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.
1 Connect cluster node 1 to the storage system:
Install a cable from cluster node 1 HBA port 0 to the first front-end
a
fibre channel port on SP-A.
Install a cable from cluster node 1 HBA port 1 to the first front-end
b
fibre channel port on SP-B.
