Lenovo ThinkSystem SR680a V3 Rack Server — Product Overview & Specifications
Product Overview
The Lenovo ThinkSystem SR680a V3 is a powerful 8U rack server purpose-built for the most demanding AI and high-performance computing (HPC) workloads. It is designed fully in-house by Lenovo to deliver best-in-class modularity, thermal performance, and reliability.
The system is built around two 5th Gen Intel Xeon Scalable processors and supports up to eight high-performance NVIDIA GPUs with high-speed interconnects. This air-cooled server is engineered as an optimal platform for generative AI, featuring advanced GPU-to-GPU communications and high-speed PCIe 5.0 connectivity between GPUs, processors, and networking components.
The SR680a V3 delivers massive computational performance for AI workloads including large language model (LLM) training and inference, machine learning, modeling, simulation, rendering, financial technology, and scientific research. With support for NVIDIA H100, H200, and B200 GPUs, it provides the accelerated computing density required for elastic data centers and production AI deployments.
