Hello,
This may be more of a VMWare question. From within Data Fabric Manager, I am seeing a spike in latency on a NetApp volume used as an NFS datastore. DFM shows a spike in NFS latency of 50 ms on the volume.
However, a virtual machine's performance counters in vSphere show a spike in Virtual Disk latency upwards of 700ms for the same "latency event".
Any idea what might account for this difference in latency reporting between the NetApp (DFM) and ESXi? I expected there to be some difference for obvious reasons but I didnt expect to see a difference of this magnitude.
Thanks, Phil
