Supermicro begins shipping NVIDIA Vera Rubin NVL72 GPU server racks, marking production availability of NVIDIA's latest high-density GPU platform for AI data centers.

Super Micro Computer, Inc. (NASDAQ: SMCI) is now shipping NVIDIA Vera Rubin NVL72 racks integrated with Supermicro's Data Center Building Block Solutions® (DCBBS) and its direct liquid cooling stack (DLC-2). The full liquid-cooling stack is optimized for the NVIDIA Vera Rubin platform, from cold plates to cooling distribution units (CDUs) to cooling towers.

Supermicro's DCBBS Blueprints define a balanced bill-of-materials spanning from 5 MW to gigawatt scale, delivering up to 1,152 GPUs and 331 TB of HBM4 per Scalable Unit. The company provides one accountable team across site survey, project design, integration, L11 and L12 testing, on-site deployment, and ongoing support.

"We have spent years building the liquid-cooling stack, the manufacturing capacity, and the deployment teams for exactly this moment," said Charles Liang, president and CEO, Supermicro. "Our customers can now order a Scalable Unit and receive production-ready systems with end-to-end integration, because we design and build every layer between the cold plate and the cooling tower. Our development of DLC-2 technology is what sets Supermicro apart and allows us to deliver the most complete solution for the NVIDIA Vera Rubin platform."

The NVIDIA Vera Rubin platform was designed in conjunction with direct liquid cooling technology to deliver AI-throughput-per-watt at efficiency levels unachievable with air cooling alone. With greater AI operations per second comes a greater heat load—heat must be moved through the full fluid distribution loop, from the cold plates through manifolds to the cooling tower. Supermicro tests and validates every rack with the full liquid cooling stack, reducing time-to-online.

Supermicro's path to production spans from the mechanical engineering of individual system nodes and large-scale manufacturing of liquid-cooled racks to full onsite deployment of clusters based on NVIDIA reference architecture. The company's DCBBS provides comprehensive thermal expertise and an in-house portfolio of liquid cooling components, including cold plates, manifolds, hose kits, rack power shelves, in-row and in-rack cooling distribution units, Liquid-to-Air sidecar CDUs, rear door heat exchangers, and facility-side cooling towers—all from a single portfolio.
