$$ The system needs to store each server$$s name, brand, IP address, server rooms where the physical servers can be located, and its operating system. Some servers are virtual servers and some are physical servers. If a server is a virtual server, then the system should track which physical server it is running on$.$ A single physical server can host many virtual servers, but each virtual server is hosted on only one physical server. Only physical servers can host a virtual server. In other words, one virtual server cannot host another virtual server. Not all physical servers host a virtual server.
