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
l
Coordination of the configuration of Storage Mirroring Recover and
other applications can be more complex than the one-to-one
active/standby configuration.
l
During replication, each server must continue to process its normal
workload.
l
Administrators must avoid selecting a target destination path that is
included in the source’s replication set. Any overlap will cause an
infinite loop.
l
To support the production activities of both servers during failover
without reducing performance, each server should have sufficient disk
space and processing resources.
l
Failover and failback scripts must be implemented to avoid conflict with
the existing production applications.
l
You must pause the server when backing up database files.
