|Oracle Solaris Cluster Geographic Edition Overview Oracle Solaris Cluster 4.1|
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.
