Storage Center Replications and Live Volumes
A replication copies volume data from one Storage Center to another Storage Center to safeguard data against local or regional data
threats. A Live Volume is a replicating volume that can be mapped and active on a source and destination Storage Center at the same time.
To perform replications, a Remote Instant Replay (Replication) license must be applied to the source and destination Storage Centers.
To create a Live Volume from a replication, a Live Volume license must be applied to the source and destination Storage Centers.
NOTE: The Live Volume feature is not supported on storage systems with front-end SAS connectivity.

Storage Center Replications
A Storage Center can replicate volumes to a remote Storage Center and simultaneously be the target of Replication from a remote Storage
Center. Using Storage Manager, an administrator can set up a replication plan for Storage Centers that supports an overall Disaster
Recovery strategy.
In the following example, a server sends an I/O request that modies the source volume. The changes to the source volume are replicated
to the destination Storage Center over Fibre Channel (FC) or iSCSI.
