- What is the difference between an active and a passive cable?
- What is the difference between QSFP and QSFP+?
- Given the choice between copper and fiber, for a very short distance like 3 feet max, is one better than the other or approximately equal?
- The Mellanox card MHQH19B-XTR Mellanox ConnectX-2 VPI QSFP QDR InfiniBand 10GB Ethernet PCI-E HCA says it is ethernet and infiniband. I thought those are different technologies altogether?
- Does this card support verbs programming and is the driver supported by relatively modern OS like CentOS 6.x?
Finally, even if no one knows that question, what is the right cable for this card?
