4.2 OOB management network The out-of-band (OOB) management network is an isolated network for remote management of servers, switches, and storage devices via their dedicated hardware management ports. It is also commonly used to carry heartbeat messages sent between switches configured as VLT peers. For OOB management connections, one S3048-ON switch is installed in each rack as shown: OOB Management Network Rack 1 S3048-ON Rack 2 S3048-ON Rack 3 S3048-ON Rack n S3048-ON Leaf Switch 1A Leaf Switch 1B Leaf Switch 2A Leaf Switch 2B Leaf Switch 3A Leaf Switch 3B Leaf Switch nA Leaf Switch nB VxRail Node Cluster 1 VxRail Node Cluster 1 VxRail Node Cluster 1 VxRail Node Cluster 1 VxRail Node Cluster 2 VxRail Node Cluster 2 VxRail Node Cluster 2 VxRail Node Cluster 2 OOB management network connections VxRail Node Cluster 3 VxRail Node Cluster 3 VxRail Node Cluster 3 PowerEdge Server Spine Switch 1 Spine Switch 2 PowerEdge Server Storage Array Note: This guide focuses on the devices in Rack 1. Devices shown in other racks are for illustration only. 1GbE BASE-T ports on each S3048-ON are connected downstream to hardware management ports on each device. This includes VxRail node iDRACs, PowerEdge Server iDRACs, and dedicated management ports on switches and storage arrays. Four 10GbE SFP+ ports are available on each S3048-ON for use as uplinks to the OOB management network core. Note: This is not to be confused with the in-band management network which runs on the same physical network as other VxRail and end-user traffic. In-band connections are covered in Section 3. Devices on the OOB management network in this guide use the 100.67.0.0/16 IP address block. 14 Dell EMC Networking OS10 Enterprise Edition Switch Configuration Guide for VxRail 4.5
