Campus clusters:
Are connected using a high speed cable that guarantees network access between the nodes
Provide local high availability and disaster recovery functionality in a single cluster
Employ shared disk groups mirrored across sites with Veritas Volume Manager (VxVM)
Are supported for Storage Foundation and High Availability (SFHA) Solutions products including Storage Foundation Cluster File System High Availability (SFCFSHA) and Storage Foundation (SF) for Oracle RAC
The following high-level tasks illustrate the setup steps for a campus cluster in a parallel cluster database environment. The example values are given for SF for Oracle RAC and should be adapted for an SFCFSHA cluster using another database application.
The following high-level tasks illustrate the setup steps for a parallel campus cluster in an SF for Oracle RAC environment.

The sample SF Oracle RAC configuration illustrates the configuration procedures with a four-node campus cluster with two nodes at each site. Each node is running SF Oracle RAC 7.3.

Although a Coordination Point (CP) server is not used in the current example, it can also be used instead of a third site for a coordinator disk.
