Problems solved by technology

Oftentimes, however, the temperatures detected at the air conditioning unit inlets are not an accurate reflection of the temperatures of the computer systems being cooled.
This type of cooling provisioning oftentimes leads to excessive and inefficient cooling solutions.
This problem is further exacerbated by the f

Embodiment Construction

[0018] For simplicity and illustrative purposes, the present invention is described by referring mainly to an exemplary embodiment thereof. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent however, to one of ordinary skill in the art, that the present invention may be practiced without limitation to these specific details. In other instances, well known methods and structures have not been described in detail so as not to unnecessarily obscure the present invention.

[0019] A system and method for commissioning sensors is disclosed herein. More particularly, the sensors may be related to a number of actuators, for instance, CRAC units. The relationships are described in terms of actuator families and the sensors are assigned to respective actuator families based upon the relative effects that each actuator has on each sensor. Thus, for instance, a sensor may be assigned to ...

Abstract

A method for commissioning sensors includes determining correlation data between the sensors and a plurality of actuators. The correlation data is based upon conditions detected by the sensors at a plurality of actuator settings. Correlation indexes are calculated from the correlation data, where a correlation index for a sensor is a function of the plurality of actuator settings and a particular actuator. In addition, each of the sensors is assigned to at least one of a plurality of actuator families based upon the calculated correlation indexes of the sensors to thereby commission the sensors.

Description

BACKGROUND [0001] A data center may be defined as a location, for instance, a room that houses computer systems arranged in a number of racks. A standard rack, for example, an electronics cabinet, is defined as an Electronics Industry Association (EIA) enclosure, 78 in. (2 meters) high, 24 in. (0.61 meter) wide and 30 in. (0.76 meter) deep. These racks are configured to house a number of computer systems, about forty (40) systems, with future configurations of racks being designed to accommodate 200 or more systems. The computer systems typically include a number of printed circuit boards (PCBs), mass storage devices, power supplies, processors, micro-controllers, and semi-conductor devices, that dissipate relatively significant amounts of heat during their operation. For example, a typical computer system containing multiple microprocessors dissipates approximately 250 W of power. Thus, a rack containing forty (40) computer systems of this type dissipates approximately 10 KW of pow...
