I have two Dell r720 VMware hosts, and a Thecus n12000 Pro NAS. I just put an x540-t2 in each. They are connected through a Netgear ProSafe XS708e switch. There are no other devices on the network.
In all three machines, the port nearest the PCI is running 10Gb, and the other port is at 1Gb. The lights on the cards, and on the switch, all agree with this. One yellow, one green, for each endpoint.
How do I get both ports on these cards to run 10Gb?
