Creating a Live Volume
5.2 Proxy data access
An SC Series Live Volume is comprised of a pair of replication enabled volumes: a primary Live Volume and
a secondary Live Volume. A Live Volume can be accessed through either array supporting the Live Volume
replication. However, the primary Live Volume role can only be active on one of the available arrays. All read
and write activity for a Live Volume is serviced by the array hosting the primary Live Volume. If a server is
accessing the Live Volume through uniform or non-uniform paths to the secondary Live Volume array, the I/O
is passed through the Fibre Channel or iSCSI replication link to the primary Live Volume system.
