1 Introduction Dell EMC OS 10.4.2 introduces another storage solution enhancement – Fibre-Channel over Ethernet with VLT – This enhancement provides the necessary resilience needed for a robust storage over ethernet where traditional FCoE connectivity over redundant links was not possible. 1.1 Objective This document provides a set of valid Dell EMC networking configurations that apply to a typical FCoE deployment scenario over redundant links providing storage connectivity resiliency. 1.
2 Setup Figure1 shows the reference setup used in the lab to demonstrate the FCoE port pinning over redundant Ethernet links. Starting from the end host, two LAGs or port-channels have been created. Each LAG has two links from the end host (R720 server). LAG_1 connects to S4148U-02, and LAG_2 connects to S4148U-03.
2.1 Deployment components The setup consists of three devices: 7 FC Switch (S4148U-04) ToR_1 (S4148U-02) – FSB (FIP Snooping Bridge) ToR_2 (S4148U-03) – FSB (FIP Snooping Bridge) Dell EMC OS10 FCoE with Redundant Links Configuration Cheat Sheet | 1.
A Device Configuration Details A.1 Configuration of S4148U-04 (FC and Ethernet Switch). S4148U-04 is providing both Fibre-Channel and standard Ethernet services. Two vlans are configured on this switch (Vlan 1001, and 100). 1. Enable the fibre-channel feature on the switch and create a domain. mk-S4148U-04# conf t mk-S4148U-04(config)# feature fc domain-id 1 mk-S4148U-04(config)# end mk-S4148U-04# 2. Create the respective FC zones.

Configure the vfabric and activate the FC zone. The vfabric construct is a virtual fabric for a specific zone. Vlan 1001 is the FCoE vlan and the fcoe map is a unique MAC address prefix used by the FC switch to identify FCoE traffic.
interfaces or links towards the FSB switches will be configured as the pinned port or dedicated link towards the FC target.
