Patent number: 8789384Abstract: Embodiments of the present invention include a cooling system and method for cooling a computer rack by circulating liquid coolant through different sections of a rack heat exchanger under separately controlled flow and temperature conditions. In a method according to one embodiment, a first liquid coolant is supplied to a first section of an air-to-liquid heat exchanger. A second liquid coolant is supplied to a second section of the air-to-liquid heat exchanger at a different temperature than the first liquid coolant. Airflow is generated through rack-mounted computer components to the first and second sections of the air-to-liquid heat exchanger. The flow rates of the first and second liquid coolants are independently controlled to enforce a target cooling parameter. The independent operation of the first and second fin tube sections allows for the increased use of un-chilled water without sacrificing heat removal objectives.Type: GrantFiled: March 23, 2010Date of Patent: July 29, 2014Assignee: International Business Machines CorporationInventors: Eric A. Eckberg, Vinod Kamath, Howard V. Mahaney, Jr., William M. Megarity, Mark E. Steinke

Publication number: 20140164814Abstract: A computer determines a characteristic corresponding to each of a first power source and a second power source. The first and second power sources are connected to one or more power distribution units and are configured to provide power in a datacenter. The characteristic includes at least one of a current, a resistance, a voltage, a frequency, a phase, and a magnetic field. The computer generates a comparison of the characteristic corresponding to the first power source and the second power source, to a threshold value of the characteristic. The computer determines if the comparison violates the threshold value of the characteristic. In response to determining the comparison does not violate the threshold value of the characteristic, the computer determines that the first power source and the second power source are connected to a given power distribution unit included in the one or more power distribution units.Type: ApplicationFiled: December 7, 2012Publication date: June 12, 2014Applicant: International Business Machines CorporationInventors: John A.
