Cabling a SAN-Attached Cluster to a Dell/EMC Storage System
The cluster nodes attach to the storage system using a redundant switch fabric and Fibre optic cables with duplex LC multimode connectors.
The switches, the HBA ports in the cluster nodes, and the SP ports in the storage system use duplex LC multimode connectors. The connectors consist of two individual fibre optic connectors with indexed tabs that must be inserted and aligned properly in the small
Each HBA port is cabled to a port on a Fibre Channel switch. One or more cables connect from the outgoing ports on a switch to a storage processor on a Dell/EMC storage system.

Attach one cable from each storage processor port to the Fibre Channel switch.
NOTE: Adding more cables from the storage system to the switches can increase the I/O bandwidth and high availability of data. Although the
