Lenovo ThinkSystem SR670 V2
The ThinkSystem SR670 V2 is Lenovo's modular 3U two-socket high-density GPU server engineered for artificial intelligence, machine learning deep training, high-performance computing (HPC), and graphical rendering clusters. Powered by 3rd Gen Intel Xeon Scalable (Ice Lake) processors, it features a modular chassis design with interchangeable front bays supporting either up to 8 full-height, double-width PCIe 4.0 GPUs or a 4-way NVIDIA HGX A100 SXM4 board with Lenovo Neptune hybrid liquid-to-air cooling. In the refurbished and enterprise surplus market, it is sought after for on-premises AI inference and fine-tuning. Buyers should carefully verify which GPU front bay module is installed, check power cabling harnesses, and inspect all four high-wattage power supplies.
