Description

technical field [0001] The invention relates to an Internet data processing center with low energy consumption, belonging to the technical field of data processing. Background technique [0002] With the development and popularization of computer and network technology, the data center, as a unit for centralized installation and operation of computers and networks, has become an independent industry with a complete business model. The data center is the brain and center of the information age. In terms of hardware, It mainly includes the server system and power supply and distribution system in the computer room. [0003] The continuous expansion of the Internet scale requires the continuous expansion of the data processing center, but some shortcomings of the traditional data center limit its development scale to a large extent, which in turn affects the further development of the electronic information industry. Its shortcomings are mainly reflected in the following aspec...

Problems solved by technology

[0004] 1. The power consumption of the mainboard of the server is concentrated in the CPU chip, and the power consumption of a series of equipment such as power conversion, power distribution system, UPS, refrigeration system and transformer will increase for every increase of IW power consumption at the chip level. 2.68-2.84W, so the power consumption of the CPU chip is the key to the overall power consumption of the data center

Traditional server systems mostly use Intel, AMD and other CPUs to increase the main frequency and design complexity to pursue high performance, emphasizing the performance of a single server. Such servers consume a lot of power and cannot meet the current development of higher density and lower power consumption. Require

[0005] 2. Traditional data centers use public grid power supply. Due to the large and concentrated power demand of data centers, and the power supply of two or three circuits, the investment in transformation and power transmission facilities is huge, and the cost of electricity consumption reaches more than 50% of the operating cost of the data center.

[0006] 3. The traditional data center optimizes the power supply quality of the power grid through the centralized UPS system. The centralized UPS system has a huge one-time investment, which is the key point of failure and often the biggest risk point of the data center.

[0007] 4. During the operation of the power supply and distribution system in the traditional data center, the three-phase four-wire AC380V AC power supply needs to perform AC-DC conversion when charging the UPS, and it needs to perform DC-AC conversion when it is transmitted to the computer room. Before the IT equipment is powered, AC-DC conversion is performed. Due to the large number of conversions, the energy loss is relatively large, with an average loss rate of 24%.

[0008] In short, the energy consumption of traditional data centers is too high, and the huge electricity bill has exceeded the one-time infrastructure investment. Designing a new low-energy data center has become a difficult problem for relevant technical personnel in the industry.
