Geographic Edition Hardware Environment

The Oracle Solaris Cluster hardware configuration is the basis for a Geographic Edition cluster.

The following additional hardware components form a Geographic Edition cluster:

• Oracle Solaris Cluster hardware installations, with attached data storage

• Internet connections for inter-cluster management communication between the Oracle Solaris Cluster installations

• Internet connections for inter-cluster heartbeats

• Connections for data replication

• Connections for custom heartbeats

The Geographic Edition hardware environment supports the following topologies:

• N+1, where multiple clusters that are located at multiple sites are communicating with a single backup cluster

• Cluster pair, where both clusters are online and providing services

Figure 3-2 illustrates a high-level view of the Geographic Edition hardware architecture.
