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.
Note: Factors such as performance and the number of storage partitions influence
the number and type of node.
