Hi Abul,

InfiniBand has really come down in price, and you can actually get a 24-port
DDR (20Gb/s) switch for less than 8-port QLogic 8Gb/s switch. In addition,
the cards themselves will be less expensive as well. If it's at all
possible, I'd recommend going with InfiniBand. If you have any questions,
please let me know.
