Cornelis launches 800G networking range for AI and supercomputers
Server makers Dell, Lenovo and Supermicro plan to support the CN6000 hardware, with systems due in early 2027.
Cornelis has unveiled CN6000, an 800G range of network switches and cards aimed at supercomputers and artificial intelligence clusters. The company is challenging Nvidia’s InfiniBand with hardware that it says offers lower latency, citing tests it conducted itself.
The main card uses Omni-Path technology and can process 1.6 billion messages per second, according to Cornelis. The company reports a 21% speed advantage over InfiniBand for transferring a small message. That comparison does not establish a 21% reduction in job completion times, which vary by workload.
Another card in the range targets standard Ethernet, used by most AI data centers. Support for Ultra Ethernet, a newer standard, is due later. The cards support chips made by Qualcomm, Nvidia, Intel and AMD.
Server manufacturers planning support include Supermicro, Dell and Lenovo; their systems are due in early 2027. Intel dropped Omni-Path in 2019 and spun the business off as Cornelis in 2020.
