The figure below is an example of a network topology that contains Dell EMC servers, switches, and other devices. This configuration demonstrates a single rack deployment without any management network. The cloud depicts an existing infrastructure, including spine or core switches, typically found in a data center.
A management network can be constructed before or after a production network is up and running. This is true for console, OOB, and in-band management. For smaller production networks or for existing networks where only one or two additional devices are being installed, it is easy to configure each new device with a direct console cable from a laptop as the device is being added. This is a practical method for providing short-term access to the equipment.
For long-term access to all equipment on a production network, Dell Technologies recommends you implement a management network. The management networks that are described in this guide can be applied to the devices used in the production network. Implementing the management network requires one or more of the following:
- Extra hardware, software, installation, and configuration
- Added configuration of devices being managed
- More cabling
The remainder of this document provides information regarding the various methods for long-term management of the production network.
