SAN-Attached Clusters

SAN attached clusters are cluster configurations where redundant Fibre Channel HBAs are cabled to a redundant Fibre Channel switch fabric. Connecting the cluster to the storage system is achieved through the switch fabric. These SAN-attached config- urations can share certain resources with other servers, storage systems, and backup systems on the SAN.

In a SAN-attached cluster configuration, all of the cluster nodes are attached to a sin- gle PowerVault storage system or to multiple PowerVault storage systems through a PowerVault SAN using a redundant Fibre Channel switch fabric. One or more PowerVault Fibre Channel switches make up a Fibre Channel switch fabric.

Figure 10-1 shows an advanced SAN-attached cluster configuration using four-node clustering.
