1Introduction

Dell Networking provides customers with the most efficient use of current networking equipment at the

lowest cost, while still providing today’s great new technologies focused around the explosive data

growth in the industry. The various application demands have driven the need for increased

bandwidth, lower latency infrastructures in today’s networks. Dell EMC’s portfolio covers all these key

areas to provide the best in service and customer experience.

Today’s businesses find it difficult to keep pace with the changing networking and enterprise

landscape. With limited resources, they must support a variety of devices that provide key business

functions, deliver IT services that are reliable and flexible, and provide discernible cost savings.

Networking architecture overview

The Dell PowerEdge FX architecture is a revolutionary approach to shared infrastructure for Enterprise

Computing. It combines the density and innovative agility of hyper-scale computing with the ease of

use and efficiency of advanced management technologies. The FX2 provides a straightforward,

modular approach to infrastructure, and introduces a more practical way to manage the complex IT

needs of businesses.

Zooming in to focus on the data center and storage networking

This deployment guide will provide a step-by-step configuration in the data center utilizing the FN I/O

Module, the PowerEdge FN410S. In this deployment guide, the two FN410S’s installed in the rear of

the FX2 chassis are configured as a virtual link trunk (VLT) pair of switches. This provides the

functionality for the pair of switches to perform as one logical switch

What is VLT?

VLT allows physical links between two switching devices to appear as a single virtual link to other

networking devices. VLT reduces the role of spanning tree protocols (STPs) by allowing link

aggregation group (LAG) terminations on two separate distribution or core switches, and by supporting

a loop-free topology. VLT provides Layer 2 multipathing, creating redundancy through increased

bandwidth, enabling multiple parallel paths between nodes and load-balancing traffic where alternative

paths exist.

2The Dell FX2 and FN I/O Modules

Introducing the Dell FX Architecture, a great way to bring optimized workloads, maximize efficiency

and simplify complexity in today’s data center.

Dell PowerEdge FX2

The Dell FX2 enclosure is unique in its modular capabilities that come in a compact 2U size. This

innovative design combines the density and efficiency of blade servers with the simplicity and cost

benefits of the smaller rack-based server systems.

2.1 FN I/O Modules description

The PowerEdge FX2 is a chassis capable of housing compute, network and storage modules. The

network modules, referred to as one of three FN I/O Modules (FN IOMs), behave as traditional

network switches that are housed in the rear of the FX2 chassis. All three FN IOMs offer network

services for both the Ethernet and storage fabrics in a data center. While the FN410S is used in this

deployment guide, Dell EMC offers three options of FN IOMs providing plug-and-play Ethernet as well

as LAN/SAN convergence with iSCSI and FCoE. In addition to these features, the third model also

offers native Fibre Channel traffic using NPIV Proxy Gateway mode (NPG mode).

2.2 Networking Block FN Series Operational Modes

The FN IOM supports five operational modes: Standalone (SMUX), VLT, Stacking, Programmable

MUX (PMUX) and Full-switch. See Table 1 for detailed descriptions of each mode. To enable a new

operational mode the command stack-unit 0 iom-mode <IOM_Mode>is issued in configuration

mode. After enabling a new operational mode, the switch must be reloaded.

FN Series operational modes

IOM modes and descriptions

IOM mode

Description

Standalone mode (SMUX)

This is the factory default mode for the IOM. SMUX is a fully

automated, zero-touch mode that allows VLAN memberships to be

defined on the server-facing ports while all upstream ports are

configured in port channel 128 and cannot be modified.

VLT mode

In this low-touch mode, all configurations except VLAN membership

are automated. Port 9 is dedicated to the VLT interconnect in this

mode.

Programmable MUX mode

(PMUX)

PMUX mode provides operational flexibility by allowing the

administrator to create multiple LAGs, configure VLANs on uplinks

and to configure DCB parameters on the server-facing ports.

Stacking mode

In Stacking mode, multiple switches can be combined to make a

single logical switch, which is managed by a designated master unit in

the stack. This mode can be useful because it simplifies management

and redundant configurations.

Full Switch mode

In Full Switch mode, all switch features are made available. This mode

requires the most configuration, but allows for the most flexibility and

customization.
