Techniques and systems for a semiconductor laser, namely a grating-coupled surface-emitting (GCSE) comb laser, having thermal management for facilitating dissipation of heat, integrated thereon. The thermal management is structured in manner that prevents deformation or damage to the GCSE laser chips included in the semiconductor laser implementation. The disclosed thermal management elements integrated in the laser can include: heat sinks; support bars; solder joints; thermal interface material (TIM); silicon vias (TSV); and terminal conductive sheets. Support bars, for example, having the GCSE laser chip positioned between the bars and having a height that is higher than a thickness of the GCSE laser chip. Accordingly, the heat sink can be placed on top of the support bars such that heat is dissipated from the GCSE laser chip, and the heat sink is separated from directed contact with the GCSE laser chip due to the height of the support bars.

Thermal management for hybrid lasers

Example computer racks to improve environmental sustainability in data centers are disclosed. An example computer rack includes a spine (); a first set of support structures () and a second set of support structures () extending from the spine (). Each of the support structures () is positioned to receive a respective blade. A first communication port is carried by the spine () and associated with the first set of support structures (). A second communication port is carried by the spine () and associated with the second set of support structures ().

A virtual power infrastructure for managing distribution of power to a plurality of power demanding units from a plurality of power generators includes a demand manager having logical descriptions of the power demanding units, in which the demand manager is configured to determine power load demands of the power demanding units using the logical descriptions of the power demanding units, and a capacity manager having logical descriptions of the power generators. The capacity manager is configured to determine allocation of power capacity supplied to the power generators from one or more of the power generators to meet the power load demands of the power demanding units, while satisfying one or more predetermined constraints associated with at least one of the power demanding units and the power generators.

Management of a virtual power infrastructure

A system and method for manipulating environmental conditions in an infrastructure containing a fluid moving device are disclosed that include identifying correlations between operational settings of the fluid moving device and environmental conditions resulting from changes to the operational settings. In addition, an environmental condition detected at a location proximate to or within the plenum following supply of fluid into the plenum by the fluid moving device is received and errors between the received environmental condition and a reference environmental condition are identified. Operational settings for the fluid moving device to achieve the reference environmental condition are determined based upon the identified correlations and errors.

Manipulating environmental conditions in an infrastructure

In a method for managing an infrastructure housing a plurality of disaggregated heat sources, in which a first disaggregated heat source has different heat dissipation characteristics as compared with a second disaggregated heat source, cooling requirements for the disaggregated heat sources are determined, in which the first disaggregated heat source and the second disaggregated heat source are to be positioned in separate homogeneous zones of the infrastructure. In addition, a respective available cooling resource is associated with the disaggregated heat sources based upon the determined cooling requirements of the disaggregated heat sources.

Managing an infrastructure housing disaggregated heat sources

Systems and methods to condition air are disclosed. An example system includes a desiccant heat transfer device to supply conditioned air to a facility, an air intake to receive air to be conditioned via the desiccant heat transfer device, and a make-up exhaust to provide exhaust air from a heat dissipating device in the facility to provide heated air to reactivate the desiccant heat transfer device.

In a method of synthesizing components to design a system meeting an exergy loss target value, one or more candidate sets of components are synthesized and an exergy loss value for each of the one or more candidate sets of components are calculated. A determination as to whether at least one of the candidate set of components meets the exergy loss target value is made and at least one candidate set of components determined to meet the exergy loss target value is identified as the set of components for use in the design of the system.

System synthesis to meet exergy loss target value

A method for integrating information technology (IT) data with non-IT data, comprising: first identifying a non-IT network for accessing non-IT data, second identifying an IT network from which to access the non-IT data from the non-IT network, first determining that the non-IT network is accessible via at least one interface based on Object Linking and Embedding for Process Control (OPC) for accessing at least one device in the non-IT network, second determining that the IT network includes an architecture for Simple Network Management Protocol (SNMP) or Web Based Enterprise Management (WBEM) for managing at least one device in the IT network, and providing the IT network with access to data of the at least one device in the non-IT network by accessing the at least one OPC-based interface via either the SNMP-capable architecture or the WBEM architecture of the IT network.

Managing power and performance

An automated test method characterizes the performance of commercially available thermal interface materials (TIM) for electronic cooling. Such automated internal test vehicle provides an independent study of various TIM's. A spectrum of materials are preferably tested using automated methods so the results are reported in a consistent way. Such reports simplify the comparison and selection of appropriate TIM material for various end-user applications. Such automated test method is observed to be faster and easier to use. It requires minimal operator intervention during the test.
