New V-locity 3 Virtual Platform Disk Optimizer Released at VMworld

by Colleen Toumayan 31. August 2011 02:20

Cures Pains from I/O Bottlenecks, Slow VMs, Slow Migration, Resource Conflicts, 

Wasted Storage Space and Slow Backup Speeds

Diskeeper Corporation announced at VMworld the release of new V-locity® 3 virtual platform disk optimizer for VMware®

V-locity 3 delivers invisible background optimization to give maximum I/O performance on virtual servers. 

V-locity 3 now has full integration with VMware ESXi as well as existing support for other platforms such as ESX, and Microsoft Hyper-V™. Other developments include V-Aware™ technology which detects external resource usage from other virtual machines on the virtual platform and eliminates resource contention that would otherwise exist on the same Host Server. New CogniSAN™ technology detects external resource usage within a shared storage system, such as a SAN, and allows for transparent optimization by never competing for resources utilized by other VMs over the same storage infrastructure. CogniSAN does this without intruding in any way into SAN-layer operations. Lastly is the new automatic zeroing of free space which is a powerful engine that zeros out unused data blocks on virtual disks and makes virtual disk compaction easy.

The Summer Blockbuster Sequel: V-locity 3.0

by Michael 24. June 2011 07:00

Coming Soon: V-locity 3.0 (virtual platform optimizer)  has some fantastic new features in it we're sure you’ll like, including:

+Full Support for ESXi Server (in addition to existing support for ESX and Hyper-V)

+Reduced installation effort for ESX Servers (no installation on Host)

+New CogniSAN technology (for storage area networks)

+New V-Aware technology (for any virtualization platform)

+Automatic zeroing of free space (for thin/dynamic virtual disks)

+Added support for virtualization platforms such as XenServer, RHEV, Oracle VM and more

We are just a few short weeks from releasing it, and could use your help. If your interested in catching a “sneak peak” (our final release candidate build), and are interested and able to install, evaluate and then comment (fill out a 10 minute online survey) on this software, simply fill-out a Non-Disclosure Agreement (NDA) located here.

Fax the signed NDA to:
Fax: 818-252-5514

Please add the following to the Fax cover page:
Attn: Field Test Administrator/V-locity Field Test

Alternatively you can email the signed NDA (scan in the pages with your signature) to our Field Test administrator. Please add "V-locity Field Test" in the subject line.

Storage VMotion and GOS fragmentation

by Michael 3. December 2010 06:57

I had a test run here internally in order to make a point about what does, or more specifically "does not", happen when you VMotion/SVMotion a Windows Guest OS (GOS). We wanted to demonstrate that, while VMware is copying the VM to another host/storage, it does nothing about the internal fragmentation of files in Windows.

We felt this was a valuable demonstration as one of the old (1980s) ways to "fix" fragmentation was to copy off the files/backup, reformat the volume, and then copy back/restore. This offered a degree of success, but required taking the data offline in order to get rid of most of the fragmentation. On a side note, backing up/copying fragmented files takes a lot longer than it would on contiguous and ordered files.

Anyway, S/VMotion is such a cool feature because it works on live VMs. So, if the VMDK movement somehow did align/reorder files in Windows, it could be a great solution to Windows file system fragmentation! So here's how we tested...

1. Setup 2 ESX 4.1 Servers with iSCSI storage and vCenter with SVMotion capability.

2. Create a VM with Windows 7 in one of the ESX Server storage (Ex: Storage1) and a 20 GB Thin virtual disk.

3. Using an internal tool, create moderate fragmentation on the virtual disk (80k fragments, average fragments per file around 3.0, around 50% free space).

4. Install V-locity with all features (e.g. defrag, IntelliWrite, etc...) disabled. This is just so we can run a fragmentation analysis and save the reports.

5. Save the "Before SVMotion" analysis report, and then stop V-locity Windows Service (to make sure it is entirely inactive).

6. Using SVMotion move the live VM to the other ESX Server storage (Ex: Storage2).

7. Once the move is completed, restart the V-locity Windows Service and perform a post "After SVMotion" analysis.

8. Save this job report.

We saw what we expected, given VMotion leverages Changed Block Tracking (CBT) technology and is block, not file based. I attached the report, so you can see the side-by-side analysis data, files in Windows are not defragmented in an SVMotion. Now, that's not to say possible fragmentation of the VMDK files themsleves (on VMFS datastores) was not affected, but that's a topic for another post. 

Diskeeper Corporation to Exhibit V-locity 2.0 Virtual Platform Disk Optimizer at Interop New York 2010

by Colleen Toumayan 20. October 2010 04:50

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 Interop New York 2010.  

Location: Interop New York 2010

Date:  October 20th and 21st, 2010

Booth: 725

Venue: Javits Convention Center, New York, New York 

Key to seminars and discussions at Interop New York will be Virtualization. Virtualization is being rapidly adopted because it can lower the cost and increase the flexibility of IT infrastructure.  A new white paper, The Importance of Defragmentation in Virtual Environments, co-authored by Osterman Research and Diskeeper Corporation, demonstrates that virtual environments require defragmenting even more than physical environments. This is due to the fact that virtual environments support multiple operating systems and create a higher intensity of disk activity.
