TC and Universal Replicator can share the same pair volumes. Using a combined TC and Universal Replicator configuration can extend disaster recovery options to a third data center.
Like TC, a Universal Replicator pair maintains a copy of the production volume in a second location. However, unlike TC, the Universal Replicator S-VOL is asynchronous, and the secondary system can be located much greater distances from the primary and secondary TC sites.
Creating both a TC and a Universal Replicator backup ensures that a copy in a third location is available in the event that the primary site or one of the systems fails.
Configurations consisting of TC and Universal Replicator pair volumes are covered extensively in the Hitachi Universal Replicator User Guide.
