CTOnews.com news on December 17, at the 2022 Wuhan High performance Computing Conference, Changjiang Computing unveiled the full liquid-cooled complete cabinet of Kunpeng data Center-Changjiang Computing Acceler 5000 PoD, which will be oriented to scientific computing, cloud rendering, big data and other recalculating scenarios to help build a very large-scale data center cluster. The product provides up to 2.5PFlops computing power and brings better energy efficiency performance and ease of deployment and management.

The Changjiang Computing Acceler 5000 PoD adopts a standard cabinet design with a height of 47U and a power density of 66kW; when fully equipped, 32 1U dual liquid-cooled server nodes can be installed, providing 64 Kunpeng 920 CPU and 128kW GPU, with a total double-precision floating-point computing power of 2.5PFlops, equivalent to 8 traditional cabinets; at the same time, cabinet top switches, power supplies and liquid-cooled cooling pipes and accessories are also integrated in the cabinet. Users can not only customize the cabinet configuration according to the power supply, load-bearing and other related needs, but also quickly expand the overall computing power through the joint deployment of multiple cabinets.

By using mature and efficient cold plate liquid cooling, the Yangtze River calculates that Acceler 5000 PoD allows cryogenic liquids to quickly remove heat from energy-intensive components such as CPU, memory, GPU, and so on. As a result, CPU, GPU and other components can get a better heat dissipation environment, so that they can run at higher frequencies and achieve higher, more lasting and more stable computing performance.

While achieving higher heat dissipation performance, the Yangtze River calculation Acceler 5000 PoD has higher centralized heat transfer efficiency. By using the longitudinal eddy current generator and the field coordination optimal coordination angle in the liquid-cooled heat exchanger, the matching heat exchanger can also achieve a 20% increase in heat transfer efficiency.

This allows liquid-cooled data centers to achieve PUE performance of no more than 1.15, which means that data centers can save about 20% of their electricity costs each year. The extremely low PUE value can help data centers meet the increasingly stringent energy conservation and emission reduction policies.

At the deployment level, Changjiang Computing Acceler 5000 PoD can significantly reduce deployment time through the prefabrication, packaging, transportation and delivery of complete cabinets, and users only need to install coolant lines and liquid-cooled heat exchangers according to the actual situation in the data center. At the same time, users can also choose cabinet doors with different designs and functions according to their needs. In practice, it takes only 2-3 days to complete the on-site deployment, which is 90% shorter than the traditional deployment model.

At the internal design level, Changjiang Computing Acceler 5000 PoD practices the concept of "zero cable". CTOnews.com learned that through a series of designs, such as the easy-to-plug interface of the power supply, the full backplane connection of the network, and the specially designed coolant pipeline sealing interface, all nodes in the cabinet were quickly "completely blind", which not only greatly reduced the workload and difficulty of operation and maintenance, but also reduced the probability of damage, virtual connection and pipeline leakage during long-term operation and maintenance in the future.

At the operation and maintenance management level, the servers and switches in the cabinet can connect with the FusionDirector intelligent management system by using RESTful API's Redfish interface to provide a unified and intelligent management portal for infrastructure management, realizing a series of intelligent functions such as version management, deployment management, asset management, energy efficiency management, fault management and so on.
