NVIDIA opens Vera Rubin rack designs at OCP as hyperscalers publish shared AI data center specs

At the Open Compute Project Global Summit in San Jose, NVIDIA said on 12 October 2026 that it has contributed key Vera Rubin rack and compute tray designs to the Open Compute Project through its open MGX architecture. NVIDIA says the updated MGX 1.2 specification adds blind-mate liquid cooling and a liquid-cooled 5,000A busbar. It also published a Vera CPU rack design aimed at agent workloads such as tool calling, orchestration and sandboxed execution. Alongside it, NVIDIA, AMD, Google and Meta published the Open Data Center Specification v0.7, a shared blueprint for AI data center power, cooling and layout. Google, Meta, Microsoft and NVIDIA published an OCP Grid Resilience Specification, which sets out how large AI sites should stay connected during grid disturbances and restore to near-full load within less than two seconds. NVIDIA also released open-source software for running clusters, and Cisco announced plans with NVIDIA for USFP, a new optical module form factor that the companies say will deliver four times the bandwidth density of 200Gb/s-per-lane pluggable optics. The performance claims are the companies' own.
