With the advent of the era of big data, data centers as a link for information transmission, wiring of data centers has become particularly important, and integrated wiring is the basic engineering of data centers. Integrated cabling is relatively concentrated in infrastructure, such as networks, servers, and storage in the data center. Therefore, because the data center stores a large number of network devices, such as network cabinets, servers, cables, etc., in addition to the new requirements for the data center environment, it is also necessary to combine the requirements of the integrated wiring project according to the unchangeable environmental factors. Select the characteristics of the equipment product. For example: Choose a suitable network cabinet.
At present, cabinets have become an indispensable item in the computer industry. Cabinets of various styles can be seen in all major computer rooms. With the continuous breakthrough of the computer industry, the functions of the cabinets are also growing. Cabinets are generally used in network wiring rooms, floor wiring rooms, central computer rooms, data room, control center, monitoring room, monitoring center, etc.
Basic type and structure of the cabinet
The cabinet is generally made of cold-rolled steel or alloy for storing computers and related control equipment. It can provide protection for storage equipment, shield electromagnetic interference, and arrange equipment in an orderly and neat manner to facilitate maintenance of equipment in the future. Cabinets are generally divided into server cabinets, network cabinets, and console cabinets.
Common cabinet colors are white, black, and gray. (There are many types, such as orange, fine sand, etc.); cabinets are divided according to materials, cabinets with aluminum profiles, cold-rolled steel cabinets, hot-rolled steel cabinets; according to the processing technology, there are nine fold profiles Cabinets and 16-fold cabinets.
The type of sheet, the coating material, and the processing technology determine the stability of the cabinet. Generally, its length specification is 600,800mm, width specification is 600,800,1000mm, height specification is 42U, 37U, 22U and so on. Most of the cabinets used in the early days were made of castings or angle steels connected by screws or rivets or welded into a cabinet frame, and a cover plate (door) made of thin steel plate. This type of cabinet is bulky, bulky, and simple in shape, and has been eliminated. Today, cabinet materials are generally made of thin steel plates, steel profiles of various cross-section shapes, aluminum profiles and various engineering plastics. In addition to welding and screwing, the frame of the cabinet is also bonded.
According to the bearing capacity, materials and manufacturing process of the components, the cabinet can be divided into two basic structures: profile and thin plate.
A. Profile structure cabinet: There are two kinds of steel profile cabinets and aluminum profile cabinets. The steel profile cabinet consists of a profiled seamless steel pipe. This cabinet is very rigid and strong enough for heavy equipment. The aluminum profile cabinet consisting of aluminum alloy profiles has a certain rigidity and strength and is suitable for general or light equipment. The cabinet is light in weight, small in processing volume, and beautiful in appearance, and is widely used.
B. Thin-plate structure cabinet: The whole-plate cabinet, the side plate is a whole piece of steel plate bent and formed. This cabinet has good stiffness and strength and is suitable for heavy or general equipment. However, because the side panels are not removable, assembly and maintenance are inconvenient. The structure of the curved column column cabinet is similar to that of the profile cabinet, and the column is bent from a steel plate. This cabinet has a certain rigidity and strength and is suitable for general equipment. Cabinet accessories are also installed in the cabinet as needed. Its main accessories are fixed or retractable rails, locking devices, hinges, wire troughs, cable trays and shielded comb reeds.
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. And the cabinet is gradually becoming one of the protagonists of this change.
Common cabinets can be divided into the following types:
According to the function: fireproof magnetic cabinet, power cabinet, monitoring cabinet, shielding cabinet, safety cabinet, waterproof cabinet, safe, multimedia console, file cabinet, wall hanging 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 chassis cabinet, stainless steel chassis, monitoring console, tool cabinet, standard cabinet, network cabinet.
The server cabinet is in the IDC equipment room. The cabinet is generally referred to as the server cabinet.
For the installation of servers, monitors, UPS and other 19" standard equipment and non-19" standard equipment-specific cabinets, server cabinets, used to assemble panels, plug-ins, subracks, electronic components, devices and mechanical parts and components to form A whole installation box. The server cabinet is composed of a frame and a cover (door), and generally has a rectangular parallelepiped shape and is placed on the floor. It provides a suitable environment and security protection for the normal operation of electronic equipment. This is the first level assembly after the system level. A cabinet that does not have a closed structure is called a rack.
The server cabinet has good technical performance. The structure of the cabinet shall be subjected to the necessary physical design and chemical design according to the electrical and mechanical properties of the equipment and the requirements of the use environment to ensure the structure of the cabinet has good rigidity and strength as well as good electromagnetic isolation, grounding, noise isolation, ventilation and heat dissipation. Performance.
In addition, the server cabinet should be resistant to vibration, shock, corrosion, dust, water, radiation, etc., in order to ensure stable and reliable operation of the equipment. The server cabinet should have good usability and safety protection facilities for easy operation, installation and maintenance, and to ensure operator safety.
Finally, when we are planning a data center that includes servers and storage products, we tend to be overwhelmed by the "fine details" of network cabinets and power supplies, but the system is actually installed and used. These supporting facilities also play an important role in the reliability and stability of the system. From the price point of view, cabinets and racks range from a few thousand yuan to tens of thousands of yuan, which is completely incomparable to the value of internal equipment. Due to the concentration of equipment inside the cabinet, some special "harsh" specifications for the cabinet and the rack are determined. If you do not pay attention to the selection, the troubles caused by the use may be enormous. Therefore, we must select the appropriate network cabinet according to the different characteristics of the cabinet to ensure the normal operation of the built-in equipment of the cabinet, thus ensuring the normal transmission of a large amount of data in the data center.
