After the "South-to-North Water Transfer", China started "counting the East and counting the west"

2022-02-18

Recently, the national development and Reform Commission and other departments jointly issued a notice, agreeing to start the construction of National Computing hub nodes in 8 places, including Beijing, Tianjin and Hebei, the Yangtze River Delta, Guangdong, Hong Kong and Macao Dawan District, Chengdu and Chongqing, Inner Mongolia, Guizhou, Gansu and Ningxia, and planned 10 national data center clusters, which means that the overall layout design of the national integrated big data center system has been completed, The project of "counting from the east to the west" was officially launched. After the power transmission from the west to the East and the South-to-North Water Transfer, China has once again carried out large-scale cross regional resource allocation in its vast territory. Computing from the east to the West will become an important infrastructure for China's future development, especially the development of digitization. Unbalanced computational space In "East number and West calculation", the "number" refers to the data, and the "calculation" refers to the computing power, that is, the processing capacity of the data. "Counting from the east to the west" is to guide the demand for computing power in the east to the West in an orderly manner by building a new computing power network system integrating data center, cloud computing and big data. The reason for this arrangement lies in the predictable surge of computing power demand and the predictable bottleneck of computing power supply in China's future development. At present, a new round of scientific and technological revolution and industrial reform are reshaping the global economic structure. As the core productivity of digital economy, computing power has become a new focus of global strategic competition. According to the relevant person in charge of the national development and Reform Commission, up to now, the scale of China's data center has reached 5 million standard racks and the computing power has reached 130eflops (1.3 trillion floating-point operations per second). With the comprehensive and continuous penetration of digital technology into all fields of economy and society, the demand for computing power in the whole society is still very urgent, and it is expected to grow rapidly at a rate of more than 20% every year. Computing power has become an important infrastructure for national economic development. Accelerating the construction of computing power will effectively stimulate the innovation vitality of data elements, accelerate the process of digital industrialization and industrial digitization, give birth to new technologies, new industries, new formats and new models, and support high-quality economic development. However, China's computing power supply is facing challenges. From the perspective of spatial distribution, at present, most of China's data centers are distributed in the East. Under the tight situation of land and other resources, it is difficult to develop data centers on a large scale in the East. Moreover, the operation of the data center needs power support. Energy consumption alone makes it difficult for the eastern region to afford. Therefore, in order to meet the rapidly growing demand for computing power in the whole country, especially in the eastern region, there must be support from the west, but how to support it is very learned. Watt and bit multiple choice questions As for how to give play to the supporting role of the west, policymakers are faced with a multiple-choice question. In terms of image, is it to send watts or bits? Sending watts is to choose to place a large number of data centers in the East, give full play to the energy advantages of the west, send power to the East, and support the data center in the east to form a computing power supply. Bit sending is to choose to build a large-scale data center in the west, obtain computing power through local use of energy, and send the data to the east to support the demand for computing power in the East. The advantages and disadvantages of the two schemes are relatively clear. Power transmission and large-scale construction of data center in the East can reduce the impact of network delay, but on the one hand, it can not solve the problem of land shortage. On the other hand, long-distance transmission will have about 10% energy loss. Sending bits and building a large-scale data center in the West will greatly reduce energy consumption, and there is no such problem in transmitting digital signals with optical fiber. What needs to be paid attention to is the factor of network delay. Therefore, the scheme of sending bits finally surfaced. The official decided to build a large-scale data center in the west to form computing power to support the needs of the East and realize the calculation from the east to the West. Keywords: intensification, gradient, iteration According to the relevant person in charge of the national development and Reform Commission, there are three ideas for counting from the east to the West. One is to promote the moderate agglomeration and intensive development of national data centers. Through the layout of 8 computing hubs across the country, guide large and super large data centers to gather in the hub to form a data center cluster. Give play to the effect of scale and intensification, increase policy support, improve the scale and efficiency of the overall computing power, and drive the development of upstream and downstream industries related to the data center. Between computing hubs, open up high-speed data transmission networks, strengthen cloud network integration and multi cloud collaboration, promote efficient complementarity and collaborative linkage of computing power between the East and the west, and accelerate the rational layout, optimization of supply and demand, green intensification and interconnection of national data centers. The second is to promote the echelon layout and overall development of the data center from east to west. On the one hand, accelerate the large-scale layout of the data center to the west, especially for businesses with low network requirements such as background processing, offline analysis, storage and backup, which can be transferred to the West first and undertaken by the western data center. On the other hand, due to the delay caused by long-distance network transmission and related supporting facilities, the western data center can not meet all computing power needs. Some businesses with high network requirements, such as industrial Internet, financial securities, disaster early warning, telemedicine, video call and artificial intelligence reasoning, can be arranged in Eastern hubs such as Beijing Tianjin Hebei, Yangtze River Delta, Guangdong, Hong Kong and Macao Bay area. Within the hub, we should focus on promoting the transfer of data centers from first tier cities to the surrounding areas to ensure that computing power deployment is related to land, energy, water The coordination and sustainability of electricity and other resources. The third is to realize the gradual and rapid iteration of "counting from the east to the west". In order to resolutely avoid the blind development of data centers, at the current initial stage, 10 data center clusters are planned and established in 8 computing hubs, the physical boundary is delimited, and the development goals of green energy conservation and shelf availability are defined. For example, the average shelf rate of data centers in the cluster should reach at least 65%, and the utilization rate of renewable energy should be significantly improved. Through multi index constraints, promote high standards and strict requirements of clusters and minimize the start. The cluster development will be dynamically monitored to scientifically evaluate the development level and saturation degree of cluster computing power. In combination with the development situation, we will continue to optimize and improve the layout in the future, timely expand the cluster boundary or increase clusters, demonstrate the new computing power hub, and realize the overall, orderly and healthy development of computing power. Policy choice of killing three birds with one stone The promotion of counting from the east to the West will bring the effect of killing three birds with one stone. The first is the upgrading of the computing power supply system. Through the large-scale and intensive effects of the eight computing power hubs, it can improve the overall computing power scale and efficiency of the region where the computing power hub is located, and drive the development of upstream and downstream industries related to the data center. Between computing hubs, optimize the network structure, open up the high-speed data transmission network, strengthen cloud network integration and multi cloud collaboration, promote efficient complementarity and collaborative linkage of computing power between the East and the west, and accelerate the rational layout, supply and demand balance, green intensification and interconnection of data centers across the country. The second is to drive the economic development of the East and West. The East, where the demand for computing power is growing rapidly, can undoubtedly benefit from counting from the East and counting from the West. For the west, the construction of data center also provides a strong driving force for growth. This power comes from the extremely long industrial chain involved in the construction and operation of the data center, including not only traditional civil engineering, but also many industries such as it equipment manufacturing, information communication, basic software and green energy supply. The industrial chain is long, covers a wide range of categories and has a great driving effect. By coordinating and optimizing the layout and promoting the accurate development of the data center, it will effectively drive the upstream and downstream investment of the industry. The third is to support the data transformation of small and medium-sized enterprises. For small and medium-sized enterprises, computing power will be the infrastructure for data transformation in the future. The computing power network constructed by East digital West computing can promote the construction of data centers according to local conditions and realize differentiated and complementary development, so as to avoid repeated investment and construction. Through the use of emerging technologies and modes such as cloud network collaboration and multi cloud collaboration, we can further improve the intensive level of data center, improve resource utilization efficiency, provide richer cloud services for small and medium-sized enterprises, help small and medium-sized enterprises reduce the cost of cloud usage and accelerate the realization of digital transformation.
