Cabling Storage for Your iSCSI SAN-Attached Cluster

An iSCSI SAN-attached cluster is a cluster configuration where all cluster nodes are attached to a single storage system or to multiple storage systems through a network using a redundant switch fabric.

An iSCSI SAN-attached cluster configuration provides more flexibility, expandability, and performance than a direct-attached configuration.

Figure 2-6 shows an example of a two node iSCSI SAN-attached cluster. Figure 2-7 shows an example of an eight-node iSCSI SAN-attached cluster.

Similar cabling concepts can be applied to clusters that contain a different number of nodes.

NOTE: The connections listed in this section are representative of one proven method of ensuring redundancy in the connections between the cluster nodes and the storage system. Other methods that achieve the same type of redundant connectivity may be acceptable.
