Storage Foundation and High Availability Solutions provides various disaster recovery configurations, such as campus clusters, global clusters for multi-site clusters. In multi-site clusters, the nodes can be placed in different parts of a building, in separate buildings, or in separate cities. The distance between the nodes depends on the type of disaster from which protection is needed and on the technology used to replicate data. Storage Foundation and High Availability supports various replication technologies for data replication.
To protect clusters against outages caused by disasters, the cluster components must be geographically separated.
