Infiniband cables - are they the same as SAS / SATA Multilane?

Recommended Posts

I'm looking into buying some used Infiniband equipment to experiment a little. So far I'm looking at:

  • Flextronics F-X430046 24-Port 4x DDR Infiniband Switch
  • Voltaire 400Ex Dual Port 4x 10GB PCIe HCA
  • QLE6140-SP Qlogic InfiniBand Host Channel Adapter (HCA) Single Port PCI-E Card

As far as I could research without actually trying it out, these should all work together even though the HCA's are 4x SDR and the switch is 4x DDR, but what I'm currenlty more confused about are cables - a search for 'Infiniband cable' returns a lot of results for SAS/SATA II Multilane Infiniband Cable - but are these really the same as 'real' Infiniband cables?

Sorry, really late to this conversation - if you're still looking, it really depends upon the connectors that you have on the switch and on the HCA. I've used a variety of CX4 and SFF8088 cables, really depends on the exact cards and switches you're getting.


what you are looking for is CX4 cables.

They should be the same for SAS expanders, but if you acquire CX4 infiniband certified cables, you will be good to go.
