Figure 26: [tf/du] Resource groups and protection group topology

The hardware architecture shown above consists of a dual-node cluster made of SF6900 servers in the primary data center and a single-node cluster in the alternative data center designated for disaster recovery. The storage systems used are Sun StorageTek 9990 systems and data replication is done via Truecopy. Control is via Sun Cluster Geographic Edition. If disaster recovery is not desired, each data center can also be operated independently. In the resource group topology shown above, the active cluster manages a container. The passive cluster is used for disaster recovery purposes. The clusters form a partnership and manage the resource groups in a so-called protection group.
