Analysis of ASUS Main energy-saving technology

With the development of Enterprise Http://www.aliyun.com/zixun/aggregation/32726.html "> informatization construction, the server has become a necessary equipment for many enterprises." and compact, cost-effective 1U rack server in the small and medium-sized enterprises are welcome, but also because of the long-term high load of the operation of many problems caused by trouble. Therefore, how to evade the energy consumption, stability and heat dissipation caused by the space limitation of 1U server is a problem that both enterprise users and server vendors pay attention to. However, server vendors generally have little involvement in this area of independent research and development, most products directly using the Intel design. Asus as one of the few independent research and development of energy-saving technology server manufacturers, its products with stable performance repeatedly won the jackpot, especially 1U server products outstanding energy-saving design performance, but also to many experts and users impressed. How to achieve this outstanding energy-saving design? To meet the broad masses of enterprise users "thirst for knowledge", the author will be the main energy-saving ASUS analysis.

1, Air-through hot air diversion structure

Above, we mentioned that in the Enterprise information platform to build, 1U Rack server because of its small size, high cost performance advantages of many enterprise users. But at the same time, 1U server space is limited, many manufacturers often will hard disk and hard disk, hard disk and optical drive position tightly together, do not consider their ventilation and cooling, for the stability of the server buried a big hidden danger. Because the server often uses a higher CPU frequency, and some are dual-CPU or multiple CPUs, coupled with high speed SCSI hard drives and high-power power supplies, these components emit a large amount of heat, so the air quickly become hot. And the proximity of the space design so that several times the high heat superimposed but not enough space to dissipate heat, will threaten the normal operation of the system, resulting in downtime.

ASUS Business Headquarters Server product director Jianhua points out: A good design, a different structure, is likely to greatly improve the cooling effect of the chassis. If there is a reasonable gap between the high power components, it can achieve good heat dissipation effect.

ASUS Air-through TM Thermal Air diversion structure is precisely through the rational distribution of refrigeration units, the main internal heat source of the server and server chassis mechanism, so that the original server inside the messy heat is standardized management, so that the internal heat quickly outside the machine to ensure that the internal heat of the server does not accumulate, Thus ensuring the long-term operation of the server.

Based on this design concept, ASUS engineers in the design of a very focused on the impact of the chassis structure on the heat, in this detail to do a very detailed research work. Architecture, ASUS server chassis cooling hole is designed to meet the chassis stability requirements, but also to ensure that the largest ventilation area, conducive to the system cooling. Honeycomb structure technology, with a stable structure, the use of materials, wide coverage, high strength and light weight and many other advantages, so long ago widely used in aviation, aerospace and other High-tech fields. ASUS engineers have creatively applied this design to the server chassis heatsink, and honeycomb design is becoming a standard design for it products as a cooling device for the IT industry.

In addition, because the airflow is placed by the hard drive to the end of the chassis into the inside of the case, if the hard disk and the optical drive affixed together, it is equivalent to a tree up a "door", blocking the cold air entry, the heat has a great impact. To this end, Asus deliberately between hard disk and hard disk, as well as the hard drive of the optical drive to leave the appropriate space, and then with the honeycomb vent design, not only easy hard disk and CD-ROM cooling, but also increased air intake. When enough cold air from one end of the hard drive to the center of the "hot big" CPU, ASUS for the CPU equipped with a powerful fan, the relatively low temperature of the atmosphere from the CPU of the copper radiator blown to the chassis of the outlet, forming a smooth flow of air, thereby greatly improving the cooling effect.
