I would be interested in knowing more about this i do have one of these boards in one of my ESXi Hosts, but havent gotten the time to hook the switch into it as of yet... did you try swapping cables/firmware etc?Anyone else having connection issues? Since my gigabyte pesh-2 is connected on 10gbit (2x x540) connection keeps dropping. Need to restart the server to get it up again, so think a board issue?
