Lenovo ThinkSystem SR680a V3
8U rack AI server built around eight NVIDIA H100, H200 (SXM5) or B200 (SXM6) GPUs with NVLink, driven by two 5th Gen Intel Xeon Scalable processors, for large-scale AI training and inference. The B200 configuration is a heavier-duty build with higher-wattage power supplies and no rear I/O, covered in a separate Lenovo Press guide.
