Use the mirroring features to replicate data between a local storage array and a remote storage array, either asynchronously or synchronously.
What is mirroring?
DE Series applications include two types of mirroring — asynchronous and synchronous. Asynchronous mirroring copies data volumes on demand or on a schedule, which minimizes or avoids downtime that might result from data corruption or loss. Synchronous mirroring replicates data volumes in real time to ensure continuous availability.
How do I configure mirroring?
You configure asynchronous or synchronous mirroring in SAN Manager, and then use System Manager to manage synchronizations.
