We are using memory based storage with a product called Atlantis. It is very fast. Read latency is less than 2ms on average.
We are set to static high performance and using the latest firmware updates
This is a pilot test, so we are only testing ten VMs right now (<5 per host), so we are not close to exceeding CPU or memory utilization.
On the % Ready, it is not straightforward to determine. The CPU Ready summation in milliseconds for the hosts are 40000 to 50000 milliseconds on the daily chart. I believe this is sampled every five minutes, so this would be 16%. We deployed the maximum expected # of VMs, although only a couple are being used. We are expecting a maximum of 50 VMs per 4 processor host.
I am wondering if changing them from 2 vCPU to 1vCPU would actually improve performance ?
