When I try moving a VM to another datastore sometimes VMware/SAN/Switches crashes. IOPS on the SAN (Equallogic 4000e cluster) drops to zero. All Vm's don't respond during this time. When the move crashes IOPS goes back up to normal level.
It is possible to move small machines but larger VM's always fails.
I'm using VMware 5.0, Dell powerconnect 5424 switches and a Equallogic 4000 cluster.
I reinstalled ESXi machines, updated the switches etc. Nothing helps.
Someone can help me?
