Abstract: The vertical data center module is a multistory compact footprint data center unit that exploits vertical air movements, both downward and upward, to efficiently sustain conventional low-cost air-cooled computing systems. It integrates a hybrid cooling system that can benefit from an air-side economizer without compromising its compact footprint. For polluted urban environments, this air-side economizer comprises an air-to-air heat exchanger to effectively limit the amount of outside air that can enter the module and come into contact with sensitive computing systems. Through side-to-side, side-to-back or back-to-back juxtaposition, multiple units can be assembled in clusters on a colocation site to create large-scale vertical data center complexes, effectively maximizing real estate use and cost effectiveness by fully exploiting all three dimensions.

Abstract: A data center module is a data center that can be prefabricated using generally standardized off-the-shelf components, and quickly assembled on a collocation site where a shared central facility is provided. The data center module is typically configured to be deployed with other identical data center modules around the central facility both in side-to-side and/or in back-to-back juxtapositions, typically without the need for interleaving space between adjacent modules in order to maximize real estate use. Each data center module typically comprises harden party walls, several floors for accommodating all the necessary electrical and cooling subsystems and for accommodating all the computing machinery (e.g. servers). Though all the data center modules share similar physical configuration, each data center module can be independently customized and operated to accommodate different needs.
