Live Migration Roles
Live Migrations have two roles: source and destination. These roles determine the active volume that is servicing I/O. The roles can
be swapped one time, either automatically or manually.
In the following examples, the server sends an I/O request that modies the source volume. The changes to the source volume are
replicated to the destination Storage Center over Fibre Channel or iSCSI.
