White Paper: Best Practices and Integration Strategies for XPU and 224Gbps in 3D Torus Rack-Level Topology

AI and large-language-model clusters are straining the limits of traditional fat-tree and star networks. When tens of billions of parameters move across 224 Gbps links, the switch tiers, cable count, and power draw all climb sharply. Our newest white paper explains how a 3D Torus rack-level fabric trims hop counts, shortens cable runs, and reduces switch silicon while preserving the low latency and massive bandwidth required by modern XPU fleets.

Inside the paper you will find head-to-head benchmarks of 3D Torus against Fully-Connected, Tree, and Dragonfly designs under tensor- and pipeline-parallel training. Detailed latency heat maps, watt-per-teraflop savings, and bill-of-materials comparisons show why a small-diameter torus consistently outperforms sprawling Clos fabrics. The guide also covers 224 Gbps SerDes layout, efficient rack wiring, and fault-tolerant routing so that architects can scale cleanly from a single rack to exascale pods.
