Cabinets are lined up in rows side by side, leaving a certain channel between each column for managers to switch cabinets, put in or put out equipment, while there are two different kinds of air in the channel, they bring the heat generated by the equipment in the cabinet, generally put into the cabinet equipment to ensure front and back ventilation, so that the heat generated by the equipment in the cabinet will be discharged into the channel, there is an inlet at the top of the channel to transfer heat in time. The other side of the cabinet is a cold air channel, cold air is released through the air conditioner and blown into the cabinet, forming an air circulation on the outside of the cabinet to take away the heat generated by the equipment inside the cabinet in time.
Blind should generally be installed in front of the cabinet, need to have heat dissipation holes, which is ignored by most data centers, the blind is like a 'barrier', can effectively prevent cold air directly into the hot channel, resulting in hot and cold alternation, resulting in hot spots, directly improve cooling efficiency. The blind should be placed in the right place so that the administrator can see the operation of all equipment without opening the cabinet door. Some of the cables used in the cabinet should be wrapped around the edge to prevent damage to the cables. Finally, look at the universal feet of the cabinet.
Although the cabinet is generally not easy to move after the cabinet is put away, but occasionally need to move the cabinet, then the universal foot will be useful, now many cabinets have wheel feet, moving will be very convenient, but most or one-way. Therefore, special attention is needed in the selection.
Cabinets within the wiring 'intricate', numerous power lines and data lines entangled together, impeding the flow of airflow, seriously affecting the heat dissipation, so the wiring of various data lines within the cabinet is an important part of the cabinet placement, the cabinet must provide sufficient cable channel, can be from the top of the cabinet, the bottom of the cable in and out, in the cabinet interior, the cable Laying must be convenient, orderly, and equipment cable interface close to shorten the distance of the wiring, reduce the space occupied by the cable, to ensure that the installation of equipment, adjustment, maintenance process, without interference from the wiring, and to ensure that cooling airflow will not be blocked by the cable; at the same time, in case of failure, can be quickly located on the equipment wiring.
Generally there are three methods of wiring in the cabinet: waterfall modeling, forward cable management, and reverse cable management. According to the actual situation of the equipment in the cabinet to choose the wiring method, waterfall modeling is a widely used method in the early data center cabinets, due to this way to install network equipment is easy to destroy the modeling, and even the phenomenon that it is not easy to install network equipment in place, it is rarely used now, forward line management is a commonly used method, the advantage of this method is that in the server room (network area of the mainframe room or weak power room) since Inlet to the wiring frame between all neat, parallel, very beautiful. After all the data lines are connected, the line needs to be marked, the ready instant stickers wrapped around the network cable, and use a pen to mark its use, the logo is required to be simple and easy to understand.
There are many cabinets in the data center that need to be coded and marked for daily management. Whether it is for daily inspection or incident management, the target cabinet can be found quickly. As data centers grow, the role of cabinets becomes more important, giving them more functions. The effective use of these cabinets can effectively reduce the cost of data center operations.
