Abstract: A modular data center has an air handling unit (AHU) that is coupled to a first panel that is engaged over a first opening in a volumetric container. The AHU directs pressurized supply air through a supply air outlet into a cold aisle causing the supply air to pass through a first side of the IT component(s) installed in an interior of the volumetric container. A chimney of a return air plenum captures return air from a second side of the IT component(s), directing the return air to a return air duct of the return air plenum that is connected to a return air inlet of the AHU. In one or more embodiments, a second AHU is coupled to a second panel that is engaged to a second opening in a second side, directing pressurized supply air via a supply air plenum to the opposing first side.

Abstract: A modular data center (MDC) includes a volumetric container comprising an enclosure having first and second exterior walls at a forward and an aft end, connected by lateral exterior walls. Information technology component(s) are positioned longitudinally within the container between a cold aisle and a hot aisle. An air handling system includes two or more air handling units (AHUs) each having a return air inlet and a supply air outlet. A supply air plenum directs cooling air flow from the supply air outlets to a supply air opening positioned adjacent to the cold aisle. Backflow prevention mechanisms are positioned respectively at each supply air outlet of the AHUs. Each backflow prevention mechanism is moveable into an open position to allow cooling air flow out of the supply air outlet of a corresponding AHU and a closed position in response to deactivation of an air mover of the corresponding AHU.

Abstract: A data center provides containment walls of an operation technology (OT) interior compartment, such as a meet me room, positioned between cold and hot aisles in an information technology (IT compartment. The OT interior compartment limits air flow so that IT components outside of the OT interior compartment receive sufficient supply air for moderating or cooling a temperature of the IT components. Pressure differential is measured on an exterior and interior of door(s) to the OT interior compartment. Air flow regulation device(s) are positioned in a supply air passage to the OT interior compartment and/or in a return air passage out of the OT interior compartment are controlled to limit the pressure differential between an exterior and interior of the containment wall. Limiting the pressure differential ensures that door(s) facing the cold aisle are not difficult to open and door(s) facing the hot aisle are not difficult to close.

Abstract: An information handling system may include a direct-current power supply, a plurality of information handling resources configured to receive electrical energy from the direct-current power supply, a thermal control subsystem configured to regulate temperature within the information handling system, and a control subsystem configured to, when temperature proximate to at least one of the direct-current power supply and the plurality of information handling resources is outside of temperature specifications: isolate the direct-current power supply from a mains power source of the information handling system and deactivate the direct-current power supply to prevent delivery of electrical energy to the plurality of information handling resources.

Abstract: A multiple mode cooling system circulates outside air through a data center to cool heat-generating information technology (IT) component(s). Based on outside and interior air temperature values and outside humidity value, a controller determines that outside air cooling poses a risk of damage to the heat-generating IT component(s) due to condensation or overheating. Controller also determines that compressor(s) of the cooling system have been inactive for less than a minimum off-time specified for maintaining service life of the compressor(s). In response, controller checks a cooling mode setting and, based on determining that a cooling mode setting indicates an optimization preference for avoiding the posed risk of damage to the heat-generating IT component(s) over compressor service life, the controller restarts the compressor(s) before expiration of the minimum off-time.

Abstract: A modular data center (MDC) has a cooling unit externally positioned proximate to a first longitudinal external wall of a volumetric container. The cooling unit directs supply air sideways through a supply air opening into a cold aisle adjacent to the first longitudinal external wall. The cooling air passes through rack(s) containing information technology (IT) components to a hot aisle. A baffle positioned within the volumetric container above the rack(s) directs return air from the hot aisle through a return air plenum to a return air opening in the first longitudinal external wall. A shroud coupled to at least one of the volumetric container and the cooling unit receives the sideways directed return air and directs the return air downward into an upwardly open return air inlet of the cooling unit.
