Cluster and non-cluster shared storage pool The following illustration shows a configuration where both the clustered and non-clustered servers share storage. This configuration increases reliability and availability through redundancy of the Fibre Channel components, with no single point of failure. Storage is defined for each of the server environments that use the storage partitioning capability of the FAStT500 RAID Controller Enclosure Unit, provided that each server is its own storage subsystem.
