In vCenter, the datastore latency is very high. In esxtop. DAVG is good, but KAVG & QAVG is very high, but at the HBA level, the QAVG is low, what is the problem? The Storage is EMC VPLEX, at the storage side, the IOPS of the datastore is less than one hundred, and the latency is less than 1 ms.
Anybody knows? Appreciate.
