External InfiniBand Ports
The Server Switch Module has both 4x IB and 12x IB external connectors. The 12x IB connectors
support three 4x connections using an "octopus cable." This cable begins as one 12x connector (which
connects to your Server Switch Module), then branches into three 4x connectors that you can attach to
4x IB interfaces. The external ports are numbered 17 - 24. Ports 19 / 20 /21 and ports 22 / 23 / 24 are on
12x connectors and can be set up as 12x or three 4x connections.
