Campus Clusters

Standard Oracle Solaris Cluster systems provide high availability and reliability from a single location. If your application must remain available after unpredictable disasters such as an earthquake, flood, or power outage, you can configure your cluster as a campus cluster.

Campus clusters enable you to locate cluster components, such as cluster nodes and shared storage, in separate rooms that are several kilometers apart. You can separate your nodes and shared storage and locate them in different facilities around your corporate campus or elsewhere within several kilometers. When a disaster strikes one location, the surviving nodes can take over service for the failed node. This enables applications and data to remain available for your users. For additional information about campus cluster configurations, see the Oracle Solaris Cluster 4.0 Hardware Administration Manual.
