9 Dell EMC Networking Fibre Channel Deployment with S4148U-ON in F_port Mode | version 1.0

3 Topology overview

Each S4148U-ON provides universal ports that may be configured as either FC or Ethernet. The mix of FC

and Ethernet ports allows the switches to simultaneously connect directly to an FC SAN for storage traffic and

act as leafs in a leaf-spine network for production TCP/IP traffic.

Note: FC SAN traffic does not traverse the leaf-spine network, or the VLT interconnect (VLTi). FC traffic is

contained within the rack.

A combined FC SAN and leaf-spine topology is shown in the diagram below.

Combined FC SAN and leaf-spine topology

Note: Using a leaf-spine network in the data center is considered a best practice. This document covers

configuration of the FC SAN portion of the topology above. For the leaf-spine Ethernet portion, refer to Dell
