One-to-One, Active/Active

Description

Each machine 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

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

Considerations

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

than the Active/Standby configuration.

! During replication, each machine 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 machines during failover without reducing performance,

the failover target machine should have sufficient disk space and processing resources.

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

applications.
