GPU-Era Datacenter Networks Ill-Suited for Inference-Heavy Workloads
May 25, 2026
AI training clusters require lossless, low-latency east-west fabric where network performance directly caps GPU utilization — a fundamentally different constraint than traditional north-south web traffic patterns. As inference workloads grow and GPU density shifts, datacenter network architecture assumptions built around training may not hold.
