In anticipation of an outage (for instance, an approaching hurricane in a coastal region) or after an unplanned outage has occurred, Metro Volume migrates applications, workloads, and data to recovery systems. Metro Volume used in this manner can prevent data loss and minimize application downtime.
Operation: Metro Volume can transparently move volumes from one PowerStore cluster to another. The applications operate continuously. This enables several options for improved system operation and continuous availability:
Migrate the virtual machines using vMotion.
Note: Leveraging Metro Volume for autonomous storage recovery or continuous uptime requires the witness component introduced in PowerStoreOS 3.6.
