Continuous Access XP Journal operations involve local arrays at the primary and secondary sites, physical
communications paths between these arrays, and Command View XP or XP Remote Web Console.
Continuous Access XP Journal copies the original online data at the primary site to backup volumes at
the secondary site through dedicated Fibre Channel remote copy connections using a journal volume.
You can operate Continuous Access XP Journal with the user-friendly GUI environment using Command
View XP or XP Remote Web Console.
NOTE:
Host failover software is required for effective disaster recovery with Continuous Access XP Journal.
