Live Volume use cases
101 Dell EMC SC Series: Synchronous Replication and Live Volume | CML1064
The requirements for this operation include the following:
• Server(s) properly zoned into both SC Series arrays
• Server(s) configured on both arrays
• Stretched Layer 2 networking between source and destination sites or hypervisors
• 1 Gbps or better low-latency iSCSI or Fibre Channel connectivity between the arrays to support
asynchronous or synchronous Live Volume replication
11.3 Disaster avoidance and disaster recovery
In anticipation of an outage (for instance, an approaching hurricane) or after an unplanned outage has
occurred, Live Volume migrates data and applications to recovery systems. Live Volume used in this manner
can prevent data loss and application downtime.
Operation: Live Volume can transparently move volumes from one SC Series array to another. The
applications operate continuously. This enables several options for improved system operation:
• Redefine remote site as primary for all volumes on local site
• Shut down applications on local site
• Restart or recover applications on remote site
• Move applications seamlessly back to their original locations using Live Volume
