[Help] How does OpenStack manage and integrate dozens of physical servers?

I am a beginner who has just started working in the data center industry. As a beginner, I have many doubts and questions about the technical aspects. Regarding the OpenStack platform, I am not sure how more than ten or even more servers are managed to enter the platform, including computing nodes, storage nodes, and GPU computing power servers. What technologies can be used to be recognized and managed by OpenStack, or what recommended YouTube tutorials can help me understand these technologies and learn more about related knowledge? Feel free to leave a comment. Thank you very much.

The official doc is your primary research material, also with IA and research engines nowadays you have much information in your hands. First you have to do some basic research about each node function (controller and compute), after that you go to other nodes, like network and storage. Then do some reading on the RabbitMQ topic to learn how the servers communicate. Now you have to start doing some practice, like bringing a small Controller + Compute node up, learn about the setups and installation types based on what you have on hands (small bare metal envirnoment? big cluster with HA? In my example, 2 controller nodes, 1 storage node and the rest of the machines I have available as compute nodes was enough. It may look bad at a first sight, but after some doc reading and IA, videos or other threads in this sub you will have it handled in no time. Good luck!
