At the OCP Global Summit, NVIDIA announced Vera Rubin rack and compute-tray design contributions through MGX on October 12. The event concerns industrial interfaces connecting compute, networking, power and cooling, not publication of complete GPU designs that anyone can reproduce freely.
MGX 1.2 adds rack-scale blind-mate liquid cooling, a liquid-cooled 5,000 A busbar and more standardised interfaces. NVIDIA describes rack deployments up to 250 kW. These are infrastructure design and capacity characteristics, not guaranteed consumption for every system or energy savings measured at every customer.
DSX software expands with public components for network configuration, cluster readiness testing, rack management and bare-metal provisioning. The same announcement covers facility and grid-resilience standards, networking developments with Meta, planned USFP optics with Cisco and Falcon Transport on future hardware. Published components must remain distinct from future compatibility and deployments.
For European operators, common interfaces can simplify sourcing and maintenance without removing cooling or power constraints. Technical teams should inspect each component’s specifications and license, then validate actual equipment: a standards contribution certifies neither universal interoperability nor automatic cost savings.
