Cabling Your Cluster Hardware 25
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.
