Nvidia contributes its Vera Rubin NVL72 rack and compute tray designs to the Open Compute Project at OCP Summit 2026
Open standards are the foundation for AI factories that can scale from megawatts to gigawatts. At #OCPSummit26, we contributed the NVIDIA Vera Rubin NVL72 rack and compute tray designs to @OpenComputePrj through the open 3rd generation NVIDIA MGX architecture. We also announced advances across open source software, AI networking, pluggable optics, facility design standards and more, giving the industry a common foundation for next-generation AI factories.

Context
Opening up the rack design for its flagship AI system lets other hardware makers build compatible gear, which could speed up and standardize gigawatt scale AI data center buildouts.
The Open Compute Project is an industry group, started by Facebook, that publishes open hardware designs for data centers. MGX is Nvidia's modular reference architecture for building servers and racks around its chips. Vera Rubin NVL72 is Nvidia's next rack scale system, pairing its Vera CPUs with Rubin GPUs.
Deep dive
On October 12, NVIDIA AI Infrastructure posted that at OCP Summit 2026 Nvidia contributed the Vera Rubin NVL72 rack and compute tray designs to the Open Compute Project through the open third generation MGX architecture, and announced advances across open source software, AI networking, pluggable optics and facility design standards.
According to Nvidia's blog, the event took place at the San Jose McEnery Convention Center. Nvidia said the updated MGX 1.2 specification adds rack scale blind mate liquid cooling, interoperable rack scale interconnects and a liquid cooled 5,000A busbar for higher power systems, and supports rack deployments up to 250kW. It also contributed a design for a Vera CPU rack meant for tool calling, orchestration and sandboxed execution by AI agents.
The blog listed partner announcements as well: open AI factory design and grid resilience standards published with hyperscalers, new open source components for its DSX AI factory software, networking work with Meta on Spectrum X Ethernet, an 800V DC factory design from Visionbay, a new pluggable optics standard with Cisco called USFP, and Falcon Transport support with Google on future ConnectX 10 SuperNICs and BlueField DPUs.
Ian Buck, Nvidia's vice president of hyperscale and high performance computing, spoke about open infrastructure at the event, Nvidia said.
What to expect next
Watch which server makers and cloud providers ship Vera Rubin systems built on the contributed MGX designs, and whether the open specs reduce the time it takes to bring new AI data centers online.
Also watch how rival chipmakers such as AMD respond at OCP, since open rack standards built around Nvidia's architecture could make it harder for alternative accelerators to fit into the same data center designs.
