There is a recurring situation that I face whenever I am deploying a new VMware View environment (also applicable to any vSphere deployment) . Due to natural limitations on number of IOPS per datastore (LUN), VMware recommends that you size your datastores for a maximum of 64 virtual desktops. This number could be higher, however you will need to pay attention to the number of IOPS required to support the workload, and verify that each LUN and backend array/spindles are able to provide the required performance. Normally this performance is measured by the latency number between I/O requests. There are references that mention that if I/O latency is higher than 10 milliseconds on average and higher than 20 milliseconds at peak your workload is under I/O contention.
