Cabling the Dell|EMC Fibre Channel Storage Systems
This section provides information for connecting your standalone server and cluster server to a storage
system in a direct-attached or in a SAN-attached configuration.
Cabling configuration in a Direct-Attached environment
A direct-attached configuration consists of redundant Fibre Channel host bus adapter (HBA) ports
cabled directly to a Dell|EMC storage system. Direct-attached configurations are self-contained and do
not share any physical resources with other server or storage systems.
Cabling a Stand-alone Server
A server attaches to the storage system using two fiber optic cables with duplex local connector (LC)
multimode connectors that attach to the HBA ports in the server and the storage processor (SP) ports in
the Dell|EMC storage system. These connectors consist of two individual fiber optic connectors with
indexed tabs that must be aligned properly into the HBA ports and SP ports.
NOTICE: Do not remove the connector covers until you are ready to insert the connectors into the HBA port, SP
port, or tape library port.
NOTE: The connections listed in this section are representative of one proven method of ensuring redundancy in
the connections between the server and the storage system. Other methods that achieve the same type of
redundant connectivity may be acceptable.
To cable, do the following steps:
1
Install a cable from a server HBA port 0 to SP-A port FE 0.
2 Install a cable from a server HBA port 1 to SP-B port FE 0.
Figure 1-5 and Figure 1-6 illustrate methods of cabling a server direct-attached to a CX3-20 and CX3-40
storage system, respectively.
NOTE: The cables are connected to the storage processor ports in sequential order for illustrative purposes.
While the available ports in your storage system may vary, HBA port 0 and HBA port 1 must be connected to SP-A
and SP-B, respectively.
