Sun Cluster software supports the following methods of data replication between clusters or within a cluster:
Replication Between Clusters – For disaster recovery, you can use host-based or storage-based replication to perform data replication between clusters. Generally, you would choose either host-based replication or storage-based replication, rather than a combination of the two. You can manage both types of replication with Sun Cluster Geographic Edition software.
Sun StorageTek Availability Suite 4, starting with the Solaris 10 OS
Sun StorEdge Availability Suite 3.2.1 on the Solaris 9 OS
In this manual, references to Sun StorageTek Availability Suite software also apply to Sun StorEdge Availability Suite software unless specifically stated otherwise.
If you want to use host-based replication without Sun Cluster Geographic Edition software, see the instructions in Appendix A, Example, Configuring Host-Based Data Replication With Sun StorEdge Availability Suite or Sun StorageTek Availability Suite Software.
Hitachi TrueCopy and Hitachi Universal Replicator, through the Sun Cluster Geographic Edition
EMC Symmetrix Remote Data Facility (SRDF), through the Sun Cluster Geographic Edition
If you want to use storage-based replication without Sun Cluster Geographic Edition software, see the documentation for your replication software.
Replication Within a Cluster – This method is used as a replacement for host-based mirroring.
Application-Based Replication – Oracle Data Guard is an example of application-based replication software. This type of software is used only for disaster recovery. For more information, see the Sun Cluster Geographic Edition Data Replication Guide for Oracle Data Guard
