# OCP Global Summit: Nvidia contributes Vera Rubin rack designs

Full title: OCP Global Summit: Nvidia contributes Vera Rubin rack designs; hyperscalers publish open data-center and grid-resilience specs

At the Open Compute Project Global Summit in San Jose on Oct 12, 2026, Nvidia contributed its Vera Rubin rack and compute-tray designs to OCP through the open MGX architecture (MGX 1.2 supports racks up to 250 kW). Nvidia, AMD, Google and Meta published an Open Data Center Specification v0.7, and Google, Meta, Microsoft and Nvidia published a Grid Resilience Specification for how AI data centers behave during grid disturbances. Nvidia and Cisco announced a new pluggable optics format, USFP.

## Key facts
- Nvidia contributed 'key NVIDIA Vera Rubin rack and compute tray designs' to OCP via MGX; MGX 1.2 adds rack-scale blind-mate liquid cooling, a liquid-cooled 5,000A busbar and support for racks up to 250 kW
- Open Data Center Specification v0.7 (Nvidia, AMD, Google, Meta): a common blueprint for AI data-center power, cooling and layout
- OCP Grid Resilience Specification (Google, Meta, Microsoft, Nvidia): large AI sites should stay connected during grid disturbances, respond automatically and restore to near-full load in under two seconds
- Meta adopts Nvidia Spectrum-6 102.4 Tb/s Ethernet switches (its N-IceCube switch, running FBOSS); 'multiplane' networking is aimed at clusters of more than 100,000 GPUs
- Nvidia and Cisco: Ultra-Dense Small Form Factor Pluggable (USFP), described as the first module for 400 Gb/s-based networking fabrics
- Nvidia and Google: Falcon Transport support on future ConnectX-10 SuperNICs and BlueField DPUs
- New open-source DSX OS components from Nvidia: Config Manager, Cluster Readiness Engine, Rack Management Service, Cluster API provider

## What happened

Nvidia used the OCP summit to open parts of its next rack platform and to publish facility standards together with its largest
customers. Ian Buck, Nvidia's vice president of hyperscale and high-performance computing, presented the announcements. Visionbay
also showed plans for "K-1", a data-center design built around Nvidia's 800-volt DC power architecture.

## Why it matters

Gigawatt-scale sites need suppliers of racks, power gear and cooling to build to one target. Open rack and facility specifications let
manufacturers start before each customer issues its own design. The grid specification answers a concern of utilities: very large AI
loads that disconnect suddenly during a fault can destabilise the grid. The same day Microsoft detailed its own 167 kW Maia 300 rack,
which shows the power density these standards are written for.
