Inspur Information Releases New Server Optimized for Mobile Liquid Cooling Cluster

28 July 2020

The 2U 4-node high-density server i24M5-LC adopts industry-leading cold plate liquid cooling technology and conducts heat exchange by means of warm water cooling, achieving a PUE of <1.2

San Jose, California, July 22 – Inspur Information, a leading provider of data center infrastructure products and solutions, recently released a next-generation plate liquid-cooling 2U 4-node high-density server i24M5-LC, optimized for large-scale water-cooling server data centers with PUE<1.2. Meanwhile, Inspur Information also released a mobile rack-mounted Coolant Distribution Unit (CDU), which can be connected to the i24M5-LC with quick release connectors for easy deployment of a complete liquid cooling system, providing customers with an efficient and convenient mobile liquid cooling cluster solution.

The i24M5-LC adopts a liquid cooling optimized design based on the i24M5 server. Inspur's high-density i24M5 server is a 2U four-node rack-mounted system optimized specifically for high-density data center applications. Four 1U half-width two-socket nodes can be mounted in the chassis, demonstrating its high density, efficiency, and reliability in a limited space. Its extreme scalability makes it ideal for high-performance computing and cloud platform construction. The previous air-cooled design is optimized with the cold plate liquid cooling technology, resulting in greatly enhanced heat dissipation efficiency at a minimal cost. Furthermore, this cold plate liquid cooling method has superior cooling potential and can fulfill the even higher heat dissipation demands of next-generation processors.

i24M5-LC adopts industry-leading cold plate liquid cooling technology and conducts heat exchange by means of warm water cooling, achieving a PUE of <1.2 upon testing. Each node of the i24M5-LC is equipped with a leak detection module with alarms to quickly and accurately detect leaks at server nodes. Meanwhile, the cabinet is included in the monitoring system for overall design. With node-level and cabinet-level leakage detection, intelligent monitoring in the true sense of the word can be achieved. The i24M5-LC also delivers good compute performance, with a single node supporting 2 Intel Xeon scalable processors for a maximum power of 205W. A perfect combination of performance and power consumption makes it an exemplary 2U 4-node high-density server. The i24M5-LC can be widely used in computing-intensive supercomputing centers as well as cloud data centers in industries such as Internet, finance and telecommunications.

Meanwhile, Inspur also released RackCDU-F004, a rack-mounted liquid cooling CDU which can be connected to the i24M5-LC with quick release connectors for easy building of a complete liquid cooling system. In a space of less than 0.5 square meters and a height of 8U, it supports 8 two-socket CPU liquid-cooling servers and rack-mounted liquid-cooled CDUs, achieving an innovative, complete miniaturized mobile liquid cooling cluster. It not only meets customer needs for efficient and convenient mobile liquid-cooled clusters and rapid building of small-scale liquid-cooled clusters, but also enables further expansion of nodes through coupled installation of multiple systems. This mobile liquid-cooled cluster system no longer relies on heat exchange on the primary side, greatly simplifying the deployment environment of liquid cooling clusters. In a sense, this quick-installed mobile liquid cooling cluster system fundamentally solves the deployment problem of traditional liquid cooling systems, and provides customers with a cost-effective liquid cooling cluster solution.
