The digital economy is becoming a key force in reorganizing factor resources, reshaping the economic structure, and improving market competitiveness. Digital industrialization and industrial digitization are important directions for my country's economic transformation and upgrading. In recent years, with the acceleration of digital transformation and upgrading in various industries, especially the rapid popularization and application of new technologies such as 5G, artificial intelligence, and the Internet of Things, the total amount of data in the whole society has exploded, and the demand for data storage, calculation, transmission, and application has increased significantly. To improve, there is an urgent need to promote the rational layout of data centers, optimize supply and demand, green intensification and interconnection, and build a new computing power network system that integrates data centers, cloud computing, and big data.
Relevant research reports show that for every 1 percentage point increase in the computing power index, the digital economy and GDP will grow by 3.3‰ and 1.8‰ respectively. At present, the construction of computing power infrastructure represented by data centers, supercomputing centers, etc. is accelerating and is becoming an important base to support the development of the digital economy. According to statistics, the average annual growth rate of my country's data increment exceeds 30%.
On January 12, the State Council released the "14th Five-Year Plan for Digital Economic Development." As the first five-year plan for the digital economy, the plan proposes that during the "14th Five-Year Plan" period, my country's digital economy will shift to a new stage of deepening application, standardized development, and universal benefit and enjoyment. We will build data center clusters, accelerate the implementation of the “digital data in the east and calculate in the west” project, and continue to promote the construction of green digital centers.
As a key node in the "East-to-West Computing" project, the national hub node of the National Integrated Computing Power Network is the backbone node of my country's computing power network. Within the national hub node, several data center clusters are gradually planned and developed.
In addition to the four national data center clusters released in January 2022: the Helinger cluster in the Inner Mongolia hub, the Gui'an cluster in the Guizhou hub, the Qingyang cluster in the Gansu hub, and the Zhongwei cluster in the Ningxia hub , this time the National Development and Reform Commission and other departments released 6 more national data center clusters, namely the Zhangjiakou cluster located in the Beijing-Tianjin-Hebei hub, the Yangtze River Delta ecological green integrated development demonstration zone cluster located in the Yangtze River Delta hub, and the Wuhu cluster located in The Shaoguan cluster is located in the Guangdong-Hong Kong-Macao hub, and the Tianfu cluster and Chongqing cluster are located in the Chengdu-Chongqing hub. These 10 clusters have clear geographical boundaries, provide sufficient policy guarantees and supporting facilities, and support the construction of large and ultra-large data centers in various industries within the clusters. Establish a high-speed data center direct network between clusters.
The eastern part supplies "numbers"
The west counts "numbers"
Like the "West-to-East Gas Transmission" and other projects, it is necessary to realize "numbers from the east and numbers from the west" , it is also necessary to establish transmission facilities such as high-speed broadband and conduct a reasonable layout in hub nodes. In May 2021, the National Development and Reform Commission, the Central Cyberspace Administration of China, the Ministry of Industry and Information Technology, and the National Energy Administration released the "Implementation Plan for the Computing Power Hub of the National Integrated Big Data Center Collaborative Innovation System" (hereinafter referred to as the "Implementation Plan"), clearly proposing the layout and construction The national hub node of the national computing power network, accelerating the implementation of the "Eastern Data and Western Calculation" project, and building a national computing power network system.
The "Implementation Plan" clarifies the regions where the national hub nodes of the national integrated computing network will be laid out, including the Beijing-Tianjin-Hebei region, the Yangtze River Delta, the Guangdong-Hong Kong-Macao Greater Bay Area, Chengdu and Chongqing, as well as Guizhou, Inner Mongolia, Gansu, Ningxia and other 8 regions.
Enter the data center area, stand outside the corridor, and look at the computer room through the glass. The densely packed servers are operating efficiently, and robots shuttle through them for real-time inspection... Huawei Cloud Guian Data is located in Gui'an New District, Guizhou. The center will be officially put into commercial use at the end of 2021. This is also the largest data center in the history of Huawei Cloud and will reach 1 million servers in the future. In recent years, Guizhou has taken the lead in deploying new digital infrastructure by leveraging its advantages in climate, energy, geology and other aspects. Today, there are seven ultra-large data centers in Gui'an New District alone. The national strategy of “numbering from the east to the west” has brought new opportunities to Guizhou.
In December 2021, the National Development and Reform Commission and other departments responded in the "Reply Letter on Agreeing to Guizhou Province to Launch the Establishment of a National Hub Node for a National Integrated Computing Power Network", focusing on the Gui'an National Data Center Cluster. We will seize the opportunity to optimize inventory and improve resource utilization efficiency, focusing on supporting the Yangtze River Delta, the Guangdong-Hong Kong-Macao Greater Bay Area, etc., and actively undertaking the computing power needs of the eastern region. The reply letter clarified that the Gui'an National Data Center Cluster should promptly complete the construction goal of the starting area: the average data center availability rate should not be less than 65%. The power utilization efficiency of the data center is controlled below 1.2, and the utilization rate of renewable energy is significantly increased.
The relevant person in charge of the High Technology Department of the National Development and Reform Commission recently responded to questions about the construction and layout of national computing power hub nodes, saying that the layout and construction of two batches of 8 nodes have different positioning and different roles. different.
Specifically, the four nodes of Guizhou, Inner Mongolia, Gansu, and Ningxia will build non-real-time computing power support bases for the whole country. It is positioned to continuously improve the quality and utilization efficiency of computing power services, give full play to its resource advantages, consolidate basic guarantees such as networks, and actively undertake nationwide non-real-time computing power needs such as back-end processing, offline analysis, and storage backup. The four nodes of Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong-Hong Kong-Macao Greater Bay Area, and Chengdu-Chongqing must serve the implementation needs of major regional development strategies. It is positioned to further coordinate the layout of data centers in and around the city, achieve coordination and sustainability of large-scale computing power deployment with land, energy, water, electricity and other resources, optimize the data center supply structure, and expand the space for computing power growth.
“Just like the ‘South-to-North Water Diversion Project’ and ‘West-to-East Power Transmission Project’, we must give full play to the advantages of our country’s institutional mechanisms, integrate and coordinate the layout from a national perspective, optimize resource allocation, and improve resource use efficiency.” Sun Wei said.
Continuously optimize the data center
Energy usage efficiency
The implementation of the “number in the east and calculate in the west” project is inseparable from the goal of green intensification. It is worth noting that while data centers support the rapid development of the digital economy, it cannot be ignored that because data centers require a large amount of power to maintain the operation of servers, storage equipment, backup devices, cooling systems and other infrastructure, energy consumption and carbon emissions are growing rapidly. .
The "Green Data Center White Paper 2020" released by the China Electronics Technology Standardization Institute pointed out that in recent years, the energy efficiency level of my country's data centers has continued to improve, and the average power utilization rate (PUE) of ultra-large data centers is 1.46. Excellent green data centers have led the world, with PUE reaching 1.2-1.3. However, the total energy consumption of my country's data centers is still growing at a rapid rate, which is significantly higher than the world average. On the one hand, this is because the scale of data center construction in my country is growing rapidly. On the other hand, there is considerable room for improvement in the energy saving of data centers in my country. Under the guidance and requirements of the "double carbon" goal, it is imperative to save energy and reduce emissions in data centers.
In November 2021, the National Development and Reform Commission and other departments issued the "Implementation Plan for Implementing the Carbon Peak and Carbon Neutral Target Requirements and Promoting the Green and High-Quality Development of New Infrastructure such as Data Centers and 5G" (hereinafter referred to as the " Plan"), which puts forward specific goals for promoting the green and high-quality development of new infrastructure such as data centers and 5G.
The "Plan" points out that by 2025, data centers and 5G will basically form a green and intensive integrated operation pattern. The average power utilization efficiency of newly built large and ultra-large data centers across the country has dropped below 1.3, the national hub nodes have further dropped below 1.25, and the green and low-carbon level has reached 4A or above. The utilization rate of data centers in the western region has increased from 30% to more than 50%, and the supply and demand of computing power in the eastern and western regions are more balanced.
As for the significance of implementing the "East and West" project, Sun Wei gave four "benefits". Specifically, first, it is conducive to improving the country’s overall computing power level. Through the nationwide integrated data center layout and construction, the scale of computing power facilities will be expanded, the efficiency of computing power usage will be improved, and the scale and intensification of national computing power will be achieved.
Second, it is conducive to promoting green development. Expanding the layout of data centers in the west will significantly increase the proportion of green energy used in data centers, which will help to consume green energy in the west. At the same time, we will continue to optimize data centers through technological innovation, replacing large ones with small ones, and low-carbon development. Energy efficiency.
Third, it is conducive to expanding effective investment. The data center industry chain is long, the investment scale is large, and the driving effect is strong. Through the construction of computing power hubs and data center clusters, it will effectively drive upstream and downstream investment in the industry.
Fourth, it is conducive to promoting coordinated regional development.
Sun Wei pointed out that the layout of computing power facilities from east to west will drive the effective transfer of related industries, promote data circulation and value transfer between the east and west, extend the development space of the east, and help form a new pattern of western development.
