I am running ESXi 5.1.0 - 1065491 with locallly attached storage.
I am getting spikes of high I/O and I get this error in the event logs:
performance has deteriorated. I/O latency
increased from average value of 2888
microseconds to 168219 microseconds.
We recently upgrade from ESX 4.0 to ESXi 5.1U1. Where should i be checking to find the culprit for the high IO?
Also I have to try multiple time to login through vsphere, i get the error cannot connect then magically I can authenticate and login.
