Managing the IOPS Challenge in Large-scale Desktop Virtualization Deployments using Microsoft Hyper-V and Quest HyperCache

IOPS is the most challenging resource in hosted desktop environments. The goal of this study was to

assess how Quest HyperCache, at scale, can help with IOPS consumption. HyperCache is a feature of

Quest Workspace Desktop Virtualization (formerly vWorkspace) that is designed to drive down the IOPS

requirement while delivering faster performance for both VDI and RD Session Host. HyperCache will

drive down both disk read and disk write operations, with more emphasis on reads. Many studies are

available that look at the IOPS consumption of individual machines or over a single hypervisor. This

paper, however, looks at the impact on 3,000 virtual machines.
