This paper demonstrates an environmental friendly methodology for implementing an air conditioning or refrigeration system. In particular, the cooler does not deplete the earth's limited fossil fuel reserves nor does it harm the global environment either by depleting stratospheric ozone or by contributing to global warming through the emission of greenhouse gases. The electrical energy input needed...
The demand for data center solutions with lower total cost of ownership and lower complexity of management is driving the creation of next generation datacenters. The information technology industry is in the midst of a transformation to lower the cost of operation through consolidation and better utilization of critical data center resources. Successful consolidation necessitates increasing utilization...
In this paper, we propose a methodology for real-time characterization of the operational state of a subsystem, device or process in an ecosystem, with the goal of improving its sustainability. The objective is to re-describe the operational state, identified by a set of relevant sensor measurements and other parameters, in terms of known operational patterns. Each pattern is also associated with...
Next generation data centers must be designed to meet service level agreements (SLAs) for application performance while reducing costs and environmental impact. Traditional design approaches are manually intensive and must integrate thousands of components at multiple granularities, often with conflicting goals. We propose an automated data center synthesizer to design sustainable data centers that...
The growing energy consumption of computer data centers has recently received increased economic and environmental scrutiny. A significant portion of typical data center energy consumption can be apportioned to the cooling infrastructure. This paper shows the impact of heat load within the data center on the efficiency of the data center cooling ensemble, as measured in terms of a 'grand' Coefficient...
