Research note
Research note: Nvidia opens its Vera Rubin rack designs to the Open Compute Project at OCP Global Summit
How we checked what Nvidia contributed to the Open Compute Project and which figures are Nvidia’s own.
What we set out to check
What Nvidia contributed, what the new specifications cover, which companies are involved, and which numbers are Nvidia’s claims.
What we found
- Nvidia’s post confirms the MGX 1.2 contribution, the 250kW rack figure and the partner specifications.
- An independent summary matches the main facts.
Numbers that differ
None between the sources.
Labels we chose and why
- Confirmed for what Nvidia says it contributed and announced.
- Company claim for performance figures such as 400Gb/s per lane, which are Nvidia’s and Cisco’s targets.
What we could not verify
- The specification documents themselves on the OCP site.
- When partner hardware based on the designs will ship.
This is a lighter-sourced story than we prefer: only one independent outlet had covered it when we checked. We will add sources as coverage grows.
What we searched
- Nvidia OCP 2026 Vera Rubin MGX 1.2
- Open Data Center Specification v0.7
- Nvidia Cisco USFP optics Spectrum-6 Meta
