Components

Continuous Access XP operations involve the XP12000/XP10000 at a primary and secondary (remote)
site, physical communications paths between these disk arrays, and Command View XP or XP Remote
Web Console. Continuous Access XP copies online data at the primary site to volumes at the secondary
site via dedicated Fibre Channel remote copy connections.
Host failover software is required for effective disaster recovery with Continuous Access XP.

XP12000/XP10000

Continuous Access XP operations involve primary (main) disk arrays and secondary (remote) disk arrays
(MCUs and RCUs). This document describes Continuous Access XP operations in which the main disk array
is an XP12000/XP10000 and the remote disk array is an XP12000/XP10000. MCUs contain
Continuous Access XP primary volumes (P-VOLs), which contain original data and are online to the hosts.
RCUs contain Continuous Access XP secondary volumes (S-VOLs), which are synchronous or asynchronous
