1 Introduction
This document illustrates how to configure Dell EMC™ Networking S4148-ON and S4128-ON switches for
use with Dell EMC SC Series storage using Dell EMC best practices.
The host servers and storage controllers can be connected to the switches using the QSFP+ and QSFP28
ports with appropriate breakout cables. The switches are interconnected to each other using 40GbE cables or
100GbE cables.
Optional steps are provided in section 3 to enable Data Center Bridging (DCB).
For more information on SC Series SAN design recommendations, see the Storage Center System Manager
Administrator's Guide and the Storage Center Deployment Guide at the Customer Portal (login required).
