A look at the PyPy 2.0 release
IB was designed for a system interconnect within a rack (or a couple of nearby racks)
ATA and SATA aren't general interconnects, they are drive interfaces
10 GbE is a fair comparison for IB, but it was designed to allow longer cable runs, with fewer wires in the cable (being fairly compatible with existing cat5 type cabling)
Virtualization and InfiniBand

define a driver that does page allocation tricks to move data between the client and the host for zero-copy communication. at that point you beat anything that's designed for a real network.
then you can pick what driver to run on top of this interface, SCSI, IP, custom depending on what you are trying to talk to on the other side.

The big 10GIGE vendors are desperately pushing the insane FCoE stuff to try and get everyone to re-buy all their FC switches and HBAs since 10GIGe has otherwise been a flop. IB is 4x as fast, and 1/4th the cost of 10GIGE stuff from CISCO :|
