I'm primarily used to using Computer Towers as basic servers for the company I've been administrating for a while. And we now wish to move away from that to a rack facility. I have no idea (not the slightest clue) as to how these things work. There's just a few questions I would like to ask: Do rack-mounter servers have OS's? Do I configure these servers directly or from another computer? Say for instance I wanted to incorporate a file server making use of a rack mounted server, would it need an OS?
