I'm running ESXi 4.1. I have, what I believe to be, a disk I/O issue.. I have an EMC AX4-5i with two hosts.. Trying to do a storage vmotion (with the VM powered off) took over an hour before it would actually show the progress of 1%.. I had to cancel it..
Powering on a VM took over 3 minutes to login (and it was a fresh VM from template)..
Trying to install Veeam on a VM took over 60 minutes to get past the "analyzing" part..
Today I was copying files from VM to VM and while running esxtop the DAVG/cmd was over 3,000 on one of the hosts.. One of the VMs lived on host A and the other lived on host B.. Host B's esxtop DAVG/cmd didn't go over 100..
One thing to note is that the AX4's write cache is currently disabled because of a bad SPS.. I just don't know if that can cause such severe performance degradation..
Any help would be appreciated.
Thanks
