Recently, the national development and Reform Commission, the central network information office, the Ministry of industry and information technology and the National Energy Administration 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, Macao, Dawan District, Chengdu and Chongqing, Inner Mongolia, Guizhou, Gansu and Ningxia, and planned 10 national data center clusters. So far, the overall layout design of the national integrated big data center system has been completed, and the "counting from the east to the west" project has been officially launched. The so-called "computing from the east to the west" refers to the construction of a new computing power network system integrating data center, cloud computing and big data, orderly guiding the computing power needs of the east to the west, optimizing the construction layout of the data center and promoting the collaborative linkage between the East and the West. In short, it is to make the computing resources in the West more fully support the computing of data in the East and better empower the digital development. The high technology department of the national development and Reform Commission pointed out that most of China's data centers are distributed in the eastern region. Due to the increasing shortage of land, energy and other resources, it is difficult to sustain the large-scale development of data centers in the eastern region. The western region of China is rich in resources, especially renewable energy, and has the potential to develop data centers and undertake the computing power needs of the East. Therefore, we should give full play to the advantages of China's system and mechanism, integrate the layout from a national perspective, optimize the allocation of resources and improve the efficiency of resource use. Source: National Development and Reform Commission (the same below) Huawei, Alibaba, Tencent and other technology giants responded one after another As another important strategic project after the "South-to-North Water Transfer", "west to East power transmission" and "west to East Gas Transmission", the "east to West calculation" emphasizes the overall optimization thinking, and changes from the past single and discrete to the current overall and collaborative direction. After attracting a lot of attention from the market, a number of domestic science and technology enterprises have also disclosed their layout in new infrastructure fields such as "counting from the east to the west". Huawei disclosed to observer.com that in order to respond to the national "east to West computing" project and help achieve the strategic goal of "carbon peak and carbon neutralization", the company's cloud Gui'an data center phase I has been put into use. Gui'an data center is planned to be Huawei's largest cloud data center in the world, which can accommodate 1 million servers and is an important bearing node of Huawei's cloud business, It carries Huawei cloud, Huawei process it, consumer cloud and other services. At present, huaweiyun has five data centers in China. Among them, Gui'an and Ulanqab are the two cloud data centers of Huawei cloud one south and one north. The company also has three core data centers in Beijing, Tianjin and Hebei, the Yangtze River Delta, Guangdong, Hong Kong and Macao. The cold, warm and hot layout of Huawei cloud data center is determined by the time delay. The cold service is built in low-cost areas, the warm service can be close to low-cost areas along the coast, and the hot service should be arranged in areas close to customer needs. Alibaba cloud disclosed that the company's hub nodes such as Beijing Tianjin Hebei and Inner Mongolia have data centers. In the Beijing Tianjin Hebei hub, Zhangbei data center was put into operation in September 2016, vigorously using green energy such as wind power and photovoltaic, and deploying the largest submerged liquid cooling cluster of domestic cloud computing data center. At the same time, the Xuanhua data center under construction also belongs to the Beijing Tianjin Hebei hub in the "counting from the east to the west" project. In the hub of Inner Mongolia, the super data center built by Alibaba cloud in Ulanqab officially began to provide cloud computing services in June 2020; In Chengdu Chongqing hub, Alibaba cloud Western cloud computing center and data service base were settled in Chengdu in November 2020. It is an important support for Alibaba cloud Western business. It will comprehensively adopt various technologies, such as server customization, artificial intelligence chip, heterogeneous computing, large-scale network cluster, etc., to improve the technical level and computing output of the overall project. As the "national team" in the communication field, China Mobile told observer.com that in terms of computing infrastructure, the company first connected with the national deployment of "computing from the east to the west", deepened the top-level design, and improved the planning and construction schemes such as computing service resource pool and network interconnection of the whole network; Second, strengthen the interconnection and unified scheduling of computing resources throughout the network, and speed up the construction and deployment of edge cloud; Third, continue to promote the integration of three clouds, give priority to the sharing of mobile cloud and it cloud infrastructure and common capabilities, and study and formulate the architecture scheme and deployment strategy of IAAs layer integration. In terms of backbone transmission network transformation, relying on the "4 + 3 + X" data center layout, network nodes will be deployed as needed, direct links will be added, and the networking architecture will be adjusted to realize full interconnection networking between mobile cloud center nodes. Byte beat's volcanic engine responded that it is strengthening the talent training and recruitment of the western data center, as well as the upstream and downstream industrial chain construction of the western data center, including the industrial chain and supply chain construction of data center infrastructure, data center related consumables, servers / switches and other spare parts. In the future, more consideration will be given to the location of data centers. In areas rich in clean energy such as wind and solar energy, the utilization rate of renewable energy can reach 100%, and new technologies and products such as green energy and low energy consumption will be explored. Tencent also takes the data center as the construction focus. The company told observer.com that Tencent has put into operation Gui'an Seven Star disaster recovery data center in Guizhou hub, covering a total area of about 470000 square meters. According to the plan, 300000 servers will be stored, and phase I trial operation has been started in May 2018; In the Beijing Tianjin Hebei hub, Tencent has deployed two data centers in Huailai ruibei and Dongyuan, which are planned to accommodate more than 300000 servers and have been partially put into operation; In the Yangtze River Delta hub, Tencent has Qingpu data center; In the Chengdu Chongqing hub, Tencent cloud deployed two cloud computing data centers in Chongqing, of which phase I was put into operation in June 2018, which can accommodate 100000 servers. It is Tencent's fourth self built large-scale data center cluster after Tianjin, Shanghai and Shenzhen Shantou cooperation zone. Cloud computing service provider Youke also has a layout in the Yangtze River Delta, Inner Mongolia and other hub nodes of "counting from the east to the west". Its Shanghai Qingpu cloud computing center and Wulanchabu cloud computing center are respectively located in the Yangtze River Delta and Inner Mongolia nodes of the national hub node of the national integrated computing network. The two data centers belong to the National Computing hub node. The first phase of Ulanchab cloud computing center has been put into operation in September 2021, and Qingpu cloud computing center will also be completed and put into operation in 2022. Four important meanings of "counting from the east to the west" 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. Up to now, the scale of China's data center has reached 5 million standard racks, and the computing power has reached 130 eflops (1.3 trillion floating-point operations per second).
