I have an ESX 3.5 box with a Terastation (TS-RIGL/R5, FW 1.01 2TB iSCSI configured as RAID5). The connection is iSCSI. I have found that any VMs that I store on the Terastation drive are VERY slow to start up, shut down, or suspend. There is some difference in the performance of the VM but it is not as noticable as the control performance. The iSCSI is directly connected to the host on a 1GB NIC, so there is no interfering net traffic.
Can anyone tell me why the performance is slow and if I can fix it?
TIA
