Practical Considerations - Refurbished Lenovo ThinkSystem GPU Servers
1. Cooling and Airflow
High-end GPUs produce significant heat. Ensure proper airflow, fan upgrades, and heatsinks for 300W+ GPUs. The Lenovo ThinkSystem SR670 V2 benefits from optimized air ducts; third-party liquid cooling is optional but not standard.
2. Power Supplies
Lenovo ThinkSystem SR650 V2 → Dual 1600W recommended for multi-GPU loads
Lenovo ThinkSystem SR670 V2 → Dual 1600W or higher for A100/H100 configurations
Lenovo ThinkSystem SE350 → Optimized for lower power GPUs
Check PCIe 8-pin or 12-pin connectors for GPU compatibility.
3. PCIe Bandwidth
Lenovo ThinkSystem SE350: PCIe Gen3 (limited for top GPUs)
Lenovo ThinkSystem SR650 V2: PCIe Gen4 x16 slots (good for inference)
Lenovo ThinkSystem SR670 V2: Full PCIe x16 lanes per GPU (best for training)
4. CPU and Memory
Use Intel Xeon Gold or Platinum CPUs. At least 256GB RAM for moderate AI workloads, 512GB–1TB for deep learning. NVMe SSDs and RAID help handle large datasets.
5. Networking and Expansion
For distributed training, 100GbE or InfiniBand is ideal. SR670 V2 supports GPU-to-GPU NVLink bridges for faster data exchange
