NFS datastore with one Window VM in it, in vSphere environment. AFF SSD aggr.
The user is complaining taking much longer to complete a job, and the graph shows about 75 ms latency in about 18 hours.
During the same period of the time for this volume, I can see in OCUM about 10 ms latency, and also 17k IOPs and 1000MBs throughput which is much and much higher than some other time.
I have checked around, I don't see any issues on the storage cluster. 10ms is not good, but not terribly bad neither. So, how do I tell if the slowness was really caused by the Window VM or the storage cluster?
