|Oracle Solaris Cluster Geographic Edition Security Guide Oracle Solaris Cluster 4.0|
Geographic Edition software is a layered extension of the Oracle Solaris Cluster software. Data replication software enables applications that are running on a Geographic Edition cluster to tolerate disasters by migrating services to a geographically separated secondary cluster. A disaster such as an earthquake, fire, or storm might disable the cluster at the primary site.
If a disaster occurs, the Geographic Edition cluster can continue to provide services by using the following levels of redundancy:
A secondary cluster
Duplicated application configuration on the secondary cluster
Replicated data on the secondary cluster
The Geographic Edition software provides a suite of tools to manage and configure geographically separated clusters with a migration of services between sites. The Geographic Edition software can manage availability across multiple physical locations through robust security, application service migration, and data replication to tolerate disaster across an enterprise system.
