This book was released on 2009-01-01 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of computer rooms and telecommunications facilities is different in fundamental ways from the design of facilities used primarily for human occupancy. ASHRAE has not, until now, published a basic reference text to provide an overview of the special design needs of datacom facilities. As the power density of datacom equipment continues to increase, this need has grown more severe. This book covers basic design considerations for data and communications equipment centers. The book is divided into two parts. Part I, Datacom Facility Basics, includes chapters on datacom design criteria (temperature, temperature rate of change, relative humidity, dew point, and filtration), HVAC load, computer room cooling (including both air and liquid cooling), and air distribution. Part II of the book, Other Considerations, includes chapters on ancillary spaces (battery plants, emergency generator rooms, burn-in rooms and test labs, and spare parts rooms), contamination, acoustical noise emissions, structural and seismic design and testing, fire detection and suppression, commissioning, availability and redundancy, and energy efficiency. This book does not cover electrical or electronic systems design and distribution. The primary changes for this second edition center on the updated thermal envelope and relate to the recommended temperatures at the inlets of the equipment operating in datacom facilities. This book is the third in the ASHRAE Datacom Series, authored by ASHRAE Technical Committee 9.9, Mission Critical Facilities, Technology Spaces and Electronic Equipment. This series provides comprehensive treatment of datacom cooling and related subjects.

Available in PDF, EPUB and Kindle. Book excerpt: There is often a mismatch of IT equipment environmental requirements with adjacent equipment requirements or with facility operating conditions and therefore a strong need to find common solutions and standard practices that facilitate IT equipment interchangeability while preserving industry innovation. Thermal Guidelines for Data Processing Environments provides a framework for improved alignment between IT equipment hardware manufacturers (including manufacturers of computers, servers, and storage products), data center designers, and facility operators and managers. This guide covers five primary areas: equipment operating environment guidelines for air-cooled equipment (six classes are defined), environmental guidelines for liquid-cooled equipment (five classes are defined), facility temperature and humidity measurement (to evaluate data center health), equipment placement and airflow patterns (a hot-aisle/cold-aisle layout is recommended), and equipment manufacturers' heat load and airflow requirements reporting. In reaction to the industry trend of increased energy efficiency for data center operation, this third edition of Thermal Guidelines for Data Processing Environments provides groundbreaking, vendor-neutral information that will empower data center designers, operators, and managers to better determine the impact of varying design and operation parameters. This book is the first in the ASHRAE Datacom Series, authored by ASHRAE Technical Committee 9.9, Mission Critical Facilities, Technology Spaces and Electronic Equipment. This series provides comprehensive treatment of datacom cooling and related subjects.

Available in PDF, EPUB and Kindle. Book excerpt: A new approach to safety, based on systems thinking, that is more effective, less costly, and easier to use than current techniques. Engineering has experienced a technological revolution, but the basic engineering techniques applied in safety and reliability engineering, created in a simpler, analog world, have changed very little over the years. In this groundbreaking book, Nancy Leveson proposes a new approach to safety—more suited to today's complex, sociotechnical, software-intensive world—based on modern systems thinking and systems theory. Revisiting and updating ideas pioneered by 1950s aerospace engineers in their System Safety concept, and testing her new model extensively on real-world examples, Leveson has created a new approach to safety that is more effective, less expensive, and easier to use than current techniques. Arguing that traditional models of causality are inadequate, Leveson presents a new, extended model of causation (Systems-Theoretic Accident Model and Processes, or STAMP), then shows how the new model can be used to create techniques for system safety engineering, including accident analysis, hazard analysis, system design, safety in operations, and management of safety-critical systems. She applies the new techniques to real-world events including the friendly-fire loss of a U.S. Blackhawk helicopter in the first Gulf War; the Vioxx recall; the U.S. Navy SUBSAFE program; and the bacterial contamination of a public water supply in a Canadian town. Leveson's approach is relevant even beyond safety engineering, offering techniques for “reengineering” any large sociotechnical system to improve safety and manage risk.
