Clos Network Architecture: Cost and Selection Framework for AI Inference Clusters

By PulseAugur Editorial · [1 sources] ·

The Clos (or Fat-Tree) network architecture is a popular choice for large-scale AI inference clusters due to its scalability and high bandwidth. This article analyzes the cost components of Clos networks, including switches, cabling, and port density, particularly for clusters with thousands of GPUs. It also discusses the importance of considering operational expenses alongside initial hardware costs for a comprehensive Total Cost of Ownership (TCO) model, highlighting how efficient storage solutions can indirectly optimize network requirements. AI

    Clos Network Architecture: A Cost-Effectiveness and Selection Framework for Thousand-Card Inference Clusters

    <p>When building compute clusters for thousand-card scale large model inference tasks, the choice of network architecture directly determines the cluster's scalability, performance ceiling, and Total Cost of Ownership (TCO). The Clos (or Fat-Tree) network architecture, with its n…
