How to choose the basic knowledge of data center cabinets

With the development of computer and network technology, the cabinet is becoming an important part of it. IT facilities such as servers and network communication equipment in data centers are developing in the direction of miniaturization, networking, and racking. The cabinet is gradually becoming one of the protagonists in this change. Common cabinets can be divided into the following types:


Divided by function: fireproof antimagnetic cabinet, power supply cabinet, monitoring cabinet, shielding cabinet, safety cabinet, waterproof cabinet, safe, multimedia console, file cabinet, wall cabinet


According to the scope of application: outdoor cabinets, indoor cabinets, communication cabinets, industrial safety cabinets, low-voltage distribution cabinets, power cabinets, server cabinets


Extended classification: console, computer case cabinet, stainless steel case, monitoring console, tool cabinet, standard cabinet, network cabinet


Cabinet – basic type and structure


Common cabinet colors are white, black and gray. (There are many types of data centers, such as orange pattern, fine sand pattern, etc.); the materials of the cabinet generally include aluminum profile cabinets, 10-fold profile cabinets, 16-fold type cabinets, and cold-rolled steel plate Cabinets, as well as hot-rolled steel cabinets.

The steel plate material, coating material, and processing technology determine the stability of the cabinet. Generally, its length is 600, 800mm, width is 600, 800, and height is 42U, 36U, 24U.


Most of the cabinets used in the early days were made of castings or angle steels connected by screws, rivets or welded into the cabinet frame, and then made of cover plates (doors) made of thin steel plates. This kind of cabinet has been eliminated due to its large volume, heavy weight and simple appearance.

With the use of transistors and integrated circuits and the miniaturization of various components and devices, the structure of the cabinet is also developing in the direction of miniaturization and building blocks. The cabinet has developed from the whole panel structure in the past to a series of plug-in data center boxes and plug-in structures with a certain size.

There are two types of assembly and arrangement of subracks and plug-ins: horizontal arrangement and vertical arrangement. Cabinet materials generally use thin steel plates, steel profiles of various cross-sectional shapes, aluminum profiles, and various engineering plastics. The frame of the cabinet is not only welded and screwed, but also bonded.


With the development of data center construction in the direction of overall availability, the demand for cabinet management in the computer room is increasing. It can be foreseen that cabinet solutions that fully meet the needs of data centers and have future scalability will be able to better solve users’ problems and improve the management level of users’ IT systems. Users should consider the following when purchasing cabinets Aspects of factors:


Select the required cabinet type. If you buy it for switches, routers, etc., you should buy a network-type cabinet, which has better wiring troughs; if you buy it for servers, you should buy a server-type cabinet. The effect will be better in comparison. How to distinguish these two cabinets? It can be judged by the cabinet door lock. Of course, this judgment method is suitable for most situations.

The door lock of the server-type cabinet has a groove, and the key can be opened by pressing the groove directly after opening the door; while the door lock of the network-type cabinet has a handle, and the door needs to be turned to open the door after opening the door with the key.


Choose the appropriate size for the cabinet. Before purchasing a cabinet, you must first calculate the size of the computer room space. Next, list all the equipment to be installed in the cabinet and their complete measurement data: length, width, height, and weight.

The overall height of these devices will ultimately determine how much equipment can fit into the rack. Obviously, taller cabinets can hold more equipment and save space. However, the higher the price of the cabinet, the higher the price, so we should not blindly pursue the size of the cabinet, and we should leave a little room for the actual use at this stage.
