Hoping you can clear something up for me. What is the easiest way to distinguish between poor disk performance of a disk array, and data contention produced by too many VM's per host per datastore
Would i be right in saying a comparision between datastore latency and the latency of the vms on that datastore would shed such light? Ie if the datastore latency is low by the vm latency is high it would indicate a point of contention?
