InfiniBand Connections

The following InfiniBand connections are set up for the Database Domain in both SPARC T4-4 servers in this example scenario.

At the SPARC T4-4 Server Level

Two of the four dual-ported Sun QDR InfiniBand PCIe Low Profile HCAs in the SPARC T4-4 server are assigned to the Database Domain, installed in these slots in the SPARC T4-4 server:

• Express module slot 1

• Express module slot 9

Both ports in each InfiniBand HCA are bonded together, resulting in two IPoIB interfaces for the Database Domain (one IPoIB interface for each InfiniBand HCA). The two ports in each InfiniBand HCA connect to a different leaf switch to provide redundancy between the SPARC T4-4 servers and the leaf switches. See InfiniBand Private Network Physical Connections (Exadata Storage Servers) for more information.

At the SPARC SuperCluster T4-4 Level

The Database Domains in both SPARC T4-4 servers have InfiniBand connections to the InfiniBand leaf switches, Exadata Storage Servers, and the shared storage on the Sun ZFS Storage 7320 appliance.
