Soft Errors in SSDs</b></font><br /><br />Enterprise SSD solutions will take the appropriate the steps to protect both the memory and CPU instruction stream from being corrupted <i>prior to</i> the data being stored to the SSD and then when it is retrieved. So any enterprise organization that is looking at SSD and has concerns about the integrity of its data stored on SSD needs a solution that mitigates the possibility of soft errors ever occurring.<br /><br />Enterprise organizations are right to have a fair amount of skepticism about the appropriate role that SSDs should play in their data centers in light of their high cost and documented problems. This latest issue of how soft errors can occur within the SSD device itself is only one more reason that enterprise users should remain skeptical. <br /><br />However the emergence of SSD solutions such as the Fusion-io <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.fusionio.com%2Fproducts%2Fiodrive%2F" target="_blank">ioDrive</a> is one such product that takes into account the possibility of the occurrence of these soft errors and takes steps to prevent them from occurring. In an upcoming blog, I will take a look at two different techniques that currently exist for addressing this issue and why <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.fusionio.com%2F" target="_blank">Fusion-io</a> has selected the approach it has for addressing soft errors. ]]>

        <![CDATA[Server virtualization is clearly becoming the end game for all size data centers. But as they virtualize their physical servers using Microsoft Windows Server 2008, new challenges emerge that range from managing each virtual machine's storage to effectively scaling up the number of the virtual machines (VMs) on each physical machine. This is where Virsto One, the newly introduced storage virtualization software from <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.virsto.com%2F" target="_blank">Virsto Software</a>, comes into play.<br /><br />The benefits of virtualizing physical servers are now well-known. Better utilization of physical server resources like CPU and memory; smaller server footprints in data centers; and, lower power consumption are just part of the payback that organizations expect and get when they implement server virtualization.<br /><br />However as organizations virtualize multiple applications and consolidate them onto a single physical server, the issues associated with managing this configuration are not as well understood. Specifically, organizations are bound to encounter some or all of the following problems:<br /><br /><ul><li><i><b>I/O blending.</b></i> One of the lesser understood problems of virtualizing physical servers is that<i><b> just because the server is virtualized does not mean its operating system understands it is virtualized.</b></i> Operating systems still presume that they have their own dedicated storage resources so they have limited or no ability to prioritize read and write I/Os.</li></ul><blockquote>This lack of prioritization creates a problem for the underlying hypervisor.&nbsp; It is forced to mix the read and write I/O of all of its guest operating system together regardless of the nature of the application on the VM. This condition, known as I/O blending, <i><b>results in the I/O of less critical applications receiving the same priority as more critical applications</b></i>. This can negatively impact application performance.<br /></blockquote><ul><li><i><b>I/O performance degradation.</b></i> This condition of blending I/Os contributes to an overall degradation in the performance of each VM. While virtualizing a single application results in little or no performance degradation, no one virtualizes just one application. The intent is always to consolidate and virtualize as many application servers as possible onto one physical server. </li></ul><blockquote>This is where the problem emerges. One recent <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fitknowledgeexchange.techtarget.com%2Fserver-farm%2Fvirtual-machines-per-server-a-viable-metric-for-hardware-selection%2F" target="_blank">survey</a> revealed that 61% of respondents run less than 10 VMs on a physical machine while only 5% run more than 25.&nbsp; The reason for the disparity is that as more application servers are virtualized, especially high performance applications, the more performance degrades. This inhibits how many VMs an organization may place on a single physical server and potentially limits the cost benefits that server virtualization may deliver. <br /></blockquote><ul><li><i><b>Server virtualization sprawl.</b></i> The two aforementioned issues become especially insidious since many administrators are not aware they exist until after they start to experience them. Due to the ease in which server virtualization makes it possible to create a new VM, even as the number of physical servers drop, the number of VM instances on the physical servers increase. One shop, after implementing server virtualization, <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fsearchservervirtualization.techtarget.com%2Fnews%2Farticle%2F0%2C289142%2Csid94_gci1209313%2C00.html" target="_blank">reported</a> a drop in the number of physical machines by 20% but a subsequent 150% increase in the number VM instances.</li></ul><ul><li><i><b>Storage over provisioning</b></i>. The ease in which VMs can be created can easily result in storage over provisioning. A "golden image" VM clone is typically created to facilitate the rapid creation of new VMs going forward. The only problem with this approach is that a fixed amount of disk is associated with each "golden image" clone even though each new VM may need only a small percentage of the storage capacity associated with that clone. This method results in storage being assigned that goes unused while also depleting the pool of available storage capacity. </li></ul>These issues are what today's <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.virsto.com%2Fnews%2Fpress%2Fvirsto-introduces-first-hypervisor-based-storage-virtualization-software%2F" target="_blank">release</a> of Virsto One is designed to address. Virsto One is storage virtualization software that installs in the parent partition of Microsoft Hyper-V. <br />What makes Virsto One unique is its ability to provide enterprise class storage features at a fraction of the cost of previously existing solutions. To facilitate ease of management, it leverages standard Microsoft management methods such as <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fsearchservervirtualization.techtarget.com%2Fnews%2Farticle%2F0%2C289142%2Csid94_gci1209313%2C00.html" target="_blank">WMI</a>, <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fmsdn.microsoft.com%2Fen-us%2Flibrary%2Fbb756943.aspx" target="_blank">MMC</a> and <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Ftechnet.microsoft.com%2Fen-us%2Fvirtualserver%2Fbb676673.aspx" target="_blank">VHD</a>.<br /><br />Virsto One uses techniques similar to high performance relational databases by journaling I/Os from individual machines and then de-staging them to their permanent storage location.&nbsp; This technique of sequentially writing redundant I/Os addresses many of the performance and storage problems associated with VM environments plus it offers new options for users to grow and better manage their VM environment going forward. For example, it:<br /><br /><ul><li><i><b>Eliminates the performance impact of I/O blending.&nbsp;</b></i> Using Virsto One, write I/Os occur more quickly. Preliminary results from early adopters indicate that there is almost no drop-off in application performance even as more VMs are added to the physical server.</li><li><i><b>Facilitates the cost-effective introduction of high performance disk such as FC, SAS or even solid state drives (SSDs) into virtualized environments. </b></i>Since Virsto One needs only small amount of high performance disk, it facilitates the introduction of higher tiers of disk such as FC, SAS and SSD that will only enhance Virsto One's performance benefits. </li><li><i><b>Supports VM consolidation and scale-up.</b></i> Organizations can now confidently add more VMs to a physical server and even potentially support multiple high performance applications on the same physical server as Virsto One can mitigate the I/O bottlenecks that previously prevented them from doing so.</li><li><i><b>Lowers storage costs.</b></i> Virsto One lowers storage costs in two ways. First, it thinly provisions an unlimited number of VM-optimized, space-efficient and high performance "golden image" clones that only consume as much storage capacity as the VM actually needs. Second, many of the performance benefits that Virsto One delivers are a result of the I/O journaling discussed above. This permits organizations to use lower performing, more economical disk for permanent data storage since the data can be optimized for future reads by Virsto One as it is stored.</li></ul>While Virsto One is currently available only for Microsoft Hyper-V environments, Virsto indicates that it intends to extend these benefits to other server virtualization platforms in the near future. In the meantime, Virsto dramatically changes the playing field for Microsoft Hyper-V as it opens the door for organizations to scale the number of VMs on a single physical server to a much higher level than they may have previously considered. Further, because of how it can accelerate write I/O, organizations can more seriously examine putting multiple high performance application servers on a single physical machine.<br />&nbsp;<br />Virtual server storage and performance management still give many organizations pause when it comes time to deciding which applications to virtualize or if they should grow their existing VM installation. Virsto One starts to take these concerns off the table as it helps to remove these barriers.<br /><br />Using Virsto One, organizations sitting on the fence can more confidently start down the path to server virtualization. Likewise, those already on this road can use Virsto One to become even more aggressive in taking advantage of the benefits that server virtualization offers with Microsoft Hyper-V. In this regards, Virsto One dramatically improves server virtualization's immediate and long term value proposition while simultaneously improving the manageability of both performance and storage on VMs. <br />]]>

        <![CDATA[Virtualization, consolidation and servers are becoming inextricably linked in the minds of mid-sized organizations as they look to reduce data center footprints and energy consumption while increasing server hardware utilization. Yet what can get overlooked during the consolidation and virtualization of their Windows applications is the development of a corresponding storage strategy. This is where the specifics on what is needed to deliver on an appropriate storage solution for this environment become a necessity.<br /><br />Executing on a successful application and server consolidation and virtualization strategy for mid-sized organizations now calls for networked storage. As far back as September 2006, one storage provider <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fsearchstorage.techtarget.com%2FmagazineFeature%2F0%2C296894%2Csid5_gci1258982_mem1%2C00.html" target="_blank">found</a> that <i><b>SAN attach rates for server virtualization environments ran at approximately 70% in enterprise environments</b></i>. At that time, that provider forecast that as commodity Ethernet infrastructure became more commonplace, network storage attach rates would climb even higher.<br /><br />Fast forward to today and 1 Gb Ethernet networks are almost ubiquitous among mid-sized organizations. Toss in the fact that analyst groups like <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.forrester.com%2Frb%2Fresearch" target="_blank">Forrester Research</a> <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fesj.com%2FArticles%2F2009%2F07%2F14%2FServer-Virtualization.aspx%3FPage%3D1" target="_blank">anticipate</a> that <i><b>mid-sized organizations will virtualize another 25% of their server instances by 2010</b></i> so it becomes a near certainty that their use of external storage will increase.<br />&nbsp;<br />However it is also a distinct possibility that these same organizations have not quantified the key attributes that their network storage solutions need to possess in order to support their newly virtualized application servers.<br /><br /><i><b>Consolidated networked storage solutions must account for new availability, performance and scalability requirements that server consolidation and virtualization creates</b></i>. Microsoft Exchange, SharePoint, SQL Server and backup servers are just some of the applications that will be virtualized while organizations will also look to consolidate file and print servers onto a centralized, networked attached storage (NAS) device.<br /><br />Meeting these various needs calls for storage systems that possess the following three characteristics: <br /><i><b><br />High Availability<br /><br /></b></i>The consolidation and virtualization of Windows applications onto just a few physical servers - or even onto one server - means mid-sized organizations are putting all of their "eggs in one basket" so they have new needs for high availability for both their servers and their storage.<br /><br />To compensate for this heightened risk on the physical server, server hardware often includes dual power supplies and network cards. In addition, new software features such as Live Migration found in the release of Microsoft Windows 2008 Hyper-V R2 operating system or VMware vMotion™ enable high availability through the dynamic application failovers from one physical server to another.<br /><br /><i><b>These same principles of high availability need to carry over into the storage hardware that is used by these virtualized applications</b></i>. For example, a storage system such as the NetApp <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.netapp.com%2Fus%2Fproducts%2Fstorage-systems%2Ffas3100%2F" target="_blank">FAS3100</a> Series possesses all of the redundancy features found in server hardware as well as features such as dual active controllers and hot-swappable components such as controllers, fans and power supplies that can be replaced without requiring system downtime.<br /><br />The FAS3100 also allows data replication as part of its solution. Using this software, users can configure the FAS3100 to replicate data locally in the form of its <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.netapp.com%2Fus%2Fproducts%2Fplatform-os%2Fsnapshot.html" target="_blank">Snapshot</a> feature or remotely using its <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.netapp.com%2Fus%2Fproducts%2Fprotection-software%2Fsnapmirror.html" target="_blank">SnapMirror</a> feature. Mid-sized organizations can even take advantage of the FAS3100's <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.netapp.com%2Fus%2Fproducts%2Fprotection-software%2Fmetrocluster.html" target="_blank">MetroCluster</a> feature which can continuously replicate data to another remote FAS3100 for continuous offsite application availability.<br /><br /><i><b>Data Protection</b></i><br /><br />A growing concern with the virtualization of applications is how to best protect the data of these applications. Virtualized applications must now share their underlying physical server's hardware resources with other virtualized applications.<br />&nbsp;<br />The sharing of hardware resources is often taken into account before applications are consolidated but the network, memory and performance resources that each application's backup software requires can be overlooked. This can result in server bottlenecks during off-peak hours as the backup software on each virtual machine (VM) contends for these limited server hardware resources.<br /><br /><i><b>Off-host backups in the form of snapshots that occur on the storage system are now seen as preferential to running traditional backups on each application's VM</b></i>. By using features such as the FAS3100 Snapshot, organizations can create near-instantaneous backups of individual VMs and associated data without incurring any performance penalty on the host physical server.<br /><br />Once created, these snapshots can be then used in a couple of ways. They can serve as a primary source for recovering application data since administrators can directly access and recover date from these snapshots. Alternatively, they can act as a source for the application data that backup software running on another server can access and they copy the data off to disk or tape.<br /><br /><i><b>Scalability and Flexibility</b></i><br /><br />It is no secret that data growth continues even in today's continued tough economic environment. However server virtualization makes it even easier for organizations to create new VMs that require more data storage. This can aggravate problems on the storage side since organizations may buy a system that cannot scale, cannot support multiple tiers of storage, or both.<br />&nbsp;<br />The dynamics of this environment makes it difficult to plan and account for every detail going forward which makes it a necessity to identify a storage system that:<br /><br /><ul><li><i><b>Provides flexible options for growth.</b></i> Organizations should have options to add more capacity, new software features or even upgrade the entire storage system as the availability, capacity and performance demands of the virtualized server environment change. <br /></li></ul><blockquote>NetApp FAS storage systems are notable in that they all use the same underlying operating system (<a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.netapp.com%2Fus%2Fproducts%2Fplatform-os%2F" target="_blank">Data ONTAP</a>) so its advanced software features such as <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.netapp.com%2Fus%2Fproducts%2Fplatform-os%2Fflexvol.html" target="_blank">FlexVol</a> (thin provisioning) and <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.netapp.com%2Fus%2Fproducts%2Fplatform-os%2Fdedupe.html" target="_blank">deduplication</a>, are available on any NetApp model from entry level <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.netapp.com%2Fus%2Fproducts%2Fstorage-systems%2Ffas2000%2F" target="_blank">FAS2000</a> Series to high end <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.netapp.com%2Fus%2Fproducts%2Fstorage-systems%2Ffas6000%2F" target="_blank">FAS6000</a> Series. NetApp also gives organizations the flexibility to scale performance or storage capacity so organizations can theoretically start out with a FAS2000 and grow it to a FAS6000 without ever needing to do a data migration.</blockquote><ul><li><i><b>Minimizes impact to environment during upgrades.</b></i> Virtualized applications decrease the tolerance for downtime for any reason including storage system upgrades and NetApp provides this type of availability for higher end FAS models. For instance, if organizations start out with a FAS2020 and need to upgrade to a FAS2040, it can do an in place. upgrade of the existing system without incurring any significant application downtime.</li></ul><ul><li><i><b>Minimizes learning curve.</b></i> IT staffing levels are remaining flat or even declining so the interface and commands that organizations use to manage the storage system should ideally remain the same as it scales to larger, more robust systems. <br /></li></ul><blockquote>In this respect, <i><b>NetApp is unparalleled among storage system providers as it uses a common management interface across all of its platforms</b></i> so once users learn its commands, they can use the same commands on any of NetApp platforms without needing to relearn them.</blockquote><ul><li><i><b>Block and file storage interfaces.</b></i> Organizations are consolidating multiple types of applications - database servers, Exchange servers as well as file and print servers. As they do so, some applications belong on server virtualization platforms such as VMware vSphere or Microsoft Hyper-V while others more appropriately belong on storage systems that support NAS. In this regards, <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.netapp.com%2Fus%2F" target="_blank">NetApp</a> offers both block (SAN-FC, iSCSI, FCoE) and file (NAS-CIFS, NFS) interfaces so organizations can consolidate onto a single unified storage platform for simplified administration.</li></ul>The adoption of server virtualization is well under way in mid-sized organizations and forecast to gain momentum in 2010 for a host of reasons. But as its adoption accelerates, mid-sized organizations must consider the entire scope of their virtualized environment which must include storage.<br /><br />Selecting an appropriate networked storage system that will host the data of virtualized applications is now critical to the overall success of implementing virtualization. It is for these reasons that storage system characteristics such as high availability, data protection and scalability and flexibility play such an important role in determining how successfully applications will perform and are managed after they are virtualized.<br />&nbsp;<br />So when one finds features like deduplication, high availability, replication, snapshots and thin provisioning on a storage platform, one can have a high degree of confidence that it offers these three characteristics that mid-sized organizations now need for their virtualized Windows environments. This is why platforms such as the NetApp Unified Storage Architecture are so well suited for virtualized environments and have become critical to delivering on all of the requirements that mid-sized organizations are sure to encounter both initially and in the future as they start down the virtualization path. ]]>

        <![CDATA[People may come and go but applications live forever. Well, not exactly, but that mindset leads to the application retirement problems that many organizations face today. Often applications remain intact and running on corporate networks long after their useful life is over but gracefully shutting them down is no simple matter. However the recently released <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.solix.com%2Fsolix_exapps_appliance.htm" target="_blank">Solix ExAPPS</a> appliance provides organizations a new option for retiring these applications while alleviating the uncertainty normally associated with such decisions.<br /><br />Application functionality, architecture, or business rules often change over time that can render an application obsolete that leaves an organization's application portfolio less than optimized. In a research paper, <i><a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.gartner.com%2FDisplayDocument%3Fdoc_cd%3D167629" target="_blank">Plan Legacy Application Retirements Carefully</a></i>, Jim Duggan, a Research VP with Gartner, makes the following observation, "On average, 10% of the applications in an un-optimized portfolio are candidates for retirement. An additional one-third can require migration or rationalization." <br /><br />In an era of economic downturn, where companies want to squeeze costs and do more with less, all sizes of companies, from SMBs to large corporations, are recognizing the value of application retirement. This is done as much to reduce costs and simplify the IT infrastructure as it is done to eliminate the need to migrate or virtualize seldom or minimally used applications. <br /><br />Considering that many enterprise organizations have numerous applications spread across many server platforms with numerous database servers on the backend, the value of decommissioning these application servers quickly becomes evident. However application retirements go beyond just the hardware and software costs. Maintaining and managing the infrastructures needed to support legacy applications takes expertise, often specialists. <br /><br />Aggravating the situation, as an organization continues to run old applications on legacy hardware or out-dated software versions, the available amount of expertise in the within an organization or marketplace continually diminishes. This increases the risk of losing all expertise associated with an application; running applications that are unsupported or require high-maintenance; and, having data in-house with no one being able to access or interpret data in a knowledgeable fashion. <br /><br />So while the cost benefits of retiring applications may be clear, the risks associated with application retirement can be vague. Consider:<br /><br /><ul><li><i><b>Organizations lack expertise in the application retirement process</b></i>. This results in an inability to zero in on which applications should be retired</li><li><i><b>Organizations cannot quantify which underlying application data needs to be retained</b></i>. This creates apprehension and risk when considered against the backdrop of compliance requirements and different federal and state regulations.</li><li><i><b>Budgets are already tight. Obtaining funding for additional resources can be difficult</b></i>, especially when those resources are high-paid consultants and the applications scheduled for retirement often are already included as line items in the organization's budget.</li></ul>But probably the biggest question that organizations face when deciding to retire an application is, "<i><b>What will happen to the data?</b></i>" The data may be needed for compliance and legal reasons but who else uses or accesses the data. Sometimes there are no records as to when the last time the data was accessed, who accessed it and for what purpose. Further, no one wants to say they were the one who deleted the data only to find out later that it is needed by executive management.<br /><br />Therefore before any solution is introduced that facilitates application retirement, it must satisfy the following criteria:<br /><br /><ul><li><i><b>The application context of legacy data must be preserved</b></i>. Not only must objects, columns, and attributes be preserved but an understanding of how an application's logic interprets codes and the relationships between data so the application data still makes sense should it need to be retrieved and referenced in the future. </li><li><i><b>Data is stored in an accessible format</b></i>. Regardless of data format for an application, data must be stored in a compatible format. If a legacy application uses a backend database that contains binary large objects (BLOBs) then the storage repository for retired applications should be able to accommodate and efficiently store these types of objects as well.</li><li><i><b>Store all legacy data stored in a single location</b></i>. This makes it simpler and more efficient to find and retrieve later on should the requirement emerge.</li><li><i><b>All legacy applications should be considered to have unique data reporting requirements</b></i>. These requirements should be fully supported by any BI tools that are put in place after the application retirement.</li><li><i><b>An open or standard access method should be used</b></i>. While it is difficult to predict data access methods in the future, storing data in formats that are considered open today increase the likelihood that the data can be retrieved at some point in the future.</li></ul>It is these issues that the new Solix ExAPPS addresses. Recognizing this new corporate need for a solution that automates application retirement while preserving application data integrity, Solix ExAPPS is a pre-built, pre-configured, and pre-tested appliance that can be plugged directly into the corporate network for the single purpose of application retirement. <br /><br />Organizations only need to use a Web browser to point the Solix ExAPPS at an identified target application's data using a Web browser. Once it sees the application, ExAPPS begins the process of migrating all of the application's data, including its objects, reports, and the context of how the application data is used and referenced, to the Solix ExAPPS secured repository in an immutable form. This process guarantees data can not be modified and remains safe to meet compliance requirements. <br /><br />Since this is a fully automated process, it a repeatable and eliminates the manual, ad hoc nature of past application retirement attempts that relied heavily upon consultants, system integrators and third parties utilities and migration tools. <br /><br />Once an application is retired and the data moved over to the Solix ExAPPS appliance, business users or IT can query the ExAPPS appliance and report on the legacy data using standard enterprise reporting tools. While the data is stored in a proprietary database (the Solix Secure Archive), it is accessed using a standard SQL engine so standard database query methods will work. <br /><br />Depending on how the Solix ExAPPS is utilized, organizations may see even further savings. ExAPPS compresses legacy data by up to 90% and a single Solix ExAPPS Appliance can replace multiple physical servers, applications and storage in the data center thereby significantly reducing operating budgets and increasing operational efficiencies.<br /><br />The benefits of shutting down aging or unused applications are easy to see but as anyone knows who has ever been asked to turn such an application off - you hate to be the one responsible for pushing the button only to have someone request the application data later on. The Solix ExAPPS takes these concerns about application retirement off the table. Using the Solix ExAPPS appliance, organization can quickly and easily deploy a solution that enables them to achieve their goal of cost-effectively application retirement.<br />]]>

        <![CDATA[<p>Putting a disaster recovery plan in place is a task that every company pays lip service to but when push comes to shove, how many companies - regardless of their size - actually take the initiative and follow the plan all the way through? The answer is far too few. Whether it is an unspoken belief that a disaster will never really happen or the costs are simply too high, most companies find it nearly impossible to move their DR plan beyond the discussion stage. </p>
<p>In recent blog entries I've discussed the advantages of AmeriVault's new ReStartIT-VDR service and how easily it allows companies to execute on their plans to put a DR plan in place. So the question is why aren't companies moving faster? Most likely because companies have failed to take a hard look at their current tape based backup environment and come to grips that they have no assurance whatsoever that they can recover their business applications using tape. </p>
<p>I am not anti-tape but business recovery requirements have fundamentally changed. Despite this fact, companies persist in using tape when the recovery requirements of today's business applications are not hours, days or weeks but seconds, minutes or at most hours. These requirements completely obliterate whatever rationale companies might have for wanting to stick with tape as their primary means of recovery but still they do so.</p>
<p>This does not even take into account all of the headaches associated with managing the tape media itself. Tape media breaks and wears down, the tape cartridge and tape drive format may be incompatible, tape rotation is difficult to manage and tapes can be lost or difficult to find. Then add in intangibles like documentation, expertise and like systems at a secondary site in order to recover the data. The irony is that the entire premise of using tape as a foundation for disaster recovery is based on a lie and the sooner companies realize this the sooner they can get off the tape merry-go-round and start to focus on making smart decisions about how to backup and recover their corporate data.</p>
<p>The beautiful thing about what AmeriVault is doing is they are making the smart decision easier for businesses to make. In essence, AmeriVault backs up and recovers your data for the same amount of money or less than you are spending now while guaranteeing it will work. From my viewpoint, you have to be crazy, stupid or looking to join the ranks of the unemployed not to listen to this message. So my recommendation is for more companies to take the blinders off and take a harder look at what AmeriVault's online backup and its accompanying <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.amerivault.com%2Freplication_services%2Fvirtual_disaster_recovery.html" target="_blank"><u><font color="#0000ff">ReStartIT-VDR</u></font></a> can offer in solving one's backup and DR problems in 2008.</p>]]>

        <![CDATA[<font size="3">
<p>Today, December 21st, marks the official launch of AmeriVault's new ReStartIT-VDR and ReStartIT-HA services. Though December 21st is primarily marked in the annals of history as the day when the Mayflower landed at Plymouth, MA, for AmeriVault in particular and small and midsize businesses (SMBs) in general, it may well serve as a point of demarcation in terms of changing how businesses can expect to restart their IT operations using AmeriVault's services should a disaster occur.</p>
<p>The spectrum of disasters that may impact a company's IT operations is vast. Though the number of natural disasters is fairly finite - blizzards, earthquakes, fires, floods, hurricanes and tornados, to name a few - there is an almost an infinite number of minor disasters that are just as disruptive to IT operations, such as broken water pipes, defective air conditioners, overloaded electrical circuits or an out of control car crashing into the side of your computer room. Any of these disasters can force a company with minimal or no warning to abruptly move and restart their IT operations at another location just to stay in business.</p>
<p>However anyone involved in corporate operations understands that the trials and tribulations involved with configuring, setting up and then managing an alternative site is no trivial task. Aside from the costs associated with setting up a disaster recovery (DR) site, other intangible factors that come into play include:</p>
<p></font><font face="Symbol" size="3">· </font><font size="3"><font style="FONT-SIZE: 1em">Who takes the lead in a DR scenario?</font></font></p>
<p><font face="Symbol" size="3">· </font><font size="3"><font style="FONT-SIZE: 1em">Who takes the lead if that person is not available?</font></font></p>
<p><font face="Symbol" size="3">· </font><font size="3"><font style="FONT-SIZE: 1em">Who is responsible for funding for the DR site?</font></font></p>
<p><font face="Symbol" size="3">· </font><font size="3"><font style="FONT-SIZE: 1em">What if there is inadequate funding to recover certain applications at the DR site?</font></font></p>
<p><font face="Symbol" size="3">· </font><font size="3"><font style="FONT-SIZE: 1em">Who tests the recovery of applications and how often?</font></font></p>
<p><font face="Symbol" size="3">· </font><font size="3"><font style="FONT-SIZE: 1em">How quickly do you need to recover your business? </font></font></p>
<p><font face="Symbol" size="3">· </font><font size="3"><font style="FONT-SIZE: 1em">Can your DR site support multiple recovery points? If not, do you need and can you afford to change your DR configuration?</font></font></p>
<p><font face="Symbol" size="3">· </font><font size="3"><font style="FONT-SIZE: 1em">What if it is a partial disaster and you only need to recover some of your applications at your DR site? Do you fail everything over or just the affected applications?</font></p>
<p>These are just some of the types of questions and scenarios that businesses need to ask and account for when building out and maintaining a separate DR site. However these questions and issues are by no means an exhaustive list. Unfortunately what too often occurs is that for any company who takes the time to thoroughly examine the issue, they will almost inevitably decide that the costs and headaches associated with building out a separate DR facility gives them no more assurance of a safe recovery than doing nothing.</p>
<p>This is why the new </font><a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.amerivault.com%2Freplication_services%2Fvirtual_disaster_recovery.html" target="_blank"><u><font color="#0000ff" size="3">ReStartIT-VDR and -HA</u></font></a><font size="3"> services from AmeriVault make so much sense for so many businesses. For about $25,000 a year, a business with 300 GB of production data can introduce a level of business continuity and application recovery that previously was available only to companies with DR budgets of millions of dollars and dedicated staff. </p>
<p>Using AmeriVault's new ReStartIT services, companies can restart their corporate applications at AmeriVault's data center while employees work from home and access their applications running at AmeriVault's site through secure Internet links. AmeriVault even offers an option where companies can take advantage of AmeriVault's partnership with Agility Recovery Solutions. Agility Recovery Solutions delivers mobile recovery trailers, replacement hardware and telecom so businesses can recover their IT operations within 48 hours. AmeriVault synchronizes data recovery for a complete data-to-desktops solution.</p>
<p>December 21st, 2007, is a day when most of us are looking forward to a few days off and celebrating Christmas with friends and family. However for those looking forward to the promise of how to better protect one's business, today's launch of AmeriVault's ReStartIT starts to deliver on those promises a few days early. </p></font>]]>

        <![CDATA[<font size="3">
<p>Over the last few years, many of the major vendors in traditional backup software and storage solutions have strayed from their well-established roots. Iron Mountain, Seagate, EMC and Symantec have all jumped into the online backup managed service pool mostly via acquisition. IBM even made a splash last week as the latest vendor to announce an acquisition of an online backup managed service provider (MSP). </p>
<p>But what does this mean for end users facing solution decisions going forward? In the past it was just a question of what tape media, tape drive and offsite records management provider to use. Now the choices are tape, disk or managed services. To address these issues, I caught up with AmeriVault's Director of Marketing, Scott Bush, to discuss this industry trend and what challenges that end users face.</p>
<p>First, Scott raised some questions where potential conflicts of interest may arise when a publicly-traded enterprise with a traditional in-house solution acquires an online backup service provider.</p>
<dir>
<dir></font><font face="Symbol" size="3">
<p>· </font><font size="3"><font face="Times New Roman">What will happen when you integrate sales efforts?</font></p></font><font face="Symbol" size="3">
<p>· </font><font size="3"><font face="Times New Roman">Are you going to receive the best solution or whatever will please shareholders the most?</font></p></font><font face="Symbol" size="3">
<p>· </font><font size="3"><font face="Times New Roman">Will technical support jump through hoops or have to conform to a process that handles tens-of-thousands of customers?</font></p></font><font face="Symbol" size="3">
<p>· </font><font size="3"><font face="Times New Roman">Will the new regime embrace the superior technology and still provide the number of personal touches that made the service great in the first place? </font></p></dir></dir>
<p>Second, in this consolidation climate, Scott feels AmeriVault's position is ideal. It maintains a highly-secure and redundant infrastructure and then adopts best-of-breed software to deliver the latest advances available such as </font><a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.amerivault.com%2Fbackup_solutions%2Fcontinuous_data_protection.html" target="_blank"><u><font color="#0000ff" size="3">continuous backup</u></font></a><font size="3"> and </font><a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.amerivault.com%2Fonline_backup%2Famerivault_av.html" target="_blank"><u><font color="#0000ff" size="3">deduplication</u></font></a><font size="3">. Being very deep and narrow in online data protection assures AmeriVault stays focused on customer needs and the number of touches needed to optimize service and facilitate disaster recoveries.</p>
<p>Scott adds that competing with these larger, public enterprises doesn't change the rules. You still have to fully fix the problem, be credible and offer a competitive price. Then it all comes down to service, where AmeriVault feels it has the edge. </p>
<p>Overall, though, Scott sees the IBM acquisition as a positive for AmeriVault. Seeing the traditional storage providers add managed, online service to their portfolio raises the visibility and awareness of online backup among customers and gives AmeriVault's business model more credibility. He feels this is the final validation that online backup is a best practice and threat to traditional in-house solutions. </p>
<p>To further differentiate but remain true to data protection, AmeriVault continues to wrap complementary services around its online backup service including </font><a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.amerivault.com%2Freplication_services%2Freplication_services.html" target="_blank"><u><font color="#0000ff" size="3">RestartIT-VDR</u></font></a><font size="3">, an economical, remote recovery solution and </font><a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.amerivault.com%2Fdata_archiving%2Famerivault_dv.html" target="_blank"><u><font color="#0000ff" size="3">AmeriVault-DV</u></font></a><font size="3">, a lifecycle and archiving service that handles older, less-accessed data. These offerings coupled with its highly available&nbsp; infrastructure and its continued independence should give AmeriVault advantages that allow them to compete with other companies who are buying their way into the business. </p></font>]]>

        <![CDATA[<p align="left">"Online backup has gone from an educational process to which vendor should I choose."</p>
<p>That's the state of online backup according to AmeriVault's CIO, Kevin Harris. In the 10 years since he and CEO Bud Stoddard founded AmeriVault, he has seen tremendous changes in customer perceptions and understanding about online backup.</p>
<p>Back then the Internet was still in its infancy and the idea of using online backup to send data over the Internet was a "scary thing" in the eyes of prospective AmeriVault clients. Harris says, "We had to prove everything including how we would backup data, how they would recover data and if it was secure and safe."</p>
<p>In 2007 these issues are largely laid to rest as most prospective customers now understand how it works. The larger problem Harris deals with now is how does AmeriVault differentiate itself? Customers can now go out to Google, do a search on online backup and get 30 pages of hits on companies that provide online backup. Since they all look the same based on Google search results, now the first question prospective clients are most likely to ask is, "What vendor should I choose?"</p>
<p>Choosing a vendor based on the lowest price is simply not enough anymore since, as Harris puts it, "online backup prices are all over the map". There are multiple criteria to consider when selecting a managed service provider and many now use the same underlying backup software to provide online backup services. In this competitive environment, Harris says one of AmeriVault's differentiators is to offer a "high touch" approach.</p>
<p>Harris points to AmeriVault's call center as one of the ways they deliver on that promise. Though businesses can contact AmeriVault by email, when they need to recover data they almost always use the phone. To make good on that promise, AmeriVault has its own people answering calls but during periods of high call volumes, AmeriVault contracts with a third party answering service to answer the overflow who immediately contact AmeriVault. 'No one is ever stuck leaving a voice message," promises Harris.</p>
<p>Providing service level agreements is the other primary way that Harris sees as an AmeriVault differentiator. AmeriVault guarantees three 9's of uptime (99.9% system availability) and response times of two hours or less on all customer calls on or off business hours. "As far as I know, we are the only managed service provider in the industry that provides these types of guarantees," says Harris. </p>
<p>As AmeriVault's CIO Harris astutely points out, "high touch" will become, if it is not already, a key to customers to selecting the right provider of online backup services for them. Google makes it easy to find scores of providers whose offerings on the surface may look very similar and provide no easy way to differentiate between providers. By wrapping "high touch" around online backup services and then stamping it with a guarantee, AmeriVault makes the choice of an online backup provider an easier one to make.</p>

        <![CDATA[<p>Businesses have come to terms that their data growth rates are climbing ever higher and generally deal with them by consistently bringing in more storage to house it. However what companies may fail to do is account for how they intend to protect this data and evolve their data protection schemes to manage this data growth. Since backup is generally not a strategic initiative for most companies, the question more companies should ask themselves is, "Is it wiser for us to outsource my backups than try to manage this function ourselves?"</p>
<p>That's the question Jeannine Gaudreau, the Manager of Network Engineering and Security at <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.darwinsuzsoft.com%2Fhomepage%2Fhome.aspx" target="_blank">Darwin Partners</a>, a Wakefield, MA, based IT Services firm asked over eight years ago. When she first assumed her role at Darwin Partners, she initially could backup all of Darwin Partner's data to a single tape. At that time her biggest concerns were simply remembering to take the backup tape offsite and buy new tapes when they expired. However as Darwin Partners grew, so did the amount of data she needed to manage and backup. </p>
<p>As she watched her company's data growth rate explode, she saw that it was outstripping her ability to manage the backups and recover the data. This situation drove her to examine not only how to better backup and recover her company's data but do so in a more cost-effective means while creating an offsite option for disaster recovery. This situation was amplified as Darwin Partners grew and added offices in San Francisco and China as these&nbsp;offices&nbsp;needed to remain operational should a disaster strike Darwin Partner's Wakefield, MA, data center. </p>
<p>She initially examined more traditional options of setting up a secondary data center or doing a collocation with another company but both of them came with a huge price tag. This prompted her to take a look at AmeriVault's online backup service in 1999. While maintaining full control over her backup requirements, she wouldn't have to worry about scaling issues and could quickly add servers or remote sites on demand. Data sets, retentions and frequency were all easily customizable while AmeriVault would seamlessly manage the back end storage. </p>
<p>Jeannine's decision to switch to online backup in 1999 definitely represented a "thinking outside of the box" mentality at that time since only now, in 2007, is online backup maturing among SMBs. But as Jeannine can attest, she now spends far less time thinking about whether or not last night's backups happened plus she now has a number of viable and affordable options to recover her company's data should a disaster strike.</p>
<p>As Darwin Partners discovered, companies can not afford not to examine AmeriVault's online backup service as a viable offering. In addition to the benefits of eliminating tape management and monitoring daily backups, AmeriVault gives them more options to recover their data and, with new service offerings like <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.amerivault.com%2Freplication_services%2Fvirtual_disaster_recovery.html" target="_blank"><u><font color="#0000ff">RestartIT-VDR</font></u></a> and <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.amerivault.com%2Fdata_archiving%2Famerivault_dv.html" target="_blank"><u><font color="#0000ff">AmeriVault-DV</font></u></a>, new possibilities for disaster recovery and data archiving that they normally could not deliver in-house.</p>]]>

        <![CDATA[<font size="2">
<p>The October 2007 issue of InfoStor magazine ran an article entitled "<a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.infostor.com%2Fdisplay_article%2F308958%2F23%2FARTCL%2Fnone%2Fnone%2F1%2FIT%27s-new-%27dirty-little-secret%27%2F" target="_blank">IT's New Dirty Little Secret</a>" which includes an estimate from the Enterprise Strategy Group where they believe that 60 - 80% of data on primary storage today is static or persistent data. Static or persistent data is not accessed at all for 90 days or more after its initial creation which then consumes valuable storage capacity and data center power. This is "IT's new dirty little secret," says analyst Heidi Biggar.</p>
<p>While I do agree that IT may hide this information from business managers (or minimally does not draw their attention to it), this cover-up is probably not as sinister as it sounds. The deeper problem is that IT has no practical, economical and easy-to-implement-and-manage solutions for this problem. Archiving, virtualization and HSM (Hierarchical Storage Management) software are just some of the possible ways to tackle and address this issue that has been around for years. But even the InfoStor article brings out that only a limited number of companies have implemented this software&nbsp;and most have&nbsp;taken no action at all on the problem.</p>
<p>So why aren't more companies taking action? The answer is two-fold. First, taking action is not simple. All of the aforementioned tools usually require corporate buy-in, lengthy purchasing cycles and time to implement the software. Meanwhile the cost of disk continues to drop so they know, to a certain degree, buying more disk is always an option. Second, who will manage the software and new hardware once they acquire it? Buying cheaper disk storage systems or storing more data to tape saves money now but instead of managing just one or two expensive storage devices, they now have more hardware to manage. This introduces other risks and complexity into an organization and partially defeats the purpose for better managing the data in the first place.</p>
<p>AmeriVault, known for remote online data backup services, also delivers online file archiving for&nbsp;lifecycle management of this static data. This is a natural fit for a common problem that many businesses face - backup windows. AmeriVault uses backup software that takes block-level changes and compresses data sets with traditional algorithms and deduplication. Combine that with their new archiving software that archives static, less critical data and all-night backup may now take less than a few hours so the backup window issue disappears. </p>
<p>Managed archiving solves the hardware burden as well by eliminating the corporate need to manage the storage devices on which the static data resides. Instead this task falls to the MSP who maintain the backend hardware. Administrators set policies that establish what data is archived and end users access the data as usual&nbsp;with the file name doubling as a stub pointer to the offsite archive. </p>
<p>IT is just like everyone else, who wants to talk about and publicize problems when they have no answer for them? The combination of online backup and archiving offered by AmeriVault as part of its <a  href="http://www.dciginc.com/redirect.php?site=http%3A%2F%2Fwww.amerivault.com%2Fdata_archiving%2Famerivault_dv.html" target="_blank">AmeriVault-DV </a>data archiving service gives SMBs a new option to consider which they may find more palatable than many of the other solutions currently on the market.</p></font>]]>

        <![CDATA[<font size="2">
<p>Scott Bush, AmeriVault's Director of Marketing, and I regularly discuss over the phone current trends that are shaping the future of online backup. It was during one of these conversations that Scott just happened to mention that AmeriVault relies heavily on Internet search engines for lead generation. </p>
<p>Now I usually view Internet search engines as means for consumers to find information to make decisions and buy products. But the fact that AmeriVault generates many of its new business leads through the Internet indicates that companies, not just individuals, are also using the Internet as a source for making buying decisions. Where it gets difficult is how do individuals in businesses substantiate the quality of the information they are reading to make critical buying decisions?</p>
<p>I find this topic particularly intriguing because with most consumer products, you can research them to the nth degree and what makes them different. Whether it is Zest soap, Chef Boyardee ravioli or Jiff peanut butter, you can find nutrition information, where it was made, who uses it, how long it lasts under ultraviolet light before it starts to glow and, with some digging, how it compares and contrasts to other like products. But try to find current information about products and services that businesses buy, that information suddenly becomes difficult to come by.</p>
<p>Current information on online backup providers is especially difficult to find. On the surface, it might be easy to think that online backup providers are exactly alike, especially if one is not familiar with the space. However it quickly becomes evident that online backup providers refer to themselves as Managed Service Providers, or MSPs, because they do more than just backup data. Email and file archiving, hosted replication, data classification and disaster recovery are services that they either offer now or are considering for the future.</p>
<p>The possibility of SMBs obtaining these types of services from an MSP like AmeriVault is not so far-fetched. SMBs rarely have the time, money or staff to develop these data management disciplines themselves. Since MSPs are already managing their backup data and have become backup experts, they have easy access to&nbsp;SMB data and can can look to offer services like archiving, classification and disaster recovery. Since MSPs can support multiple clients, SMBs are better off leveraging the seasoned MSP expertise rather than bringing technologies in house that they have to learn, maintain, and dedicate valuable resources to. After all, don't most SMBs out-source their payroll? So the leap to out-sourcing their data management is not a big one to make.</p></font>]]>

        <![CDATA[<p>VMWare has captured the attention of the storage space unlike any other technology in quite some time. VMWare's primary value proposition is virtualizing multiple physical Linux, NetWare, Windows and Solaris servers on a single physical server. While companies may first look at VMWare from a cost-saving perspective to minimize the number of production servers they need to manage, companies may hesitate in adopting it.</p>
<p>IT managers are, by their very nature, risk-averse so while they may see the value proposition of VMWare, they know that beneath the surface of every new technology, even one such as VMWare, lies unknown issues.&nbsp; IT managers do not want to be the first to uncover and have to work through those issues. So while the idea of virtualizing 5, 10 or even 20 physical servers onto one physical server may sound appealing from a financial and technical perspective, it also creates the harsh reality that a single server hosting multiple virtual servers creates a single point of failure. Historically, when an IT Manager lost a single physical server, only application services on that server were negatively impacted. Forward looking, if the hardware supporting a VMWare server fails, all of the application services on that VMWare server also fail. </p>
<p>The other concern with VMWare is that it requires different skill sets than most entry-level and mid-level system administrators typically possess. Managing a VMWare instance may require understanding and supporting technologies such as N-Port ID virtualization (NPIV), memory ballooning, iSCSI SAN support and storage I/O traffic prioritization. These are not trivial tasks and certainly not skills that the average Linux, Solaris or Windows administrator are likely to have acquired in their current roles. IT managers are then faced with helping their staff acquire new skills and transition from their existing environment to an emerging virtual datacenter.</p>
<p>This is where using online backup in conjunction with a company's real servers or the virtualized servers can take some of the risk out of this transition. An online backup service provider should be able to support the following restore capabilities:</p>
<p>•&nbsp;Physical-to-Virtual (P2V) - Backup data from a physical server is restored to a virtual server<br />•&nbsp;Virtual-to-Virtual (V2V) - Backup data from a guest system is restored to another guest or virtual machine<br />•&nbsp;Virtual-to-Physical (V2P) - Backup data from a guest is restored to a physical server</p>
<p>Of these three, companies considering virtual datacenters should evaluate the physical-to-virtual (P2V) option first. Since companies often have multiple physical servers in multiple locations, the idea that one should replace all of one's existing physical assets with one new virtual server is perceived as too risky for most. Using online backup with existing servers and then using virtualized servers to recover data gives companies a viable and safer means to start the transition to a virtualized environment since it gives them a justifiable means to understand how virtualization works.</p>
<p>To execute P2V recoveries, companies can use online backup services from AmeriVault to first backup their current servers. They then can experiment with VMWare in a disaster recovery scenario to simulate recoveries of data from any of their servers to virtual servers. What makes this combination practical is that companies can solve their immediate backup problems using online backup; they can provide a viable option to recover any of their servers in any site using VMWare; and they can use this as an opportunity to expose their existing administrators to VMWare in a relatively risk-free manner. This creates a win-win-win scenario for everyone involved and one which companies would be advised to explore.</p>
<p>Lastly, if virtualization is being considered, one must ask if the legacy backup method will adapt to the new virtualized environment.&nbsp; With online backup, you're going to use the Internet and not physical hardware, therefore eliminating any roadblocks and paving the way for future backup and recovery flexibility.</p>]]>

        <![CDATA[In this first blog entry for AmeriVault, DCIG Inc wishes to thank AmeriVault for agreeing to be a beta client for DCIG Inc's new blogging service. As part of this beta, DCIG Inc will provide AmeriVault with three blog entries a month written by a DCIG Inc analyst. In these blog entries, DCIG Inc will discuss and examine topics germane to AmeriVault's business model - online backup - and is directed to customers who already use it or are considering its adoption. So without further ado, welcome and read on!<br /><br />In case no one has noticed, it is October 2007 and companies are still struggling with backup. Whether it is troubleshooting a failed tape drive, trying to find a tape lost in a snow bank or wondering who stuck what label on which tape, it is ridiculous to think that high paid systems administrators are spending endless hours managing tapes.<br /><br />Problems like these are part of the reason that DCIG Inc views online backup as one of the critical technologies that small and midsize businesses (SMBs) need to evaluate. In just the last few years, online backup has grown from a nascent industry to a viable option for backup for SMBs. Online backup managed service providers (MSPs) offer cutting edge data protection technologies such as agent-less backup software, deduplication, redundant data centers and technical staff whose job is doing backup - features and expertise most SMBs only wish they had the time to understand and develop in-house.<br /><br />Recently I had a conversation with Scott Bush, AmeriVault's Director of Marketing, about this very topic. Bush agreed that a number of online backup MSPs offer these services but he brought out that backup MSPs are starting to mature and differentiate themselves. For instance, like other backup MSPs, AmeriVault licenses Asigra's TeleVaulting software for backing up data at its client sites. Where AmeriVault seeks to differentiate itself is by taking advantage of some of the inherent features found in Asigra's TeleVaulting to help keep its clients' backup costs under control.<br /><br />One such feature is Asigra TeleVaulting's backup lifecycle management (BLM) feature. Using BLM, AmeriVault can set policies that manage which tier of storage backup data is kept on. AmeriVault currently uses three tiers of storage and, by default, keeps all of a clients' data on its most highly available storage and then replicates the data to a second data center. However, for clients who backup older data and are willing to take advantage of this feature, AmeriVault can classify backed up data by age and move it to other tiers of storage using Asigra TeleVaulting's BLM feature.<br /><br />Bush cautions that users will assume a little more risk in this scenario since the data on the lower tier storage is not replicated to a second data center. However since the data is older and rarely or never accessed anyway, users can still keep their data online, lower their backup costs and have some assurance that only in a truly catastrophic situation which impacts AmeriVault's data center is their data somewhat at risk.<br /><br />As this example with AmeriVault illustrates, services provided by online backup MSPs for SMBs are evolving beyond just backup. Though online backup helps to takes the sleepless nights and daily struggles out of backup, online backup MSPs like AmeriVault are also taking SMBs to levels of backup management that most have never considered. In so doing, AmeriVault solves immediate SMB pain points while providing them a roadmap for their future backup needs. <br />]]>
