Cabling Two Two-Node Clusters to a Dell/EMC Storage System The following steps are an example of how to cable a two two-node cluster. The Dell/EMC storage system needs to have at least 4 front-end fibre channel ports available on each storage processor. 1 In the first cluster, connect 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. 2 In the first cluster, connect cluster node 2 to the storage system: a Install a cable from cluster node 2 HBA port 0 to the second front-end fibre channel port on SP-A. b Install a cable from cluster node 2 HBA port 1 to the second front-end fibre channel port on SP-B. 3 In the second cluster, connect cluster node 1 to the storage system: a Install a cable from cluster node 1 HBA port 0 to the third front-end fibre channel port on SP-A. b Install a cable from cluster node 1 HBA port 1 to the third front-end fibre channel port on SP-B. 4 In the second cluster, connect cluster node 2 to the storage system: a Install a cable from cluster node 2 HBA port 0 to the fourth front-end fibre channel port on SP-A. b Install a cable from cluster node 2 HBA port 1 to the fourth front-end fibre channel port on SP-B. Cabling Storage for Your SAN-Attached Cluster A SAN-attached cluster is a cluster configuration where all cluster nodes that are attached to a single storage system or to multiple storage systems through SAN use a redundant switch fabric. SAN-attached cluster configurations provide more flexibility, expandability, and performance than direct-attached configurations. See "Implementing Zoning on a Fibre Channel Switched Fabric" on page 42 for more information on Fibre Channel switch fabrics. Cabling Your Cluster Hardware 25
