Data center expert Wang and Chuihai on energy system model of China data Center

December 11, at the DCD 2012 meeting held at the Renaissance Beijing Capital Hotel, Tencent Data Center chief architect Wang and data Center Working Group data Center consultant Chuihai and delegates discussed the energy system model of China data Center in depth. In the keynote speech, the two experts described the energy consumption of data centers as energy-intensive facilities, reviewed the current status of China's data center industry, especially energy consumption, and creatively proposed http://www.aliyun.com/zixun/aggregation/8313. HTML ">spider model, and explores the future way of adopting innovative energy model in China, and obtains the widespread attention of the audience."

The data center is a high-energy information infrastructure, two experts say. According to statistics: Typical data center power of about 1 million watts, some even more than 20 million watts, power consumption accounted for the overall cost of data center more than 50%. Relevant data show: From 2000 to 2006, the computational performance increased by 25 times times, but the energy efficiency was only increased by 8 times times, the energy consumption of 1000 dollars per server increased by 4 times times, currently the cost of power and data center ancillary facilities has exceeded the costs of purchasing IT equipment.

When it comes to energy efficiency in China's data centers, the two experts first reviewed China's data center industry in its entirety. They cited statistics: China has now built more than 500,000 data centers, and expects to build 540,000 data centres by the end of 2012. 2011 Its application market size reached 102 billion yuan, the annual composite growth rate will reach 18.6%.

Two experts also pointed out: at present the domestic data center mainly by the operator IDC and the enterprise and the government Unit's EDC composition, its energy consumption scale is close, but the quantity EDC far more than IDC, the intensive benefit is very low. At present, the three major telecom operators: China Telecom, Chinese Unicom, and China Mobile are the main builders of IDC, the Internet Data Center, by 2011, Telecom has been able to provide more than 30,000 cabinets, Unicom can provide more than 20,000 cabinet.

They point out that the current situation of domestic data centers can be summed up by the words "small, loose and low": The domestic 100~1000㎡ data centers account for only a small portion of the total data center, and the locations are scattered, many of which are in business and government offices, IDC, the Internet User Data center, is mainly distributed in chinanet eight backbone nodes and more than 30 provincial nodes; At present, domestic data center availability level is generally low, mostly B class (T2) level, at the same time Pue higher, in 2.5~3 around.

In terms of energy consumption and efficiency in China's data centers, two experts point out: China's data center consumes 2% of the total power consumption of the whole society, or 10% of the total energy consumption of the whole country, equivalent to the annual capacity of the Three Gorges Dam; however, the pue of China's typical data centers is only 2.2~3.0, far above the world average, And the utilization rate is only 20%~30%. In a typical managed data center in China, the average four-year electricity charge will exceed the data center infrastructure investment, and the data center life can reach more than 15 years.

on how to improve the efficiency of the data center, the two experts pointed out: the Power/electromechanical, HVAC/refrigeration, energy three levels of overall optimization. For the Pue metrics currently widely used in the industry, they argue that it is not enough to measure the energy efficiency of data centers in the cloud computing era, that green data centers need to focus not only on TCO, but also on the data center's life-Cycle Emissions index Facility and infrastructure are combined to consider the construction and operation of the system.

To this end, the two experts creatively proposed the spider model. The spider model is a model of the data center industry using an industry system consisting of the initials of six English words (S=saas, P=paas, I=iaas, D=data Center, e= Energy, R=resource). When using the spider model to talk about the development of China's data center, they focused on the relationship between energy and data center construction, and analyzed the current situation of power supply of "nest electricity" and "electricity shortage" in China: Northeast power Grid and Inner Mongolia power supply surplus, while Southern power grid is short of power supply.

In the new energy development and construction, the two experts introduced the world's largest scenery storage joint power generation project-the National Grid Zhangbei demonstration project. Project planning and construction of wind power 500,000-kilowatt, PV power generation 100,000-kilowatt, energy storage device 110,000-kilowatt. One phase of the planning and construction of wind power 100,000-kilowatt, PV 40,000-kilowatt, energy storage 20,000-kilowatt, supporting the construction of 220,000 kv intelligent substation. The current phase of the acceptance of the grid.

In the energy-building model, the two experts made the following recommendations:

– City (Grid +CCHP)

– Outer suburbs (cchp+ power grid)

– Wilderness (wind power +cchp+ grid)

– Data Center type

– City Data Center main DC Private Cloud

-Outer-Suburb data center standby/double Live hybrid cloud

– Wilderness Data Center disaster recovery/backup public cloud

In the development of new energy, the two experts reviewed the attempts by the IT giants, such as Microsoft, HP and Apple, to use methane power and to wind power, pointing out that the data center is still out of power and that natural gas is more reliable than the biogas supply. He pointed out: in the process of exploring the road of energy construction in China's data center, we need to consider the particularity of China's energy policy, and the 1000 distributed energy projects launched in China during 35 will bring opportunities for the development of China's data center industry.
