A rack diagram is the most useful type of network documentation for visually representing the physical arrangement of devices within server racks. It provides detailed information about the exact placement of hardware, aiding in both troubleshooting and future expansions or modifications. Physical diagrams show the physical connections between devices, not specifically how they are arranged in racks. Network diagrams provide a broader overview of connections and network topology, which does not detail specific device placements in server racks. Cable maps focus primarily on the routing and organization of cables, not on device placement within racks.
