No. Believe it or not I spent a long time looking everywhere but the Casper wiki. Should have thought of that because that's where we got the Myricom card from.
Those listed are at the higher end of the price range I've seen. Looks like ~$10k is the amount I should be prepared to spend. Am I right to interpret the XFP ports as something I could convert CX4 to use with a transceiver?
