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 by Veritas Storage Foundation Cluster File System High Availability (SFCFSHA)

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 SFCFS HA cluster using another database application.

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.
