Remote Volume Mirror
Remote Volume Mirror
Remote volume mirror (RVM), an optional feature of SANtricity® Storage Manager software, protects the information stored on your LSI Engenio storage system through real-time data replication to an off-site system.
For each set of volumes that comprise a mirror pair, RVM supports a variety of replication options to provide you with the flexibility to optimize data protection and utilization.
Features
-
Up to 128 mirroring relationships per system
-
Synchronous, asynchronous, and write order consistency mirroring modes
-
Dynamic mode switching without suspending the mirror
-
Suspend/resume with delta resynchronization
-
Secondary volume access
-
Support for cross-mirror data between storage systems
-
Extensive fan-in and fan-out capabilities
Benefits
-
Due to multiple mirroring modes, you can choose the replication method that best meets protection, distance or performance requirements.
-
Dynamic mode switching accommodates changing application and bandwidth requirements without sacrificing protection.
-
Secondary volume access enables the remote data to be utilized prior to a disaster for backup, vaulting, data mining, application testing, etc., without sacrificing protection of the primary site data.
-
Suspend/resume with delta resynchronization reduces vulnerability associated with reestablishing the mirror.
-
Support for cross-mirroring data between storage systems protects the data on both.
-
Storage-based implementation has no host server or application overhead for high performance.
