QuantaGrid D75H-10U

The QuantaGrid D75H-10U (prebuilt L6 configuration) is a 10U rackmount server designed for hyperscale AI and HPC workloads, powered by the NVIDIA HGX B300 platform with dual Intel® Xeon® 6 processors. It supports 8x NVIDIA Blackwell Ultra GPUs for 72 PFLOPS FP8 training and 144 PFLOPS FP4 inference, enabling large-scale GPU clusters for LLM training, agentic AI, and real-time video generation. Orderable now with deposits, expected delivery in late October 2025, it's ideal for data centers seeking air-cooled, production-ready AI acceleration. No standalone GPUs are included; it integrates 8x HGX B300 GPUs via the baseboard.
