20130037254 | Data Center With Low Power Usage Effectiveness - A system for providing cooled air to electronic equipment includes a data center having electronic equipment in operation, a plurality of on-floor cooling units, and a cooling water source. The on-floor cooling units cool air warmed by the electronic equipment. The cooling water source is configured to supply cooling water that reduces a temperature of the on-floor cooling units. The power usage effectiveness (“PUE”) of the system is less than 1.3, wherein the PUE is defined by energy used to operate the data center divided by energy used to run the electronic equipment. | 02-14-2013 |
20130025842 | Warm Water Cooling - A method of providing cooled air to electronic equipment includes capturing heated air from a volume containing electronic equipment, cooling the heated air by more than fifteen degrees Celsius in an air-to-water heat exchanger, and supplying cooling water to the air-to-water heat exchanger at a temperature above a dew point temperature of the heated air. | 01-31-2013 |
20120138259 | Data Center Cooling - A system for cooling air in a data center includes a data center having electronic equipment in operation, a cooling water source, and a plurality of on-floor cooling units. The cooling water source is configured to retain at maximum capacity a total amount of water. Each on-floor cooling unit is configured to cool air heated by a portion of the electronic equipment in the data center using water from the cooling water source. The total amount of water is insufficient to maintain a leaving air temperature of each on-floor cooling unit below an inside setpoint when a temperature outside of the data center is above a predetermined external temperature. | 06-07-2012 |
20110239671 | Blended Water-Based Data Center Cooling - A method of providing cooling by a cooling system to a computer data center. The method includes providing a plurality of air-and-water radiators and one or more chillers, the chillers each having a first side in fluid communication with a chilled water loop and a second side in communication with a condenser water loop. The method also includes circulating a first portion of return water coming from the computer data center to a first subset of the air-and-water radiators and through the condenser water loop, circulating a second portion of the return water from the computer data center to a second subset of the air-and-water radiators and through the chilled water loop, and circulating the first portion and the second portion of the return water to the computer data center as cooled supply water. | 10-06-2011 |
20110207391 | Controlled Warm Air Capture - A system for providing air circulation to rack-mounted computers can include a plurality of rack-mounted computers on a plurality of motherboards, each motherboard having a front end near a work space and a back end; one or more fans associated with the plurality of motherboards and adapted to deliver heated air from the computers to a common warm-air plenum; and one or more motor controllers coupled to the plurality of fans and adapted to maintain a substantially constant sensed exhaust temperature for air moved by the fans. | 08-25-2011 |
20110174001 | Warm Water Cooling - A method of providing cooled air to electronic equipment includes capturing heated air from a volume containing electronic equipment, cooling the heated air by more than fifteen degrees Celsius in an air-to-water heat exchanger, and supplying cooling water to the air-to-water heat exchanger at a temperature above a dew point temperature of the heated air. | 07-21-2011 |

The on-floor cooling units cool air warmed by the electronic equipment. The cooling water source is configured to supply cooling water that reduces a temperature of the on-floor cooling units. The power usage effectiveness (“PUE”) of the system is less than 1.3, wherein the PUE is defined by energy used to operate the data center divided by energy used to run the electronic equipment. | 05-05-2011 |
20110100045 | Data Center Cooling - A system for cooling air in a data center includes a data center having electronic equipment in operation, a cooling water source, and a plurality of on-floor cooling units. The cooling water source is configured to retain at maximum capacity a total amount of water. Each on-floor cooling unit is configured to cool air heated by a portion of the electronic equipment in the data center using water from the cooling water source. The total amount of water is insufficient to maintain a leaving air temperature of each on-floor cooling unit below an inside setpoint when a temperature outside of the data center is above a predetermined external temperature. | 05-05-2011 |
20110078435 | Updating a Power Suppy Microcontroller - A system is described that includes a power conversion module, a data port, a controller to receive data from the data port, and a data store containing instructions that when executed by the controller perform operations to control the power conversion module. The operations include executing instructions in a first portion of the data store during booting of the controller, executing instructions in a second portion of the data store after the controller has booted, receiving a signal from the data port indicating the instructions in the second portion are to be modified, receiving from the data port modified instructions to be stored in the second portion, and executing, in response to the signal, the instructions in the first portion to store the modified instructions in the second portion. | 03-31-2011 |
20100085196 | DATA CENTER THERMAL MONITORING - A measurement indicative of a temperature of a computer is received and a thermal health value for the computer is calculated based on the measurement. | 04-08-2010 |
20090206670 | Data Center Uninterruptible Power Distribution Architecture - Apparatus and associated method and computer program products involve a highly efficient uninterruptible power distribution architecture to support modular processing units. As an illustrative example, a modular processing unit includes an corresponding uninterruptible power system in which only one AC-to-DC rectification occurs between the utility AC grid and the processing circuit (e.g., microprocessor) loads. In an illustrative data center facility, a power distribution architecture includes a modular array of rack-mountable processing units, each of which has processing circuitry to handle network-related processing tasks. Associated with each modular processing unit is an uninterruptible power supply (UPS) to supply operating power to the network processing circuitry. Each UPS includes a battery selectively connectable across a DC bus, and a AC-to-DC rectifier that converts an AC input voltage to a single output voltage on the DC bus. The regulated DC bus voltage may be close to the battery's fully charged voltage. | 08-20-2009 |
