I have IBM 3850m2's with 3 82571Es in them, I am using ESX 3.5 with NFS as my storage protocol, so I'm hitting the network pretty hard. THe cards are connected to a storage swtich running in a trunked config (2 gig each trunk).
I'd like to know if these cards support IOAT and if they do what are the benefits of enabling it? Lower latency? Lower CPU utilization%?
