13.3 Work with the Default Rack-Level InfiniBand Partition

This section contains the following topics:

• Partition in Exalogic Machine

• Verify the Default Partition

13.3.1 Partition in Exalogic Machine

By default, the Exalogic machine includes a single partition at the rack level. All Exalogic compute nodes and the storage appliance are full members of this default partition.

Note:

Oracle recommends that you create IP subnets over the default IP over InfiniBand (IPoIB) link to implement isolate application deployments in the Exalogic environments. Each IP subnet will have a single multicast domain. When you create IP subnets, ensure that each of the interfaces per Exalogic compute node for these additional IP subnets above the default IPoIB subnet is bonded, for high availability (HA) purposes.

For more information, see the "Application Isolation by Subnetting over IPoIB" topic in the Oracle Exalogic Enterprise Deployment Guide.

13.3.2 Verify the Default Partition

You can verify the default partition and the partition key by running the smpartition list command on the command-line interface (CLI) for one of the gateway switches.
