3.1.3 Connecting the Ethernet network
The DB2 pureScale system needs an Ethernet network to communicate between
servers. To connect servers with the Ethernet network, find an empty Ethernet
port on the back of the server, and connect it to an empty port on the Ethernet
switch with a regular RJ-45 cable.
3.1.4 Connecting an interconnect network
The DB2 pureScale system requires one high speed communication network,
which must be an InfiniBand network or a 10 GbE network. This section explains
how to set up the high speed communication network hardware.

70 Delivering Continuity and Extreme Capacity with the IBM DB2 pureScale Feature
Find an empty port on the InfiniBand switch and connect it to an InfiniBand port
on the server with a QSPF cable. Figure 3-8 shows the InfiniBand HCA adapter
that was used in our example.

10 GbE network
Find an empty port on the 10 GbE switch and connect it to a 10 Gb adapter on
the server with an SPF+ cable.
Important: If you use dual-port QDR InfiniBand HCA, ensure that you use
port 1 to connect to the InfiniBand switch.
Important: If you use dual-port adapter, make sure that you use port 1 to
connect to the switch.
