Replication

Policy-based replication can be used to implement high availability and disaster recovery solutions between systems in different locations.

The possible configurations include:
High availability
Active-active high availability between two independent systems.
Disaster recovery
Asynchronous replication to another system for disaster recovery.
High availability and disaster recovery
Active-active high availability between two independent systems, with asynchronous replication to a third system for disaster recovery.
Note: On some platforms, software features, or combinations of software features are limited by available hardware. If applicable, the limitations are documented in a Software feature limits page in the relevant Hardware Guide.
