Abstract:
1. A data center system comprising: a plurality of computing assets included in a compartment, each computing asset having a first side oriented toward a cold aisle and having a second side oriented toward a hot aisle, the hot aisle having a lower pressure relative to the cold aisle so that air flows from the cold aisle to the hot aisle across the computing assets; a cold stack coupled to the cold aisle and comprising a cooling system, the air from outside the data center system entering the cold stack through an input and being cooled by the cooling system to a temperature lower than a temperature of the air outside the data center system, the cold stack having a height sufficient to cause air to flow through the cold stack when there is a temperature difference between the cooled air in the cold stack and the air outside the data center system, the rate of the air flow through the cold stack based on the height; a hot stack coupled to the hot aisle via an opening, the hot stack extending outside of the data center and having a height from the opening sufficient to, at a temperature difference between a temperature of air in the hot aisle and a temperature of the air outside to the data center, create a pressure difference that that causes air to flow from the hot aisle through the opening and into the hot stack.
