Diskeeper Corporation to Showcase V-locity 2.0 Virtual Platform Disk Optimizer at VMworld 2010

Diskeeper Corporation, innovators in performance and reliability technologies®, today announced that it is going to be presenting its V-locity™ 2.0 virtual platform disk optimizer solution at VMworld 2010.

Location:  VMworld 2010
Date:  Aug. 30 - Sept. 2, 2010
Booth: 1713
Venue:  Moscone Center, San Francisco, Calif.

Virtualization is being rapidly adopted because it can lower the cost and increase the flexibility of IT infrastructure. However, fragmentation, a phenomenon that dramatically reduces system performance, continues to be a problem as it is compounded in virtual environments. Not only can virtual storage become fragmented, but the underlying physical storage can become fragmented as well. Virtual disks, many of which can be housed on a physical disk, can become fragmented over time just like the physical disk(s) on which they reside. The result is a fragmented virtual disk on a fragmented physical disk, or fragmentation within fragmentation.

V-locity 2.0 is a new virtual platform disk optimizer designed to deliver invisible background optimization of all Windows® Guest operating systems running on the VMware ESX and Microsoft Hyper-V™ platforms. New to V-locity 2.0 is the addition of the breakthrough IntelliWrite™ fragmentation prevention technology originally introduced with Diskeeper® 2010. Utilizing IntelliWrite technology, V-locity writes files to the disk to prevent up to 85 percent of fragmentation from occurring before it even happens.

V-locity was made to create a virtual-specific product that not only performs defragmentation functions, but also synchronizes the complex and ongoing activity between host and multiple guest operating systems in a virtualized environment, even when configured on high-powered host systems with data stored in SAN environments.

"We deployed V-locity very shortly after deploying our virtual infrastructure, so there wasn't much time for any bottlenecks to develop.  We run V-locity on every Hyper-V virtual machine since it's free with our license for the Hyper-V hosts.  We did that mostly just to avoid the double defragmentation that can happen with virtual hard disks.  We've also got it on a physical Exchange hub transport server (and another one that is virtual) mostly to keep the log files intact.  The e-mail data is only on the hub transport servers temporarily during transit, but the log files change constantly.  It's also on the Exchange mailbox server to defragment about eight stores, almost all being over 100GB, and our main file share cluster.  Both of those servers store their data on an HP SAN," stated Eric Johnson from a Construction Industry site.

"The need for defragmentation is especially acute in virtual environments," said Michael Materie, Product Management Director, Diskeeper Corporation. "Because physical hardware in a virtualized storage environment must support more operating systems and can undergo even more disk access and more stress than in a non-virtualized environment, fragmentation of these unique environments requires a specialized approach. With V-locity 2.0, users can realize the benefits of full virtual efficiency."
