Extended Remote Advanced Copy

Extended Remote Advanced Copy uses a combination of a Fibre Channel switch and WAN converter to support very long distances over WAN. Replicated data can be located at a remote site hundreds of kilometers away from the primary site. This provides high security for the protection of critical data from both man-made and natural disasters.
