Dell CX4 manual Cabling Storage for Your SAN-Attached Cluster

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.

1In 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.

2In 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.

3In 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.

4In 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.
