Blueprints for racks of the most powerful SI servers are now shared, so more than Nvidia itself can build SI factories.
At the OCP summit, Nvidia opened the Vera Rubin rack and compute tray designs through its MGX architecture so system builders can make SI servers to common standards. It also published the MGX 1.2 specification with rack-level blind-mate liquid cooling (up to 250 kW), a rack design with Vera processors for agentic workloads, and four open-source components of the DSX OS software. Nvidia says Cisco, Google, Meta, Microsoft, Visionbay and AMD worked on the initiatives; Spectrum-6 switches deliver 102.4 Tb/s, and multiplane technology allows SI factories of more than 100,000 GPUs.
