IOPS

Esxi 6.5 > AFF220 (24xSSD) > NFS using a single 10Gbe SFP+ connection.

 

IOmeter giving 40.000 IOPS when doing 4k 100% read random (Inside VM). Tried adding more workers, but the 40k. appears to be the limit.

 

Is this a good number or would it be a benefit to modify ESXi settings like queue depth?

 

Also I am not sure if it is just the 10Gbe link maxing out?

 

Things run just fine, but its always nice to see some numbers for reality check.

Re: IOPS

Queue Depht should not be a item with NFS.

 

The VM can become the bottleneck. Try adding more VM's with, for example, 8 workers.
