Supply chain constraints have emerged as critical bottlenecks for datacenter deployment, with GPU availability, electrical equipment shortages, and construction material delays creating multi-year lead times. The datacenter industry’s explosive growth has overwhelmed global manufacturing capacity across multiple critical components.

overview

GPU availability constraints

AI/ML demand explosion

GPU shortages represent the datacenter industry’s most acute supply chain challenge:

Market dynamics
