Deployment Guide

10 Dell EMC Networking Fibre Channel Deployment with S4148U-ON in F_port Mode | version 1.0
3.1 FC SAN topology detail
Each S4148U-ON switch is placed in F_port mode and acts as an FC switch. This enables direct connections
to N_port devices such as FC storage and server FC HBAs without the need for additional dedicated FC
switches.
The FC SAN topology used in this guide is shown in Figure 7.

FC SAN topology
Each PowerEdge R640 server in this deployment contains one QLogic QLE2662 FC HBA with two 16Gb FC
ports. Each HBA port is connected to an FC port on one S4148U-ON as shown.
The Unity 500F storage array contains redundant storage processors, SP A and SP B. 16Gb FC ports from
the Unity SPs are directly connected to FC ports on the S4148U-ON switches as shown.
