Introduction 15
Fibre Channel Switch Module
The Fibre Channel switch module provides a switched connection between
the Fibre Channel daughter card in the server modules and a supported Fibre
Channel device. The switch module functions as a director, mapping requests
and responses between the interconnected devices.
Additionally, the Fibre Channel switch module includes an internal serial port
that communicates with the DRAC/MC module.
The Fibre Channel switch module supports the following configurations:
• Network-attached configuration with up to two supported Dell|EMC
storage systems
• Network-attached connection to an external storage area network (SAN)
with up to four supported Dell|EMC storage systems
Fibre Channel Pass-Through Module
The Fibre Channel pass-through module provides a direct connection between
the Fibre Channel daughter card in the server modules and a supported Fibre
Channel device. The pass-through module functions as a dedicated link
between the server modules and specific ports on the pass-through module.
The pass-through module supports the following configurations:
• Direct-attached configuration to a supported Dell|EMC storage system
• Network-attached connection to an external SAN with up to four
supported Dell|EMC storage systems
Table 1-3 summarizes the supported Fibre Channel module configurations.
