administrator. With the software products described here, the requirements with respect to
visualization and flexibilization of containers right up to disaster recovery concepts can be covered
completely.
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.
