Clones are duplicate copies of a source LUN. Youcan use snapshots and clones to facilitate backups or to allow multiple hoststo access data without affecting the contents of the source LUN.The source LUN and each snapshot or clone must be accessed from adifferent host or a different cluster.SnapView, which is installed on the storage processors as a non-disruptiveupgrade, can be used in conjunction with MirrorView and is managed fromwithin Navisphere Manager.SAN CopySAN Copy allows you to move data between storage systems without usinghost processor cycles or LAN bandwidth.
