The promise of a storage hypervisor is to do for storage what server hypervisor technology did for servers, providing the same utilization, flexibility, and cost savings benefits.

Where we recommend that Virsto vDisks be used in a failover cluster is for the VM image and user data.  This is where some of Virsto's unique features have real value...

Much of that 74% savings comes from our very efficient thin provisioning implementation, so it won’t conflict with the benefits dedupe can provide.

Ultimately the administrators who manage storage are going to have to implement new processes that, while possibly already available today, are not being widely used. The question for you is: when does that happen for me?

Great taste or less filling? I can just imagine Hyper-V systems administrators, just as emotionally charged, having heated debates about which is better when it comes to virtual hard drives (VHDs) – high performance or thin provisioned.

Maximizing utilization of infrastructure you've already paid for is a good thing.  You'd do it for manufacturing, you've done it for servers, why not do it for storage too?

Even after a couple years at Virsto, I am still amused at advice to solve performance issues by wasting disk space.

If you’re about to embark on a virtual desktop infrastructure (VDI) project, what formula are you using to determine the storage configuration you need on the back end to meet your performance requirements?

Clearly, Hyper-V with Virsto can significantly outperform native VMware, assuming the same hardware configuration, in situations where you want high performance, thin provisioning, and snapshots at the same time.

If you’re looking to enhance your Hyper-V experience with storage performance, storage capacity consumption, provisioning times, snapshot backups with Windows Volume Shadowcopy Services (VSS) and Microsoft System Center Data Protection Manager (DPM) or cluster shared volumes (CSVs), then you will be interested to know more about Virsto. 

Dynamic Memory will highlight storage performance problems

Service packs are coming out Feb 22 for Windows Server 2008 R2, and one of the key new features is dynamic memory (see Jon Brodkin's article).  By boosting how efficiently Hyper-V makes use of memory, this should boost VM density on a given host for a given set of resources.  This claim tracks pretty closely with one we've been making for storage resources - that with a simple hypervisor plug in we'll let you support more VMs on a given storage configuration by significantly increasing the performance you get on a per spindle basis.

We are extremely proud of the development team at Virsto Software. It is amazing how powerful a platform we have delivered in such a short time, with such a tight little team. It has been a pleasure to be a part of it.

As good as the team is, we need more people. We have a number of interesting projects in our roadmap, and we need help!

Last week on the MSDN blog, an article was posted about the virtues of Microsoft Hyper-V differencing disks in VDI environments. Based on recent experience testing VDI IO performance, there are some serious issues that must be considered.

This post is in response to a comment from Eric Gray to my post about hypervisor IO performance.

Eric asked for more details about how to run certain IO benchmarks, so I'll provide that here.

Over on the TechNet site, VMware’s Eric Gray asked a couple followup questions to my guest post on the Microsoft Virtualization team blog. I can’t give a complete response in a brief comment, so I’m moving the discussion over here to the Virsto blog.

There is nothing like real customer exposure for understanding truth.

Since our Virsto One release we have been getting great positive feedback. Including some valuable questions on various aspects of the product. The one area that seems to bring the most questions is the architecture of our filter driver and our VHD model…

As part of Virsto's beta test program, we've had the pleasure of working with Windows IT professionals who know a lot about virtualization and Microsoft Windows Hyper-V. A couple of these customers have recommended blogs.
