1.2.1 Metro Mirror
Metro Mirror provides real-time mirroring of logical volumes between two DS8000 systems
that can be located up to 300 km without an RPQ from each other. It is a synchronous copy
solution where write operations are completed on both copies (local and remote site) before
they are considered to be complete.
