1. A control system for a data center having a cold air cooling system, a cold air containment structure receiving pressurized cold air from the cold air cooling system, and an air exhaust space, wherein information technology equipment (IT equipment) is provided within enclosures providing flow paths between the cold air containment structure and the air exhaust space, the control system comprising:
at least one input configured to receive information for determining at least an air pressure of the cold air containment structure and at least a pressure of the air exhaust space;
an output port configured to communicate a control signal to control at least one of a leakage device configured to control air flow across a boundary of the cold air containment structure, and a damper configured to restrict an air flow through the cold air containment structure; and
at least one processor, configured to:
receive the information from the at least one input;
determine an air flow through a plurality of IT equipment enclosures;
determine an insufficient cooling condition for at least one IT equipment enclosure; and
produce a control signal at the output port to control the leakage device, wherein the control signal is adapted to reduce a pressure in the cold air containment structure and thereby increase cooling of the at least one IT equipment enclosure for which the insufficient cooling condition is determined, the control signal conveying information to at least one of:
increase a leakage through the leakage device through a path excluding the at least one IT equipment enclosure for which the insufficient cooling condition is determined, and
restrict the air flow through the cold air containment structure with the damper.
