Came across this thorough analysis of Windows 7 IO behavior put together by Jim Moyle.
The document named “Windows 7 IOPS for VDI: Deep Dive” cover many Windows 7 IO aspects with specifics for VDI sizing and deployments. The paper yet explains how to measure IO at the guest OS, hypervizor and application layers, including antivirus.
At the end you will find that the document is biased and tries to push a given product. However the quality of the paper is not overshadowed by that.
It’s a Good Read…
