Geographic Edition Software Environment
Data Replication Configuration
Geographically Distributed Cluster Topology
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.
Three-site configurations (commonly called Three-Data-Center, or 3DC), where the primary is a campus cluster that uses volume manager or storage replication between the campus cluster sites and this primary cluster replicates to a secondary cluster for disaster recovery. For details on these configurations, see Three-Data-Center (3DC) Topologies.
Figure 3-3 illustrates a high-level view of the Geographic Edition hardware architecture.
