InfiniBand Connections
The following InfiniBand connections are set up for the Application Domain running Oracle Solaris 10 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 Application Domain running Oracle Solaris 10, installed in these slots in the SPARC T4-4 server:
-
Express module slot 7
-
Express module slot 12
However, the InfiniBand network setup for the Application Domain running Oracle Solaris 10 is set up differently from the Database Domain:
-
One port from each InfiniBand HCA are bonded together, resulting in one IPoIB interface for the Application Domain running Oracle Solaris 10
-
One port from each InfiniBand HCA are used for the optional Oracle Solaris Cluster interconnects
In this example, the following port are used for InfiniBand connections for the Application Domain running Oracle Solaris 10:
-
InfiniBand HCA installed in express module slot 7 – Port 1
-
InfiniBand HCA installed in express module slot 12 – Port 2
At the SPARC SuperCluster T4-4 Level
The Application Domains running Oracle Solaris 10 in both SPARC T4-4 servers have InfiniBand connections to the InfiniBand leaf switches and the shared storage on the Sun ZFS Storage 7320 appliance. However, the Application Domain running Oracle Solaris 10 will differ from the Database Domain in that it would not access the Exadata Storage Servers, which are used only for the Database Domain.
