On October 12, NVIDIA announced at the OCP Global Summit that it is contributing Vera Rubin rack and compute tray designs to OCP via the open MGX architecture, enabling system makers to build next-generation AI factory infrastructure. The updated MGX 1.2 specification adds rack-level blind-mate liquid cooling, interoperable rack interconnects, liquid-cooled 5000A busbars, and native 19-inch device support, with deployments up to 250kW per rack.
