About the Lenovo ThinkSystem SR780a V3 Neptune AI Server
The Lenovo ThinkSystem SR780a V3 is a high-performance AI server built on Lenovo's Neptune liquid-cooling technology, integrating eight SXM-form-factor accelerators with high-bandwidth interconnect for large-scale model training and inference. Direct warm-water liquid cooling enables sustained accelerator performance at high density while improving energy efficiency.
The platform pairs dual high-core-count processors with extensive DDR5 memory and Gen5 NVMe storage to keep the GPU complex fed during demanding workloads. Designed for AI clusters, it supports high-speed fabric networking for GPU-direct communication across nodes.
Ideal for
- Large-model AI training and fine-tuning
- High-throughput AI inference at scale
- HPC and scientific simulation
- Generative-AI and LLM workloads
- GPU-accelerated research clusters
