Actualy I am using two Dell PowerEdge R805 Servers with an Dell MD3000i iSCSI Storage.
Since the MD3000i is no more on the compatibility list for vSphere 5.5 and I am getting a lot of I/O latency problems. I am searching for a new storage device.
At the moment the MD3000i is running with 15 NL-SAS 420GB hard disks (1 Hot-Spare).
So I was looking at Dell again at the newer MD3200i again. But I think I might be geeting I/O problems again while using iSCSI.
I would be glad if someone could give me any recommendations.
At the moment there are running 16 VM's, vCenter, two DC's, one Exchange, one fileserver.
