Abstract: A cooling apparatus for a container-based data center comprises an air handling housing, at least one movable louver, a filter and a fan. The housing is configured for suspending from a ceiling of the container and comprises at least one heat exchanger. The louver is movable to direct air flow along different paths within the housing according to a selected operating mode. The fan is positioned in the housing and controllable according to the selected operating mode. The heat exchanger is configured in a self-contained water chilling circuit positioned within the container for use in a closed loop mode. The apparatus is convertible for use in an economizer mode that draws outside air into the container. An optional auxiliary heat exchanger element has a cold side heat exchange portion positioned outside the container and a connection through the ceiling to a hot side heat exchange portion positioned within the housing.

For at least one of the groups, a power-pooling bus element of at least one shelf-mountable electrical systems is electrically coupled to a power pooling bus element of at least one other of the shelf-mountable electrical systems in the group such that the power-pooling bus elements form an inter-shelf power-pooling bus for one or more of the computing devices in the group.

Abstract: A power busway interposer enables a power busway assembly of energized busway segments to be extended, via coupling additional busway segments to the assembly, while maintaining energization of the assembly. As a result, a power busway assembly providing power support to electrical loads can be extended while maintaining power support to the electrical loads. The interposer includes separate sets of connectors that couple with separate busway segments and a switching device which selectively electrically couples the connectors, so that a power busway connector can be de-energized while another separate power busway connector is coupled to an energized busway segment and then subsequently energized.

Abstract: A computer system includes a chassis, one or more hard disk drives coupled to the chassis, and one or more air passages under at least one of the hard disk drives. The air passages include one or more air inlets and one or more air outlets. The inlets direct at least a portion of the air downwardly into the passages. The passages allow air to move from the air inlets to the air outlets.

Abstract: An inverted exhaust plenum module exhausts air from an enclosure into an ambient environment while mitigating airflow restrictions caused by ambient wind conditions, particularly headwinds impinging on exhaust vents. The plenum module includes wall elements that extend downwards from separate edges of two separate roof elements of the enclosure, forming a plenum between the wall elements that is open at the top. Exhaust vents in the wall elements exhaust air from the enclosure into the plenum to circulate into the ambient environment via the top of the plenum. By exhausting air into a plenum that extends beneath roof elements, the vents are at least partially obscured from ambient winds that might otherwise impinge on the vents. A wing element can be installed to induce exhaust airflow via lowering air pressure at the top of the plenum. The plenum module can be a separate module that is coupled to a structure.

Abstract: A system includes a rack, computing devices coupled to the rack, a rack PDU, and one or more input power cables. The rack PDU includes an enclosure, two or more power input receptacles on the enclosure, and two or more power output receptacles on the enclosure. The output power receptacles supply power to the computing devices. The input power cables are coupled in one or more of the power input receptacles. The input power cables supply electrical power from an electrical power system to the rack PDU.

Abstract: A virtual temperature monitoring system in a data center communicates with servers mounted in racks to receive internal temperature data generated by internal temperature sensors of the servers. The system derives a virtual sensor measurement of external temperatures external to the server, including a portion of a cold aisle that extends proximate to a rack in which the server is mounted, based upon a relationship between the received internal temperature sensors and the external environment. Sensor data from other sensors can be received via a building management system, and building management signals to the building management system can be generated based at least partially on the virtual sensor data. The virtual sensor data can be used to generate a graphical representation of the servers that highlights relative thermal characteristics of the servers based on the virtual external sensor measurements, including heat indices, excursions beyond thresholds, historical excursion histories, etc.

Abstract: A data center row infrastructure module enables rapid deployment of a computing room enclosure for computer systems that provides intake air circulation to, and exhaust air removal from, the computer systems in the enclosure. The data center row infrastructure module includes free-standing exhaust plenum structures encompassing opposite sides of the enclosure and a plenum module spanning a top end of the enclosure between the free-standing exhaust plenum structures. Each free-standing exhaust plenum structure includes an internal exhaust air plenum that directs exhaust air received from the enclosure through an exhaust air outlet on a top end of the free-standing exhaust plenum structure. The plenum module establishes a bottom end of a cooling air plenum above and separate from the enclosure and between the free-standing exhaust plenum structures. Some plenum modules can direct cooling air directly to the enclosure as intake air.
