The disaster recovery framework hardware configuration is the basis for a disaster recovery framework cluster.
The following additional hardware components form a disaster recovery framework cluster:
Disaster recovery framework 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 disaster recovery framework 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
Data Replication From a Two-Node Cluster to a Two-Node Cluster illustrates a high-level view of the disaster recovery framework hardware architecture.
