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.
