One-to-one, active/active

Description

Each server acts as both a source and target actively replicating data to each other.

Applications

This configuration is appropriate for failover and critical data backup. This configuration is more

cost-effective than the Active/Standby configuration because there is no need to buy a dedicated target

server for each source. In this case, both servers can do full-time production work.

Considerations

Coordination of the configuration of Storage Mirroring and other applications can be more complex

than the one-to-one active/standby configuration.

 During replication, each server must continue to process its normal workload.

 Administrators must avoid selecting a target destination path that is included in the source’s

replication set. Any overlap will cause an infinite loop.

 To support the production activities of both servers during failover without reducing performance,

each server should have sufficient disk space and processing resources.

 Failover and failback scripts must be implemented to avoid conflict with the existing production

applications.
