Deployment Guide

13 Dell EMC Networking FCoE-to-Fibre Channel Deployment with S4148U-ON in F_port Mode | version 1.0
3.3 OOB management network
The out-of-band (OOB) management network is an isolated network for management traffic only. It is used by
administrators to remotely configure and manage servers, switches, and storage devices. Production traffic
initiated by the network end users does not traverse the management network.
An S3048-ON switch is installed at the top of each rack for OOB management connections as shown.

OOB management network connections
Four 10GbE SFP+ ports are available on each S3048-ON switch for use as uplinks to the OOB management
network core. Downstream connections to servers, switches, and storage devices are 1GbE BASE-T.
The dedicated OOB management port of each leaf and spine switch is used for these connections. Each
PowerEdge R640 server has two connections to the S3048-ON: the server’s iDRAC port and a 1GbE NIC
that is used for ESXi host management.
Note: For this deployment example, each server’s ESXi management connection is made using one of the
two QLogic 57800 1GbE BASE-T ports on the rNDC.
The Unity 500F storage array has two dedicated management ports: one for SP A and one for SP B. Both are
connected to the S3048-ON.
