Data center Energy saving don't let cable affect your heat dissipation

The heat dissipation of the data center generally uses the Heat channel and the Cold channel separation design, namely the hot and cold channel control technology, in order to isolate the hot and cold channel, prevents the hot and cold air to mix, the cold channel helps the equipment to obtain the cold airflow, then passes through the hot channel to expel the hot airflow The network cable itself and the engine room heat dissipation, but not professional wiring is likely to affect the efficiency of heat dissipation. Because cabling is not as standard, data center administrators may be bothered.

Integrated wiring system for the importance of data center, in addition to reflect the impact of its data transmission capacity and space layout, neat network cable is also closely related to the health of the engine room. Not professional wiring technology, in addition to lead to inefficient, but also bring another unexpected problem, that is, heat dissipation.

At present, the heat dissipation of the data center generally uses the hot channel and the Cold channel separation design, namely the hot and cold channel control technology, in order to isolate the hot and cold channel, prevents the hot and cold air to mix, the cold channel helps the equipment to obtain the cold airflow, then passes through the hot channel the hot In this mode, the data center can control the addition of cold air inside the engine room, and slow down the removal of the heat, so as to improve the heat dissipation efficiency. If the computer room management personnel in strict accordance with international standard wiring, for the data center to establish a practical, flexible, scalable integrated wiring system.

Influence of network cable on heat dissipation

The network cable itself and the engine room heat dissipation, but not professional wiring is likely to affect the efficiency of heat dissipation. Because cabling does not follow the standard, data center administrators may be bothered by the following issues:

The walking line in the room is too messy, in the early days, the administrator in order to covet the convenience, did not follow the reasonable wiring scheme, but simply put the new line on top of the old line, over time, the tangled line is hard, not only difficult to clear, but also hinder the channel of hot channels, so that hot and cold exchange can not smoothly. To this end, data centers have to add more equipment (such as fans) to mobilize more energy consumption to solve the problem of heat dissipation.

The network cable cloth to the heat dissipation equipment and vent, which is also an improper way of wiring, will directly affect the heat dissipation, resulting in lower heat dissipation, but also affect the life of the equipment. The cabinet side is equipped with a vent to be used for equipment ventilation, if the cable is piled into the vent, it will plug the ventilation, so the inside of the room becomes extremely muggy, have to use more energy to solve the problem of ventilation, or refrigeration. Neat wiring requires the cable to be tightly arranged on both sides of the equipment, does not affect airflow exchange.

The choice of cable quality is also a problem, the current data center mainstream network cable is six types of network cable, that is, six types of unshielded twisted pair, its performance to meet Tia/eia 568 B2 International standard wiring, and even beyond. Not only good transmission performance, but also in the future can adapt to a long time, do not upgrade prematurely. However, if the first choice of the quality of the general cable, will often lead to future duplication of investment, resulting in line accumulation.
