Cabling and Switches

The cable installation uses a standard InfiniBand (IB) 4X cable. Any InfiniBand cable that has been qualified by the vendor should work. For SDR, the longest passive copper IB cable that QLogic has currently qualified is 20 meters. For DDR-capable adapters and switches, the DDR-capable passive copper cables cannot be longer than 10 meters. Active cables can eliminate some of the cable length restrictions.

InfiniBand switches are available through QLogic.

NOTE:

If you are using the QLE7240 or QLE7280 and want to use DDR mode, then DDR-capable switches must be used.

The copper cables listed in Table 4-2are available from QLogic:
