China's east-to-west computing resource transfer project in full swing

In a big data and cloud computing industrial park located 20 kilometers south of Hohhot city, north China's Inner Mongolia autonomous region, 10,000 Internet Data Center (IDC) racks are operational 24 hours a day.

The industrial park has attracted more than 100 tenants, including government bodies, world-renowned cloud computing service providers, large Internet companies, and banks and insurance institutions.

"The annual average temperature in Hohhot city is eight degrees Celsius, so data centers in the city can use natural cooling sources for about five months of the year," an executive of Chinese telecom operator China Unicom's cloud data center in Hohhot explained.

The innovative combination of the cooling tower and the plate heat exchanger allows the data center to save five million kWh of electricity annually, said the executive, explaining to People's Daily why the company located the data center on grassland in the city.

In February this year, Chinese authorities approved projects to build eight national computing hubs in the Beijing-Tianjin-Hebei region, the Yangtze River Delta region, the Guangdong-Hong Kong-Macao Greater Bay Area, the Chengdu-Chongqing economic zone, Inner Mongolia autonomous region, southwest China's Guizhou province, and northwest China's Gansu province and Ningxia Hui autonomous region, as well as plans on 10 national-data center clusters.

The approval for these projects indicated the completion of the overall layout for China's national integrated big-data center system.

Following the country's other strategic projects that transport natural gas and electricity from western to eastern regions and divert water from the south to the north, the east-to-west computing resource transfer project is in full swing to transfer computing resources from the more prosperous eastern regions of China to the less developed yet resource-rich western regions of the country.

Data centers are major consumers of electricity. By channeling the demand for computing power in the east to the western regions, the east-to-west computing resource transfer project can give full play to these regions' advantages of favorable climate, rich energy sources, good natural environment, etc., and expand the local supply and consumption of renewable energy sources, thus facilitating the low-carbon, green and sustainable development of Chinese data centers.

The mega project also plays a key role in addressing uneven and inadequate development in the country.

According to Wang Tiejun, deputy general manager of the Materials Business Unit of Yangtze Optical Fibre and Cable Joint Stock Limited Company (YOFC), the project will effectively propel the upgrading of the transmission speed of backbone network from 100 Gbps to higher rates such as 200 Gbps and 400 Gbps, thereby generating new market opportunities for YOFC.

Last year, YOFC's new products helped China Mobile realize 1,100 kilometer single-carrier transmission of 800G systems, said Wang, who disclosed that the company has continuously won the largest share of the centralized procurement of new-generation optical fibre and cable by China Telecom and China Mobile, both telecom giants in China.

Many servers manufacturers also believe that the computing resource transfer project has great potential for boosting market growth.

Homemade servers currently enjoy a market share of 74 percent in China, and the figure is expected to be further elevated by the project, said Huang Yue, an executive of Lenovo Infrastructure Solutions Group.

It's estimated that China's server market will see a more than 10-percent growth in revenue in 2022.

As of 2021, 5.2 million server racks were in use in data centers across the country, while the IDC market revenue reached 150 billion yuan (about $22.46 billion) and the size of the country's cloud computing market hit 303 billion yuan, said Yu Xiaohui, head of the China Academy of Information and Communications Technology (CAICT).

It's expected that the number of server racks at data centers in the country would expand by about 20 percent on a yearly basis while the revenue of these data centers would be maintained at between 25 percent and 30 percent during the country's 14th Five-Year Plan (2021-2025) period, when China's cloud computing industry would probably see its average annual growth rate of revenue exceed 30 percent, according to Yu.

The project that channels computing resources from the eastern regions to the western regions of China can drive an increase of about 400 billion yuan a year in investment, said Xu Bin, deputy director of the innovation-driven development center of China's National Development and Reform Commission.

Meanwhile, the computing power-related facilities that have been built and will be built in western China will bring opportunities to industries like information technology and green energy sources in the country's western regions, according to Xu.

Like water conservancy system in the Agricultural Age and electricity in the Industrial Age, computing power represents a crucial component of the foundation for the development of a country's national economy in the era of digital economy.

It's believed that the implementation of China's computing resource transfer project is bound to provide strong support for the Digital China initiative and inject new impetus into the high-quality development of the Chinese economy.
