Cabling a Multi-Node Cluster to a Dell/EMC Storage System

You can configure a cluster with more than two nodes in a direct-attached configuration using a Dell/EMC storage system, depending on the availability of front-end fibre channel ports. The CX4-120 and CX4-240 storage systems can support up to 6-node cluster, the CX4-480 storage system can support up to 8-node cluster, and the CX4-960 can support up to 12-node cluster.

The following example explains how to cable a four-node cluster:

NOTE: The Dell/EMC storage system requires at least 4 front-end fibre channel ports available on each storage processor.

NOTE: The following steps can be modified to add more clusters or standalone systems.

1Connect cluster node 1 to the storage system:

a Install a cable from cluster node 1 HBA port 0 to the first front-end fibre channel port on SP-A.

b Install a cable from cluster node 1 HBA port 1 to the first front-end fibre channel port on SP-B.
