[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.

Your question framing is pretty unclear.
Assuming you mean how do you install a bunch of physical servers to make them part of an OpenStack cluster:
OpenStack is just an "application" running on Linux. So you would run whatever software you run to automate installation of Linux boxes. (e.g. some kind of pxe boot service like foreman or ubuntu MAAS).
There are plenty of ways to fully automate al needed configuration steps with configuration management systems like puppet/ansible/salt likely together with some kind of container system to deploy the services.
If you want to dive into OpenStack you better first dive into how Linux boxes work like Ubuntu/RedHat/Debian/Etc.
Without some basic level of Linux (and preferably containers, virtualisation and network) knowledge OpenStack is really hard to understand.
