Cabling a SAN-Attached Cluster to a Dell | EMC Storage System
The supported Dell | EMC storage systems are configured as follows:
CX200 — One DPE, one DAE2 enclosure, and two SPSs
CX400 — One DPE, one or more DAE2 enclosures, and two SPSs
CX600 — One SPE, at least one DAE2 (or DAE2-OS) enclosure, and two SPSs
The cluster nodes attach to the storage system using a redundant switch fabric and fiber optic cables with duplex LC
multimode connectors.
The switches, the HBAs in the cluster nodes, and the SP ports in the storage system use duplex LC multimode connectors.
The connectors consist of two individual fiber optic connectors with indexed tabs that must be inserted and aligned properly in
the small form-factor pluggable (SFP) module connectors on the Fibre Channel switches and the connectors on the cluster
nodes and storage systems.
See " Fibre Channel Cable Connectors " for more information on the duplex LC multimode fiber optic connector.
Each HBA is cabled to a port on a Fibre Channel switch. One to four cables connect from the outgoing ports on a switch to a
storage processor on a Dell | EMC storage system.
Table 5-2 provides information for cabling your storage system to the Fibre Channel switch.
