Figure 2-6. Back-End Cabling With Multiple SAS Chains
Cabling the Cluster Nodes and the Compellent Storage Center Front-End
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 storage controller
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 form-factor pluggable
(SFP) module connectors on the Fibre Channel switches and the connectors
on the cluster nodes and storage systems.
