The document discusses how standardization and modularity can make retrofitting data center infrastructure faster, cheaper, and easier. It outlines two approaches: 1) Using pre-engineered reference designs that simplify planning and reduce risk. 2) Implementing modular, standardized components like UPS batteries, wiring, and infrastructure pods that allow flexible scaling and easier maintenance. Modular designs allow adjustable capacity expansion, quick deployment, and continued flexibility over time. Overall, the rise of standardized modular solutions is revolutionizing retrofitting by driving down costs and complexity.
