5 Dell EMC Networking S4248-ON Switch Configuration Guide for Dell EMC Unity, SC Series, and PS Series
iSCSI SANs | SCG4077
1 Introduction
This document illustrates how to configure the Dell EMC™ Networking S4248-ON switch for use with Dell
EMC Unity, Dell EMC SC Series, or Dell™ PS Series storage using Dell EMC best practices.
Link aggregation groups (LAGs) for inter-switch connections are mandatory for PS Series, optional for SC
Series, and not connected for Dell EMC Unity iSCSI SAN environments. If using inter-switch connections, the
switches are interconnected to each other using QSFP28 cables.
Note: For more information on SC Series or PS Series SAN design recommendations, see the Dell EMC
Storage Compatibility Matrix. For information on Dell EMC Unity SAN design recommendations, see the Dell
EMC Unity Simple Support Matrix.
