There is a growing consensus that conventional legacy data center design will be superseded by modular scalable data center designs. Reduced total cost of ownership, increased flexibility, reduced deployment time, and improved efficiency are all claimed benefits of modular scalable designs. Yet the term “modular”, when and where modularity is appropriate, and how to specify modularity are all poorly defined. This paper creates a framework for modular data center architecture and describes the various ways that modularity can be implemented for data center power, cooling, and space infrastructure and explains when the different approaches are appropriate and effective.
