After you complete the tasks for setting up a replicated data cluster for an application service group, you can optionally create a secondary site for wide area disaster recovery using the SFW HA Global Cluster option (GCO).
With this option, if a disaster affects a local or metropolitan area, data and critical services are failed over to a site hundreds or thousands of miles away.
You can use the Disaster Recovery (DR) wizard when setting up the secondary site. The secondary site is not configured as a replicated data cluster. There can be only one replicated data cluster in the DR environment.
The DR wizard does the following tasks:
Clones the storage
Clones the application service group
Sets up Volume Replicator replication for the secondary site
Configures the primary and secondary site clusters as global clusters
