6 Dell EMC Networking with Isilon Front-End Deployment and Best Practices Guide | version 1.0
However, Dell EMC Networking's legacy OS9 is still prevalent in the industry and supported on a large cross-
section of the currently-shipping portfolio. This document encompasses the use of both operating systems
within the same network architecture.
The Dell EMC S4048-ON will be used as leaf switches, and the Dell EMC Z9100-ON will be used in this guide
as a spine switch. The Dell EMC S3048-ON will be used as a management switch for the iDRAC
connections, out-of-band switch management, as well as the external Isilon connections. Z9100-ON and
S4048-ON leaf pair in rack 1 will utilize Dell EMC Networking OS10EE whereas the S3048-ON and S4048-
ON leaf pair in rack 2 will utilize OS9.
This guide will demonstrate how to utilize Dell EMC Networking, Dell EMC PowerEdge R730xd servers, and
the flexibility of Dell EMC Isilon OneFS in two separate topologies. The examples provided will be using the
Isilon X210. However, all Isilon storage systems utilize OneFS. This allows the steps outlined in this guide to
be used regardless of the hardware that is available.
The first example will highlight the benefits of using the dynamic routing protocol Border Gateway Protocol
(BGP) in a leaf/spine environment. This will be followed up with an example that displays the configuration
and benefits of a layer 2 leaf/spine topology.
While the steps in this document were validated using the specified Dell EMC Networking switches and
operating system(s), they may be leveraged for other Dell EMC Networking switch models utilizing the same
networking OS version or later assuming the switch has the available port numbers, speeds, and types.
Note: For more specific details on deploying a spine-leaf architecture using Dell EMC Networking see Dell
EMC Leaf-Spine Deployment Guide and Dell EMC Networking L3 Design for Leaf-Spine with OS10EE for
more information.
In addition to covering the details of the network configuration, specific configurations within OneFS will be
discussed. The focus will be on the front-end networking configurations, the back-end network that Isilon
utilizes is beyond the scope of this guide. The main configurations discussed within Isilon's OneFS will be as
follows:
• Creation of an Isilon cluster
• Adding additional nodes into the cluster
• Creating an SMB share
• Setting up LACP for each node in the cluster
• The configuration of the SmartConnect feature
