This section helps you to adapt the configuration of your Sun Cluster software for the installation of the Sun Cluster Geographic Edition software. This section also helps you to plan the installation of your data replication software.
The Sun Cluster Geographic Edition software must be installed on a cluster that is running the Solaris Operating System and the Sun Cluster software. The Sun Cluster Geographic Edition software configuration is identical to the Sun Cluster software configuration.
The following table lists the required software.
Table 1–1 Required Software
A cluster that is using the 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 StorEdge Availability Suite 3.2.1 software
Hitachi TrueCopy software
EMC Symmetrix Remote Data Facility software
The Sun StorEdge Availability Suite 3.2.1 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. The Sun Cluster Geographic Edition software supports Oracle Real Application Clusters with Hitachi TrueCopy software.
If you use Hitachi TrueCopy RAID Manager software or EMC Symmetrix Remote Data Facility software, the software must be installed on each node of the cluster.
