Exadata Database Machine
For high availability purposes, connect the active port of the InfiniBand card included in
each of the Oracle Business Intelligence Machines to the leaf 1 switch (Sun
Datacenter InfiniBand Switch 36 installed in the lower unit of the Oracle Exadata
Database Machine). In addition, you should connect the passive port of the InfiniBand
card included in each of the Oracle Business Intelligence Machines to the leaf 2 switch
(Sun Datacenter InfiniBand Switch 36 installed in the upper unit of the Oracle Exadata
Database Machine). Port 1 can function as the active port, and port 2 can function as
the passive port.

On the leaft switches of the Oracle Exadata Database Machine, the following
free ports can be used:
Ports 5B, 6A,6B,7A,7B, and 12A
