It covers design criteria, HVAC loads, cooling systems overview, air distribution and liquid cooling. It will also provides information that is supplemental to basic data center design, which may be of more value to those who already have design and/or operating experience in this field, covering additional topics such as ancillary spaces, contamination, acoustics, structural and seismic design, fire suppression, commissioning, availability and redundancy, and energy efficiency.

4. Liquid Cooling Guidelines for Datacom Equipment Centers, Second Edition

liquidcooing-100W.gifData 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 decreased 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.

5. Structural and Vibration Guidelines for Datacom Equipment Centers

datacom5-100W.jpgThis book discusses datacom equipment as well as a building's structure and infrastructure in a holistic way while providing best practices for their design and installation. The book is divided into four main sections.

Part 1, Introduction, gives an overview of the best practices in the design of datacom equipment centers, including recommendations for new and renovated building structures, building infrastructure, and datacom equipment. Part 2, Building Structure, covers the design of new and existing structures. In Part 3, Building Infrastructure, the structural considerations of the building's infrastructure, raised-access floor systems, and vibration sources and their control are discussed in detail. The last part of this book, Datacom Equipment, covers shock and vibration testing, seismic anchorage systems and analysis of datacom equipment.

7. High Density Data Centers - Case Studies and Best Practices

highdensity-100W.gifData centers and telecommunications rooms that house datacom equipment are becoming increasingly more difficult to adequately cool. This is a result of IT manufacturers increasing datacom performance year after year at the cost of increased heat dissipation. The power required and the resulting heat dissipated by the datacom equipment has increased to a level that is putting a strain on data centers.

This book provides case studies of high density data centers and a range of ventilation schemes that demonstrate how loads can be cooled using a number of different approaches.

9. Real-Time Energy Consumption Measurements in Data Centers

realtimeenergy-100W.jpgData centers are dense and complex environments that house a wide variety of energy consuming equipment. With information technology (IT) and facilities equipment, there are thousands of energy consumption monitoring points. If a data center operator cannot monitor a device, that device cannot be controlled. In addition, for a data center to reach its optimal energy efficiency, all equipment on the IT and facilities sides must be monitored and controlled as an ensemble. IT and facilities organizations in a company typically have different reporting structures, which results in a communication gap. This book is designed to help bridge that gap and provides an overview of how to instrument and monitor key power and cooling subsystems.

The book also includes numerous examples of how to use energy consumption data in calculating power usage effectiveness (PUE), along with a practical method that can be used to quantify the PUE for a data center housed in a mixed-use facility. Finally, some coverage is provided for a data center that deploys a combined cooling, heat, and power system. Calculating the PUE for such a data center presents some challenges; this book helps clarify the key issues.

10. Green Tips for Data Centers

10greentips-100W.jpgThe data center industry is focused on reducing energy - a focus driven by increasing energy costs and capital costs to add more data center capacity. Combined with rapid growth in the industry and the increase in power used by IT equipment, it is important that every data center operator understand the options for reducing energy. In the past, it was thought that the critical nature of data center technology did not allow for traditional energy-saving approaches and that data centers' continuous operation offered no "unoccupied" periods when energy could be saved. Today, however, there is recognition that energy can be saved in both the data center facility and the IT equipment.

This book gives data center owners and operators a clear understanding of energy-saving opportunities. It covers the mechanical and electrical systems of the building and also the most promising opportunities in technology. In addition, the book's organization follows a logical approach that can be used for conducting a preliminary energy assessment.
