Super Micro Computer, Inc. (SMCI) announced the expansion of its NVIDIA Blackwell architecture portfolio with the introduction and shipment availability of new 4U and 2-OU (OCP) liquid-cooled NVIDIA HGX B300 systems. These latest additions are a key part of Supermicro's Data Center Building Block Solutions (DCBBS) that deliver unprecedented GPU density and power efficiency for hyperscale data centers and AI factory deployments. The 2-OU liquid-cooled NVIDIA HG X B300 system, built to the 21-inch OCP Open Rack V3 (ORV3) specification, enables up to 144 GPUs per rack to deliver maximum GPU density for hyperscale and cloud providers requiring space-efficient racks without compromising serviceability. The rack-scale design features blind-mate manifold connections, modular GPU/CPU tray architecture, and component liquid cooling solutions.
The system propels AI workloads with eight NVIDIA Blackwell Ultra GPUs at up to 1,100W TDP each, while dramatically reducing rack footprint and power consumption. A single ORV3 rack supports up to 18 nodes with 144 GPUs total, scaling seamlessly with NVIDIA Quantum-X800 InfiniBand switches and Supermicro's 1.8MW in-row coolant distribution units (CDUs). Combined, eight NVIDIA HGX B300 compute racks, three NVIDIA Quantum-X800 InfINBand networking racks, and two Supermicro in-row CDUs form a SuperCluster scalable unit with 1,152 GPUs.
Complementing the 2-OU (OCP). the 4U Front I/O HGX B300 Liquid-Cooled System offers the same compute performance in a traditional 19-inch EIA rack form factor for large-scale AI factory deployments. The 4U system leverages Supermicro's DLC-2 technology to capture up to 98% of heat generated1 by the system through liquid-cooling, achieving superior power efficiency with lower noise and greater serviceability for dense training and inference clusters.
Supermicro's motherboard, power, and chassis design expertise further enables next generation innovation from cloud to edge for global customers. The products are designed and manufactured in-house (in the US, Taiwan, and the Netherlands), leveraging global operations for scale and efficiency and optimized to improve TCO and reduce environmental impact (Green Computing). The award-winning portfolio of Server Building Block Solutions®?
