Selecting the leaf or top-of-rack (ToR) network switches depends on many factors including port speed, media type, cost, and features. Dell Technologies offers a full line of data center switches capable of in-band management for the leaf or ToR switch requirements.

For this example, rack servers, server chassis, and rack power distribution units (PDUs) were connected
