NVIDIA HGX™ B300 NVL8 Liquid-Cooled AI Server (4U16X-GNR2/DLC B300)
4U ASRock Rack AI TRAINING / LLM / INFERENCE / HPC / LIQUID COOLING / AI FACTORY
The 4U16X-GNR2/DLC B300 is an ASRock Rack 4U direct-liquid-cooled AI server with the NVIDIA HGX B300 NVL8 GPU module on a dual-socket Intel Xeon 6 (Granite Rapids) platform. It shares the same liquid-cooling mechanism as the AMD version, differing only in CPU platform - Intel offers stronger single-core performance and existing software compatibility, making it a smooth expansion path for data centres already standardised on the Intel ecosystem. Eight-GPU Blackwell Ultra deployment in 4U with NVLink and NVSwitch full-speed interconnect suits large language model training, generative AI inference and AI Factory build-outs. JEI WEI ELECTRONIC is an authorised distributor providing configuration advice, complete system integration, on-site installation and ongoing support - contact us for the full datasheet and a quotation.
