This white paper describes an end-to-end storage solution for enterprise scale Windows Server 2008 R2 Hyper-V deployments. This optimized storage solution demonstrates scalable performance and high availability that is required when deploying a very large number of VMs in a Microsoft virtualized environment. Large enterprise Hyper-V deployments with a large number of Virtual Machines (VMs) can be demanding on the storage infrastructure. In these environments, there is a lot of concurrent Input/Output (I/O) that contends for network and disk resources. This is especially true, for example, in Virtual Desktop Infrastructure (VDI) deployments, when many machines might boot concurrently at the beginning of the work day.
