comment Exchange 2013 database corruption with event 476 in ESE
This is really strange. I do have some other Exchange environments with other storage backends (mainly ZFS with FreeNAS) and even with jumbo frames everything runs smoothly. The other thing to consider is that the jumbo frames setup are deployed and recommended by DELL once again, so we're using their own recommendation...

Yes. 9000 MTU on the point to point iSCSI links.

comment Exchange 2013 database corruption with event 476 in ESE
I'm really dissatisfied with those storage appliances from DELL. I've already deployed the latest firmware which fixes "random data corruption when a CPU fault happens on the controller", but this haven't solved the issue.

comment NAS recommendation for Xenserver
The problem here is the disks that you have. Using two disks in mirror will not give additional performance. For a VM workload you'll need a huge stripe of mirrors, ZFS is great with caching, but if your data is not "cacheable" it will give you the disk performance. Another thing to keep in mind is that XenServer needs time to coalesce the snapshots that you create. So the storage subsystem must be fast enough to handle all the activity. What you need now is to fill the requirements, like: what's the IOPS needed? Do you really need those snapshots? Can it work another way?

comment NAS recommendation for Xenserver
Spock, are you willing to buy a machine just to run FreeNAS? I've a production XenServer pool with more than 50 VM's running on a single iSCSI FreeNAS storage.
