Supermicro and Cornelis have announced that Supermicro’s liquid-cooled FlexTwin server platforms are now fully validated with Cornelis’ CN5000 400 Gbps networking solution. This integration is targeted at data centers running artificial intelligence (AI) and high-performance computing (HPC) simulation workloads that require large clusters and efficient infrastructure. Both companies say the joint solution enables data centers to scale performance while controlling power, cooling, and network congestion limits.
According to the announcement, the Cornelis CN5000 networking platform delivers 400 Gbps data rates, enabling predictable, congestion-free server-to-server communication in large AI and HPC deployments. Supermicro’s FlexTwin platform features a dense, liquid-cooled server design that can capture up to 95 percent of system heat. The CN5000 portfolio supports both air-cooled and liquid-cooled network switches, as well as air-cooled and conduction-cooled options for the CN5000 SuperNIC, which gives operators multiple deployment options for high-performance networking in varied thermal environments.
Joint testing conducted by Supermicro and Cornelis across manufacturing, physics, life sciences, and climate workloads reports up to 1.5 times higher application performance versus competing 400 Gbps network fabrics. The partnership also claims an average 29 percent improvement in performance per networking dollar and up to 2.3 times higher performance per watt in liquid-cooled setups, as well as improved scaling efficiency for large clusters.
The companies identify data center applications—including AI model training, advanced simulation, and data-intensive scientific research—as primary targets for the validated solution. These workloads are increasingly limited by power availability, cooling capacity, and network congestion, rather than sheer compute capability.
Lisa Spelman, CEO of Cornelis Networks, stated, “The infrastructure demands of AI and modern simulation have fundamentally changed, with power, cooling, and network scalability emerging as the new gating factors,” “By combining Supermicro’s advanced liquid-cooled FlexTwin architecture with our high-performance CN5000 networking platform, customers gain a proven way to scale performance without paying the traditional penalties in power, cost, or complexity.”
The FlexTwin server platform with CN5000 networking is available now from Supermicro and authorized Cornelis partners.
