Sun Cluster Geographic Edition Hardware Environment

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

The following additional hardware components form a Sun Cluster Geographic Edition cluster:

• Sun Cluster hardware installations, with attached data storage

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

• Internet connections for inter-cluster heartbeats

• Connections for data replication

• Connections for custom heartbeats

The Sun Cluster 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 3–3 illustrates a high-level view of the Sun Cluster Geographic Edition hardware architecture.
