Just What Is A Storage Hypervisor?

Tags: excessive storage spending, Hyper-V, virtualization, VMware

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.

Go after the low hanging fruit first

Tags: excessive storage spending, Hyper-V, Virsto VDI, Virsto VSI, virtualization, VMware, Xen

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?

Hyper-V enlightenment from a beer commercial?

Tags: excessive storage spending, Hyper-V, performance, Virsto One, Virsto VDI, Virsto VSI

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.

The Business Argument for Higher Storage Utilization

Tags: excessive storage spending, Hyper-V, performance, Virsto VDI, Virsto VSI, virtualization, VMware, Xen

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?

Dynamic Memory will highlight storage performance problems

Tags: Hyper-V, performance, virtualization, VM I/O blender

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.
