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.
The copper cables listed in Table 4-2 are available from QLogic:
For cabling instructions, see “Cabling the Adapter to the InfiniBand Switch” on
page 4-17.
NOTE:
If you are using the QLE7240 or QLE7280 and want to use DDR mode, then
DDR-capable switches must be used.
