Im looking to add another SAN to my 3 host esx cluster. Im currently running a EMC AX-150i which just cant handle the io load i am presenting to it with SATA disks and it has no upgrade path. I am now looking at adding an EMC AX-4i with 12X146GB 15K SAS drives to our cluster and wanted to see what other members in the Philly area are already running this unit. Are there any hiccups I should be aware of with this unit. How is performance? Also i am interested in doing scheduled snapshots with Snapview and Navicli throughout the business day to reduce my RPO and wanted to see if anyone was using any of the advanced software features of the array. I have read online that Snapview creates crash consistent snapshots so I was concerned how stable the snapshots were when mounted and presented to another standby esx server or for rollback. Any info in regards to this would be greatly appreciated.

Thanks,

Rich
