ASRock 4U16X-GNR2 Packs 8 B300 GPUs, Demands Liquid Cooling
Summary
ASRock Rack's 4U16X-GNR2 packs eight NVIDIA HGX B300 GPUs into a 4U chassis with liquid cooling, delivering extreme density for AI training, inference, and HPC clusters. The design emphasizes integrated cooling, high-speed front-mounted networking, and local NVMe storage, requiring careful facility readiness and fabric planning. It showcases a shift toward node-centric AI infrastructure where density, cooling, and IO topology are as critical as the GPUs themselves.
