Let PUE < 1. 1? Inspur pushes the industry's first high-temperature corrosion-resistant server

Abstract: The cooling power consumption of traditional data center remains high, so it is difficult to reduce PUE. Fresh air refrigeration technology may solve the problem of low energy efficiency ratio in data center. Recently, Inspur launched the industry's first high-temperature and corrosion-resistant server-SA 5212E4, which can operate normally at 40℃ and isolate sulfide corrosion, and will help customers build PUE.

With the development of Internet industry and technology, the volume of data center has increased unprecedentedly, but the number of servers in data has reached tens of thousands or even hundreds of thousands. According to the actual operation data, more than 20% of electricity in traditional data centers is used for ventilation and refrigeration, which leads to a high PUE in data centers. At present, most new green data centers at home and abroad are trying to use fresh air refrigeration to dissipate heat for various devices, which will greatly reduce cooling power consumption.

But now the smog is almost normal, and the content of sulfide and nitride exceeds the standard. Direct use of fresh air refrigeration is likely to accelerate the corrosion of electronic components such as server motherboards. As a result, Inspur pioneered the corrosion-resistant server SA 5212E4 in the industry, which promoted the rapid development of fresh air data center technology in China.

High temperature resistance -40℃ without stopping.

The rigorous test data show that Inspur's high-temperature corrosion-resistant server SA52 12E4 can run normally at 40℃ all the year round. The temperature of the traditional computer room is kept below 25-30 degrees Celsius, and air conditioning and refrigeration account for a high proportion of power consumption, which leads to the PUE of the computer room with cold and heat isolation technology being around 1.7, which cannot meet the needs of major Internet customers. Because SA52 12E4 uses more high-temperature resistant components, it can work normally in a worse computer room environment, so the ambient temperature of the computer room can be maintained at about 35 degrees Celsius, which greatly reduces the power consumption of air conditioning and refrigeration, effectively reduces PUE to below 1.3, and greatly reduces TCO.

Limit power consumption-save long-term operating costs

At present, there is a method to realize lossless operation in high temperature environment by strengthening the fan speed. In fact, this form can not only achieve real energy saving, but also reduce the service life of the server. SA52 12E4 completely abandons the low-level practice of sacrificing power consumption for high-temperature environment support, and optimizes the layout of the motherboard, no.

Shadow design, multipoint temperature control; Improve the design of cooling guide cover and air inlet; The components with MTBF of 5 years are preferred, and the weak links of power supply and fan are improved, so that the power consumption of the whole machine is increased by 8% at most relative to the optimal operation at 25℃. Only through high-temperature design support and operation power consumption limitation can the power consumption of the whole machine be controlled, so as to avoid that the saved refrigeration cost is not enough to make up for the increased cost of equipment operation, and the operation cost can be controlled at the server side.

Corrosion-resistant-three-proof coating protection

The surface of SA52 12E4 motherboard adopts the film three-proof coating technology, which has passed GB/T.

2423.5 1-2000 and IEC

60068-2-60 flowing mixed gas corrosion test effectively isolated the motherboard from the air, so that corrosive air could not directly contact the motherboard and refused air corrosion. At the same time, key components, such as power module, SAS card, network card, backplane, etc. Three-proof coating technology is adopted to ensure the corrosion resistance of the whole system, completely reject the corrosion of sulfide and nitride in the air to the equipment and ensure the normal service life.

The corrosion-resistant motherboard is imaged under ultraviolet light.

Low cost-life cycle cost reduction

Inspur SA52 12E4 electronic components are all selected in consideration of high temperature stability and service life. Do not use special parts to increase costs. Corrosion resistant memory and corrosion resistant hard disk are standard. The increase in the cost of the whole machine can be ignored, ensuring that the service life of the server is not affected and the performance is not discounted, so that customers can really afford it, use it, save investment and gain!

After adopting fresh air refrigeration, the refrigeration equipment in the data center can be completely shut down in the season of low temperature from late autumn to early spring. According to the actual test data of Inspur, deploying 9600 high-temperature corrosion-resistant servers in the data center will save more than 4.6 million kWh every year! Inspur SA52 12E4 is the first to appear, which will help customers build PUE.
