Diskeeper Corporation at Interop New York 2011

by Damian 10. October 2011 02:59

We’ve just returned from the Interop Expo in New York, and what a show! The recent release of V-locity® 3 was extremely well received and interest in its innovations was very high. The Diskeeper Corporation booth was constantly attended by groups of CIOs and storage administrators eager to hear about the benefits of the new virtual platform optimizer.

The lion’s share of energy and buzz at the show surrounded virtualization and cloud computing. Leading vendors across these markets as well as storage, networking, and information security exhibited for large groups of virtual admins and IT executives. Shows like Interop are critical for decision makers to stay apprised of the ever-evolving IT infrastructure landscape, and excellent opportunities to get educated about what is truly needed to grow and maintain a virtual environment that runs on all engines for them.

In addition to being asked by numerous IT analysts about the innovations underlying the incredible advantages of V-locity 3, I was interviewed by TMC (Technology Marketing Corporation) about it.

The need to meet higher Service Level Agreements and reduce Total Cost of Ownership for shared storage have reached a new plateau in virtualized networks and private clouds—what V-locity 3 does best.

If you’re reading this and you were at the event, we’d love to hear about your experiences at Interop this year.

Diskeeper Corporation will be exhibiting at the Gartner Symposium in Orlando, FL next week. If you’re planning on attending this IT Expo, stop by the booth to hear firsthand about how V-locity 3 is improving virtual systems in a whole new way.

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.

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.
