Many thanks Justin. This is the first time I am hearing about an Infiniband card operating in Ethernet mode. These cards come with two CX4/SFF 8470 ports. It's not possible to connect standard Ethernet cables that I know of (not even SFP modules). Do you mean that they can operate in Ethernet mode over the CX4 cable? GrzegorzJhelp
