We are currently running VMware ESXi 5.0 on a Dell PowerEdge R815. For our storage device we are using an connection iSCSI to a Dell EqualLogic PS4100X. We are attempting to run 80 Windows vm's (20 per datastore, datastores on the SAN) that write a lot of data to the disk. As a result we are seeing performance issues on the EqualLogic due to the high number of iops. Can anyone recommend ways to prevent excessive iops or other perfomance bottlenecks? Is running the vm images from a local disk better than off the SAN?
