Energy Efficient Thermal Management of Data Centers examines energy flow in today's data centers. Particular focus is given to the state-of-the-art thermal management and thermal design approaches now being implemented across the multiple length scales involved. The impact of future trends in information technology hardware, and emerging software paradigms such as cloud computing and virtualization, on thermal management are also addressed. The book explores computational and experimental characterization approaches for determining temperature and air flow patterns within data centers. Thermodynamic analyses using the second law to improve energy efficiency are introduced and used in proposing improvements in cooling methodologies. Reduced-order modeling and robust multi-objective design of next generation data centers are discussed.

The Brief discuss primarily two aspects of air flow management in raised floor data centers. Firstly, cooling air delivery through perforated tiles will be examined and influence of the tile geometry on flow field development and hot air entrainment above perforated tiles will be discussed. Secondly, the use of cold aisle containment to physically separate hot and cold regions, and minimize hot and cold air mixing will be presented. Both experimental investigations and computational efforts are discussed and development of computational fluid dynamics (CFD) based models for simulating air flow in data centers is included. In addition, metrology tools for facility scale air velocity and temperature measurement, and air flow rate measurement through perforated floor tiles and server racks are examined and the authors present thermodynamics-based models to gauge the effectiveness and importance of air flow management schemes in data centers.

This book describes the use of free air cooling to improve the efficiency of, and cooling of, equipment for use in telecom infrastructures. Discussed at length is the cooling of communication installation rooms such as data centers or base stations, and this is intended as a valuable tool for the people designing and manufacturing key parts of communication networks. This book provides an introduction to current cooling methods used for energy reduction, and also compares present cooling methods in use in the field. The qualification methods and standard reliability assessments are reviewed, and their inability to assess the risks of free air cooling is discussed. The method of identifying the risks associated with free air cooling on equipment performance and reliability is introduced. A novel method of assessment for free air cooling is also proposed that utilizes prognostics and health management (PHM). This book also: Describes how the implementation of free air cooling can save energy for cooling within the telecommunications infrastructure. Analyzes the potential risks and failures of mechanisms possible in the implementation of free air cooling, which benefits manufacturers and equipment designers. Presents prognostics-based assessments to identify and mitigate the risks of telecommunications equipment under free air cooling conditions, which can provide the early warning of equipment failures at operation stage without disturbing the data centers' service. Optimum Cooling for Data Centers is an ideal book for researchers and engineers interested in designing and manufacturing equipment for use in telecom infrastructures.

The energy consumption issue in distributed computing systemsraises various monetary, environmental and system performanceconcerns. Electricity consumption in the US doubled from 2000to 2005. From a financial and environmental standpoint,reducing the consumption of electricity is important, yet thesereforms must not lead to performance degradation of the computingsystems. These contradicting constraints create a suite ofcomplex problems that need to be resolved in order to lead to'greener' distributed computing systems. This book bringstogether a group of outstanding researchers that investigate thedifferent facets of green and energy efficient distributedcomputing. Key features: One of the first books of its kind Features latest research findings on emerging topics bywell-known scientists Valuable research for grad students, postdocs, andresearchers Research will greatly feed into other technologies andapplication domains

Detailing powerful methods for reducing the energy costs associated with operating a data center, Making Your Data Center Energy Efficient examines both equipment and building facilities. It reviews the rationale for conserving energy and demonstrates how conservation and careful equipment selection can lead to significant improvements to your bottom line. For those not well-versed in financial or energy terms, the first two chapters provide a detailed discussion of the terms associated with different types of energy, as well as how to compute the return on investment for energy conservation efforts. The text includes tables of monthly expenses associated with operating equipment that will help you convert problems into simple table lookup processes. Among the money-saving topics discussed, it considers: How to minimize the energy consumption of a wide range of devices A little-understood topic that can make a big impact on energy costs—general heating and cooling Techniques required to effectively monitor different types of meters Phantom energy usage and methods for minimizing its cost to your organization Recognizing that most readers may not have direct control over the selection of a furnace or hot water heater, the book provides you with the ability to recognize the efficiencies and inefficiencies of various types of devices, so you can provide input into the decision-making process. From replacing lighting to consolidation and virtualization, it provides you with the well-rounded understanding needed to properly manage all aspects of the energy consumed in your data center.

Abstract: With the increase in electronic traffic, heat generated by electronic equipment, and the concomitant costs of powering cooling systems in electronic data centers are increasing continually. Various research groups working in academic institutions, research laboratories and industries have been applying a variety of tools to study and improve performance of data centers. This paper reviews recent contributions to the state of knowledge in data center thermal management. First, we review numerical and experimental studies on the most common air-cooled raised floor plenum type data centers. We then summarize published research on rack layout, efficiency and performance metrics for data centers, dynamic control and life cycle analyses, and validation of numerical models. Finally, we review some recently proposed cooling strategies and numerical optimization efforts. We find that the research carried out on thermal management of data centers has helped improve performance in many instances (such as rear door water cooled heat exchanger type rack), and has helped establish some physics-based criteria for data center designers. Based on the trends observed in this review, we expect further improvements to all aspects of data center design and operation in the near future, with a focus on real-time measurement & control, model validation and heuristics based optimization. In addition, some significant changes such as thermal energy storage and smart-grid capabilities are also expected to be incorporated into data center control strategies. Highlights: This paper reviews recent contributions to the state of knowledge in data center thermal management from 2007 to 2014. First, we review numerical and experimental studies, and then summarize published research on rack layout, efficiency and performance metrics for data centers, dynamic control and life cycle analyses, and validation of numerical models, some recently proposed cooling strategies and numerical optimization efforts. We find that these researches have helped improve performance and to establish some physics-based criteria for data center designers. We expect further improvements to all aspects of data center design and operation in the near future, with a focus on real-time measurement & control, model validation and heuristics based optimization.
