Data Replication Configuration
You can use a campus cluster for the primary cluster and a secondary cluster for disaster recovery, which creates a three-site or three–data–center (3DC) configuration of primary, backup, and disaster recovery sites.
There are two ways to perform 3DC replication:
Use volume-manager mirroring within the campus cluster. Use Sun StorageTek Availability Suite or use application-based replication, such as Oracle Data Guard or MySQL software replication, to the disaster recovery site.
Use storage-based replication within the campus cluster, such as EMC Symmetrix Remote Data Facility or Hitachi TrueCopy and Universal Replicator. Use application-based replication, such as Oracle Data Guard or MySQL software to replicate the application from the campus cluster to a disaster recovery site.
You cannot create a daisy chain of Geographic Edition pairs (for example, London-Paris-Rome) for the same managed application.
