Planning the Data Replication Software

A cluster that is using Sun Cluster Geographic Edition software with a data replication product is subject to the standard configuration rules of a cluster that is running the data replication product with Sun Cluster software. Partner clusters must have compatible software configurations to support data replication between the clusters.

The Sun Cluster Geographic Edition product supports the following data replication products:

• Sun StorageTek Availability Suite software.

• Hitachi TrueCopy software.

• EMC Symmetrix Remote Data Facility software.

The Sun StorageTek Availability Suite software is a host-based replication method. This method consists of software installed on a host that controls replication from one server to a secondary server.

The Hitachi TrueCopy and EMC Symmetrix Remote Data Facility replication use a storage-based method. These methods use replication that is built into the storage hardware.

If you use Hitachi TrueCopy RAID Manager software or EMC Symmetrix Remote Data Facility software, you must install the software on each node of the cluster.
