Nvidia has contributed its GB200 NVL72 rack and compute/switch tray designs to the Open Compute Project (OCP), enabling OCP members to build their designs based on Nvidia Blackwell GPUs. The company is sharing key design elements of its high-performance server platform to accelerate the development of open data center platforms that can support Nvidia's power-hungry next-generation GPUs with Nvidia networking.
The GB200 NVL72 system with up to 72 GB100 or GB200 GPUs is at the heart of this contribution. Nvidia shares critical electro-mechanical designs, including details about the rack architecture, cooling system, and compute tray components. The GB200 NVL72 system features a modular design based on Nvidia's MGX architecture that connects 36 Grace CPUs and 72 Blackwell GPUs in a rack-scale configuration. This setup provides a 72-GPU NVLink domain, allowing the system to act as a massive single GPU.
