摘要： An automated method and system are provided for facilitating monitoring of energy usage within a data center. The method includes automatically determining energy usage of one or more electronics racks of a data center by automatically ascertaining time-based energy usage of the electronics racks. The automatically ascertaining includes obtaining multiple measurements of instantaneous energy usage by each of the electronics racks in the data center over a period of time, and then separately averaging the multiple measurements for each electronics rack to obtain the time-based energy usage of each electronics racks. The method also includes outputting the time-based energy usage of the electronic(s) racks to facilitate monitoring of the data center.

摘要： Apparatuses and methods are presented for adjusting coolant flow resistance through one or more liquid-cooled electronics racks. Flow restrictors are employed in association with multiple heat exchange tube sections of a heat exchange assembly, or in association with a plurality of coolant supply lines or coolant return lines feeding multiple heat exchange assemblies. Flow restrictors associated with respective heat exchange tube sections (or respective heat exchange assemblies) are disposed at the coolant channel inlet or coolant channel outlet of the tube sections (or of the heat exchange assemblies). These flow restrictors tailor coolant flow resistance through the heat exchange tube sections or through the heat exchange assemblies to enhance overall heat transfer within the tube sections or across heat exchange assemblies by tailoring coolant flow. In one embodiment, the flow restrictors tailor a coolant flow distribution differential across multiple heat exchange tube sections or across multiple heat exchange assemblies.

The hoses are sufficiently long and flexible to open or close the door. A stress relief structure is attached to the top of the door and clamps the supply and return hoses in fixed relation to relieve stress on connect couplings at the ends of the hoses to the plenum inlet and outlet during opening or closing of the door.

摘要： A method, system, and computer program product for controlling data center cooling. In an example embodiment the method includes calculating, using a processor, an over-provisioning factor, where the over-provisioning factor is a function of a ratio of a rated cooling power to a calculated cooling power of a set of cooling units, the set of cooing units comprising at least one cooling unit. The method proceeds by adjusting the data-center cooling until the over-provisioning factor is substantially equal to a target over-provisioning factor.
