Supported Cluster Configurations
Direct-Attached Cluster
In a direct-attached cluster, both nodes of the cluster are directly attached to
a single storage system. In this configuration, the RAID controllers (or storage
processors) on the storage systems are connected by cables directly to the
Fibre Channel HBA ports in the nodes.
Figure 1-1 shows a basic direct-attached, single-cluster configuration.
