I'd like to know what could be the problem or indication if I got this warning every morning between 6 AM - 7 AM ?
Status: Warning (Yellow)
Alarm: Host disk write latency
Time: 6/11/2010 6:26:56 AM
Level of Disk write latency is above 65 Millisecond
ESXi 4.0 with local VMFS datastore of RAID-1
2x 1 TB WDC10EARS 64 MB buffer 7200 rpm SATA-II
it happens just in the morning when there is no significant workload in the server (it is still outside of business hours).
any kind of suggestion would be greatly appreciated.
