The Synchronous Mirroring feature provides online, real-time data replication between storage arrays over a remote distance.
What is synchronous mirroring?
Synchronous mirroring replicates data volumes in real time to ensure continuous availability. Storage array controllers manage the mirroring operation, which is transparent to host machines and software applications.
This type of mirroring is ideal for business continuity purposes such as disaster recovery.
How do I configure synchronous mirroring?
You must use the SAN Manager interface to perform the initial mirroring configuration between the arrays. Once it is configured, you can manage mirrored pairs in System Manager.
