Hi! I would need an advice from those that use IB (as admins :) ) i have a choice between :
- Mellanox InfiniHost® III Lx HCA card, single-port CX4, DDR, PCIe
x8, mem-free, tall bracket, RoHS R5
- QLogic Single Port 20 Gb InfiniBand to x16 PCI Express Adapter
(Single Pack)
First, both of the above HCAs are old, I'd recommend going with either a Mellanox Connectx(-2) or Qlogics current 73xx.
Secondly, it's hard to recommend anything if you don't tell us what you're going to use them for. Does "parallel cluster" mean MPI?
Some random notes: * the InfinihostIII-lx is a cheap well working (although old) HCA * I'm guessing the Qlogic you had in mind was the QLE7280? if so: - 16x PCI-e does not fit everywhere

aside the price is there anything else that could help me make a discrimination between this two? (these will be used in twin servers for a small (up to 24 nodes) parallel cluster) Thanks! Adrian
