F.2 InfiniBand Cabling Tables for Rack-Mountable Servers

F.2.1 Cabling Topology and Rules

All of the cables in factory-integrated rack-mounted systems are labeled with their origin and
port destinations. You need to refer to the cabling tables only if you need to recable a dismantled
cluster using new, unlabeled cables.

F.2.1.1 Using the Cabling Tables

From the cabling tables listed in the appendices of this guide, select the appropriate cabling table
that matches the configuration of your cluster.
Verify the tables by comparing the port addresses in the tables to the port addresses printed on
the cable labels. These labels identify the origin and destination of each cable, such as from a
port in the interconnect, to a port in the HCA that is installed in the node.
Each cluster component, (interconnect chassis or cluster node) has a logical address defined by
its location in the cluster rack, and its position in the cluster topology. When two InfiniBand
interconnects are present in a configuration, switch 1 is on the bottom and switch 2 is immediately
above it. The HCA installed in a node's PCI bus has two ports, port 0 and port 1. For example,
the following table provides two sample origin and destination addresses:
