NVIDIA HGX B200 8-GPU AI Server (Synthetic Mode DLC)
4U AI TRAINING / LLM / INFERENCE / HPC / LIQUID COOLING
The 4U8X-GNR2/DLC SYN B200 is a 4U rack-mount liquid-cooled AI server carrying the NVIDIA HGX B200 8-GPU module with NVIDIA NVSwitch for full-speed GPU-to-GPU interconnect. Direct liquid cooling (DLC) fits eight-GPU thermal capacity into 4U, raising rack power density while cutting fan noise and cooling energy. It runs dual Intel Xeon 6700P / 6500P / 6700E series processors with 32 DDR5 DIMM slots up to MRDIMM 8000 MT/s and ten rear PCIe 5.0 x16 expansion slots, suiting high-density AI training clusters and LLM inference services.
