ASHRAE SERVER EFFICIENCY
Server Efficiency - Metrics for Computer Servers and Storage
|Publication Date:||1 January 2015|
Advanced computing technologies have allowed businesses, governments, academia, and other organizations to greatly improve and expand their use of information to enhance the ability to achieve their goals. However, with expanded use of data comes an expansion of data processing equipment-in processing power, in data storage, and in supporting components -along with a potential expansion in the physical and air-handling facilities needed to house the equipment. Coupling this expansion with increasing costs of the energy needed to power the equipment and potential restrictions in the amount of energy that is actually available for use yields a substantial need for energy efficiency in the data center.
As evidenced by other books from ASHRAE's Datacom Series, there are many areas where energy efficiency can be addressed. A key component of any energyefficiency effort has to be the base efficiency of the actual data processing equipment involved.
Energy efficiency has been an increasing concern of computer hardware and software designers for several years, with very positive results. Examples include innovations to allow solid-state drives to replace rotating storage devices, higher density memory, increased computing capacity within a single footprint, firmware with a power management focus, and improved virtualization techniques that allow multiple computing images to reside on a single server. Despite this, in today's world of tightly controlled budgets, "new and improved" is an insufficient argument for investing in new hardware or software that provides better energy efficiency. Metrics and measures are required to indicate the relative worth of the investment. Ideally, these measures should be standardized across the industry, to ensure consistency for those evaluating them.
With this addition to the Datacom Series, ASHRAE is providing a much needed overview of the tools that are available to quantify energy consumption of computing equipment. Cursory descriptions of these tools have been made into industry presentations and papers, but this is the first in-depth description of a wide variety of computing energy-efficiency measures in a single source.
These measurement tools are, of course, useful to computer
hardware and software manufacturers-provid
Using this book, data processing managers could even go one or two steps further, by either selecting a tool for measurements within their own facilities, or even by creating a new tool using the guidelines set forth in this book.
I congratulate the members of ASHRAE, the authors, and the editors for providing this collection and I look forward to it being used to further energy-efficiency improvements and to help those investing in computing technology to make informed decisions.
