NVIDIA unveils Vera Rubin and Kyber for gigawatt AI factories

NVIDIA unveiled MGX and Kyber designs at the OCP Global Summit, presenting open-standard rack and compute-tray architectures and an ecosystem for 800 VDC gigawatt-scale AI data centers.

• Main announcement/action: NVIDIA announced the Vera Rubin NVL144 MGX open-architecture rack servers and previewed the NVIDIA Kyber rack generation; supporting details include: 50+ MGX partners, Kyber to connect 576 Rubin Ultra GPUs by 2027, and Vera Rubin NVL144 features 100% liquid cooling, a midplane PCB replacing cable connections, 45°C liquid cooling, and a liquid-cooled busbar with 20x more energy storage.
• Background/other details: multiple ecosystem partners and implementations were described, including Foxconn’s 40-megawatt Kaohsiung-1 data center (Taiwan) built for 800 VDC, Vertiv’s 800 VDC MGX reference architecture, HPE and others adding product support for NVIDIA Kyber and Spectrum-XGS; the summit (OCP Global Summit) took place Oct. 13-16 at San Jose Convention Center, agenda topics included:
  • Oct. 13-16, San Jose Convention Center — sessions and demos covering MGX rack servers, 800 VDC power delivery, liquid cooling, and Kyber rack architecture
  • Ecosystem showcases from silicon, power system and cooling vendors, and cloud/service providers demonstrating implementations and reference architectures
