Download and read online ebook Liquid Cooling Guidelines for Datacom Equipment Centers write by . This book was released on 2006. Liquid Cooling Guidelines for Datacom Equipment Centers available in PDF, EPUB and Kindle. Dual unitsData center IT equipment today is predominantly air cooled. However, with rack heat loads steadily climbing, the ability for many data centers to deliver either adequate airflow rates or sufficient chilled air is now being stretched to the limit. These trends in the heat load generated from IT equipment can have detrimental side effects, such as decresed equipment availability, wasted floor space, and inefficient cooling system operation. This situation is creating a need for implementing liquid cooling solutions. The overall goals of the liquid implementations include aspects such as trasferring as much waste heat to the facility liquid cooling loop as possible, reducing the overall volume of airflow needed by the racks, and reducing processor temperatures such that increased compute performance can be achieved.This book on liquid cooling is divided into six chapters and includes definitions for liquid and air cooling as it applies to the IT equipment, describing the various liquid loops that can exist in a building that houses a data center. It also provides the reader an overview of the chilled-water and condenser water systems and an overview of datacom equipment cooling options. The book also bridges the liquid cooling systems by providing guidelines on the interface requirements between the chilled-water system and the technology cooling system and outlines the requirements of those liquid-cooled systems that attach to a datacom electronics rack and are implemented to aid in data center thermal management.This book is the fourth in a series of datacom books published by ASHRAE and authored by TC 9.9, Mission Critical Facilities, Technology Spaces, and Electronic Equipment.

Data Center Handbook
Data Center Handbook - read free eBook in online reader or directly download on the web page. Select files or add your book in reader. Download and read online ebook Data Center Handbook write by Hwaiyu Geng. This book was released on 2014-12-22. Data Center Handbook available in PDF, EPUB and Kindle. Provides the fundamentals, technologies, and best practices in designing, constructing and managing mission critical, energy efficient data centers Organizations in need of high-speed connectivity and nonstop systems operations depend upon data centers for a range of deployment solutions. A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes multiple power sources, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and security devices. With contributions from an international list of experts, The Data Center Handbook instructs readers to: Prepare strategic plan that includes location plan, site selection, roadmap and capacity planning Design and build "green" data centers, with mission critical and energy-efficient infrastructure Apply best practices to reduce energy consumption and carbon emissions Apply IT technologies such as cloud and virtualization Manage data centers in order to sustain operations with minimum costs Prepare and practice disaster reovery and business continuity plan The book imparts essential knowledge needed to implement data center design and construction, apply IT technologies, and continually improve data center operations.

Download and read online ebook Design Considerations for Datacom Equipment Centers write by American Society of Heating, Refrigerating and Air-Conditioning Engineers. This book was released on 2009-01-01. Design Considerations for Datacom Equipment Centers available in PDF, EPUB and Kindle. 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.

Download and read online ebook Thermal Guidelines for Data Processing Environments write by ASHRAE (Firm). This book was released on 2012. Thermal Guidelines for Data Processing Environments available in PDF, EPUB and Kindle. 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.
