Planning Cluster Hardware

Language:

The information in this section helps you to plan your hardware for the primary cluster, the secondary cluster, and the intercluster communication.

The Geographic Edition hardware configuration consists of the following elements:

At least two separate clusters that are running Oracle Solaris Cluster software with attached data storage. One of these clusters must be designated the primary cluster.

Note - While you can use a single-node cluster at both the primary and backup sites, a single-node cluster offers no internal redundancy. To ensure no single point of failure, you must have a minimum of two nodes in a cluster at the primary site. You can use a single-node cluster at the secondary site as a cost-effective backup solution if the secondary site is used only for backup purposes and is not for running mission-critical applications.
Internet connections for intercluster management communication between the clusters and for default intercluster heartbeats.
Connections for either host-based or storage-based data replication.
Connections for custom heartbeats, if any.

The Geographic Edition framework supports the same hardware configurations that the Oracle Solaris Cluster product supports. The cluster hardware configurations that use the Geographic Edition framework with storage-based data replication mechanisms must support the related storage hardware. Also, partner clusters must be compatibly configured to support data replication between the clusters.

Internet access is required between partner clusters. The communication between partner clusters for intercluster management operations is through a logical-hostname IP address. The default intercluster heartbeat module also communicates through a logical-hostname IP address.

A cluster in a Geographic Edition partnership conforms to the standard configuration rules of a cluster that is running Oracle Solaris Cluster software.
