A server rack also known as rack mounted server, can be interpreted as a computer dedicated to use as a server and created to be installed in a structure called rack. This rack comprised of multiple mounting slots called bays. Each bay is designed in a way to hold a hardware unit secured in the premise with screws.
A server rack is designed into a cabinet that has standard width size of 19” and 24” (Inches). All kinds of electronics and computing devices come in rack- mounted packages such as servers, telecommunication devices, tape drives, test instruments, and audio and video components. The height of the rack mounted device is expressed in a unit measure, or rack unit, i.e. (1 R.U= 1.75” from top to bottom).
A single rack can encompass multiple servers stacked one above the other, combining the network resources and minimizing the occupied space by the server on the floor. This streamlined configuration also simplifies cabling between the network components.
