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.
Host-Based Replication
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.
Storage-Based Replication
Hitachi TrueCopy, 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
