New V-locity update (build 2.0.25)

by Michael 1. September 2010 04:14

We have a new update available for V-locity 2.0 users. Here is a list of fixes and features we added:

Fixed several 508 compliance issues in the UI.

Fixed a communication error message in the UI.

Fixed a problem with VMware host service start.

Fixed a synchronization problem in environments with a very large number of physical disks.

Fixed a Guest/Host synchronization problem with ESX Server 4.1 (GOS with V-locity Guest did not appear in Host UI).

Fixed several crashes in the debug build of the Windows service.

Added Group Policy support.

 

Added SCOM support. A SCOM Management Pack for V-locity is included with a license of Diskeeper Administrator.

Just Released: V-locity 2.0!

by Colleen Toumayan 20. July 2010 06:12
BURBANK, CA -- 07/20/10 -- Diskeeper Corporation has officially shipped V-locity™ 2.0, 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.

Already a VMware and Microsoft partner for its Diskeeper® performance software, 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.

As virtualization platforms begin to age, fragmentation of files in Windows host and guest operating systems generates more disk I/O than should be necessary. Fragmentation creates more overhead on the OS and file system. While CPU, Network, and memory resources may allow for greater VM density, the disk subsystem can become a virtualization "high" hurdle.

"Fragmentation clogged disk subsystems can lead to an inability to run more VMs on given hardware infrastructure, and lead to disk performance bottlenecks for VMs that share a common storage subsystem," notes Diskeeper Product Manager, Michael Materie. "V-locity is designed to alleviate the 'virtual' disk bottleneck for VMs and provide a faster and more efficient computing platform for new consolidation and provisioning initiatives, without having to add more hardware."

"First of all, when building out my environment I make sure to have fast hard drives, controllers, etc., in order to make sure not to suffer bottlenecks. In addition, I am very careful about not over-committing resources. However, I was shocked to see, after deploying V-locity, how much performance increased on the servers I had hosting disk-intensive operations. This includes our database server, our Exchange server, and to a certain extent, two terminal servers," stated Bill Philpot Manager of Information Technology at Mesa Industries, Inc.

Diskeeper Corporation's proprietary technology, IntelliWrite writes files in a non-fragmented condition. Copy on write solutions (e.g. as used by Snapshots) take action on changes to data at a block level. Moving data, as is done in a defragmentation job to consolidate file fragments in a logical file system, can trigger copy on write solutions to take extra actions such as using more storage capacity, unnecessarily. Writing a file contiguously eliminates the need to defragment it after it has been created.

InvisiTasking® technology, another Diskeeper Corporation proprietary technology, is specifically engineered to allow "background" applications to operate with zero impact/overhead on a system. With V-locity 2, the InvisiTasking technology has been "enlightened" to operate across a virtual platform. Even as more VMs are added to a host platform or dynamically migrated to new hosts (e.g. vMotion, Live Migration), the enlightened InvisiTasking will continue to dynamically adjust to changing environments, providing V-locity 2.0 users with "Set It and Forget It" ® optimization of their virtual disk platforms.

V-locity also frees up vital storage resources by eliminating virtual disk "bloat." This is the wasted disk space that takes place when virtual disks are set to dynamically grow but don't then shrink when users or applications remove data. V-locity actually compacts the virtual disk, thereby preventing waste and allowing IT Managers to better allocate their virtual storage resources.

V-locity has four unique solution sets:

  • InvisiTasking - coordinates resource usage to ensure defrag is 100% invisible

  • IntelliWrite - prevent fragmentation and offer 100% compatibility in all environments

  • Virtual Disk Intelligence - automatically detects and configures based on virtual disk type

  • Virtual Disk Compaction - shrinks/compacts virtual disks that are set to grow-as-needed

V-locity consists of three components:

  • V-locity Host installed in the VMware ESX Host or Windows Server 2008/R2 operating system running Hyper-V.

  • V-locity Guest installed in all Windows virtual machines.

  • For VMware ESX platforms: V-locity includes a small application that allows you to remotely connect from your Windows desktop to the V-locity Host component on an ESX system.

Note: On Windows platforms, each component will optimize its respective OS; performing defragmentation of files and consolidation of free space. This minimizes unnecessary I/O passed from the OS to the disk subsystem and aligns data on the drives for optimal access.

New V-locity White Paper

by Michael 24. September 2009 08:26

Optimizing the disks of virtual platforms is an absolute must for performance. Typically even more so than on physical platforms.

Topix Technologies, an IT Analyst group out of Paris, France recent completed a study about the effects of fragmentation on the modern virtual infrastructure. They used V-locity to restore performance to the high service levels IT departments and providers are required to deliver. Check out the performance results in the chart below or read the full report here.

V-locity success story from our neighbor up north (Oregon)

by Colleen Toumayan 19. August 2009 09:11

I am enjoying V-locity. It has made a difference in performance, especially with some of my virtual machines.

One major feature I like is the built-in functionality to compact the VHD files. My hard drive was running low on space, but I knew my virtual machines weren’t using that much and V-locity told me which virtual hard drives to compact. I did that and it freed up a lot of space.  

We are running NextGen HER (Electronic Medical Records ) which generates hundreds of files daily, but we don’t have to worry because every night V-locity puts them in their place! The speed of our virtual guests and hosts and increased dramatically as well as our biggest file server that serves 170 users.  I also like how unobtrusive V-locity is… I don’t even notice that it is there really. I am excited to see Diskeeper [Corporation] on the cutting edge!
