Reviewing the configuration

This configuration example describes the most common configuration, a two-node campus cluster with each node at a separate site.

VCS campus clustering configuration example

The two nodes can be located miles apart and are connected via a single subnet and Fibre Channel SAN. Each node has its own storage array with an equal number of disks and contains mirrored data of the storage on the other array. The example describes a generic database application.

Plan for an equal number and size of disks on the two sites, because each disk group must contain the same number of disks on each site for the mirrored volumes.

The configuration does not include DMP. For instructions on how to add DMP to a clustering configuration:
