traffic from the other I/O module goes to the second fabric interconnect. You cannot connect two I/O modules
to a single fabric interconnect.

Guidelines for Pinning
When you determine the optimal configuration for pin groups and pinning for an uplink port, consider the
estimated bandwidth usage for the servers. If you know that some servers in the system will use a lot of
bandwidth, ensure that you pin these servers to different uplink ports.
