Abstract: A system for cooling a heat generating enclosure includes a first array of one or more fans of a first size and a second array of one or more fans of a second size, where the second array is in series to the first array. The system also includes a measuring unit configured to measure at least one process variable. The system also includes a control unit configured to control at least one of the fans in the first array or at least one of the fans in the second array based on the process variable, wherein the fans are controlled to achieve an optimization criterion.

Abstract: A method of cooling a heat generating enclosure includes setting a speed of each fan in a first array of fans, wherein each fan in the first array of fans is a first size, is disclosed. The method further includes measuring a process variable. The method also includes calculating a cooling strategy based at least in part on the value of the process variable. The method further includes setting the speed of each fan in the first array of fans or the speed of each fan in a second array of fans, wherein the second array of fans is in series to the first array of fans and each fan in the second array of fans is a second size, and wherein the speed of each fan that is set in the first or second array is set to implement the cooling strategy.

Abstract: A fan assembly system includes two or more circular fans, each fan situated in a round fan assembly, where each fan can be situated in the round fan assembly in any orientation. The system also includes a concentrically symmetric connector for each circular fan, located in a center of each circular fan. The system also includes a latching mechanism for each circular fan, where the latching mechanism is wholly contained within a swept area of a fan blade of the circular fan. The circular fans are arranged in a staggered arrangement, and the staggered arrangement of circular fans increases a number of circular fans that can be placed in the fan assembly system compared to a non-staggered arrangement.

Abstract: It is determined that a current node power consumption for a node is greater than a node power cap that defines a limit of power consumption for the node. Responsive to the current node power consumption being greater than the node power cap and until the current node power consumption is less than the node power cap, power reduction operations are performed. The power reduction operations comprise determining a power management zone of a plurality of power management zones having a lowest priority among the power management zones and having a power cap greater than a minimum power cap for the power management zone. The power reduction operations further comprise setting the power cap for the power management zone to a value less than a prior value assigned as the power cap for the power management zone.

Abstract: A zone power cap for a power management zone that defines a limit of power consumption for the power management zone is determined. The power management zone comprises a plurality of components, wherein the power management zone is associated with a controller. A set of one or more characteristics of a workload associated with the power management zone is determined. A component power cap for one or more of the plurality of components is set based, at least in part, on the set of one or more characteristics of the workload and the zone power cap.
