Alibaba’s open source immersion liquid-cooled data center specification, ODCC promotes the construction of a liquid-cooled ecosystem

On January 6, Alibaba announced that it would officially open the “Submerged Liquid-Cooled Data Center Technical Specifications” to the whole society. As the founding and core member of the Open Data Center Committee (ODCC), Alibaba hopes to work with industry partners to form consensus and open standards for large-scale cloud data center infrastructure, and jointly build China’s cloud data center ecosystem for building Work together for a new generation of green and sustainable data centers.

The submerged liquid-cooled data center standard will be developed around the design, construction, deployment, operation and maintenance of the submerged liquid-cooled data center, including the technical specifications and parameters of the submerged liquid-cooled subsystem, servers, network equipment, and supporting infrastructure. Standards provide a basis for the construction of a new type of data center that is green, energy-saving and efficient in heat dissipation, and improve the level of green data center construction.

In terms of reducing energy consumption in data centers, Alibaba has been at the forefront of the world. From air-cooled, water-cooled to liquid-cooled, Alibaba’s data center has experienced a process from customization to large-scale independent construction in the 20 years of development.

In June 2018, Alibaba deployed the world’s first large-scale liquid-cooled cluster. The server was immersed in a special insulating coolant. The heat generated by the operation can be directly absorbed into the external circulation cooling. The energy consumption for heat dissipation in the whole process is almost Is zero. This form of heat transfer efficiency is a hundred times higher than traditional air cooling, and the energy saving effect exceeds 70%. In the future, Alibaba will gradually promote applications in more data centers.

Compared with the traditional data center deployment method, the immersion liquid-cooled data center is a huge innovation and revolutionary change. The change of IT equipment and other hardware requires a lot of manpower and material investment. The current field is almost completely blank and there is no mature Technology, no standard can be used for reference, there is no standard for components, and the system cost is high.

“What China’s data center lacks is not innovation, but craftsman-level innovation,” said Gao Gaoyuan, chief architect of Alibaba’s infrastructure and general manager of IDC business unit. For more than ten years, Alibaba technicians have regarded the data center as a work of art Polished, Alibaba has the conditions, resources, and responsibility to spend it and share technological dividends with the society.
