I am seeing some strage behavior that I can't quite pin down.
2008 R2 VM (current tools), ESX 4.1 (491557), FC Storage (Compellent, or NetApp)
My Windows Server is running Exchagne 2010, has multiple disk presented to it split across multiple LSI SAS controllers. Under high workload I see response time repored in Windows to be upwards of 1 second. But in the VSphere Client and on the Storge system I see a resposne time of 50ms.
The storage and VSphere are reporting about the same response time but Windows is way out of wack.
Any ideas on this?
