What hardware and networking does a GPU compute cluster require?

Core cluster hardware: H100/A100 GPU servers, InfiniBand switches (400Gbps NDR for H100), storage nodes (NVMe SSDs forming a parallel file system) and management nodes. On the network side, GPU servers must be interconnected through InfiniBand to unleash multi-GPU parallel training — ordinary Ethernet latency is too high and becomes the bottleneck. ZhongLianDa provides end-to-end service from hardware selection and cluster build-out to scheduler deployment, proposing minimum and recommended configurations based on your model size.
