The Oracle Solaris Cluster Disaster Recovery framework is a layered extension of the Oracle Solaris Cluster software. Data replication software enables applications that are running on a Disaster Recovery partner 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 partner 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 Disaster Recovery framework provides a suite of tools to manage and configure geographically separated clusters with a migration of services between sites. The clusters can be global clusters, zone clusters, or a combination of both. The Disaster Recovery framework can manage availability across multiple physical locations through robust security, application service migration, and data replication to tolerate disaster across an enterprise system.
