THE DATA CENTER JOURNAL | 27 www.datacenterjournal.com list of aShrae tc9.9 Special Publications • Thermal Guidelines for Data Processing Environments, Third Edition, 2012 • Datacom Equipment Power Trends and Cooling Applications, Second Edition, 2012 • Design Considerations for Datacom Equipment Centers, Second Edition, 2009 • Liquid Cooling Guidelines for Datacom Equipment Centers, Second Edition, 2013 • Structural and Vibration Guidelines for Datacom Equipment Centers, 2009 • Best Practices for Datacom Facility Energy Efficiency, Second Edition, 2009 • High Density Data Centers – Case Studies and Best Practices, 2008 • Particulate and Gaseous Contamination in Datacom Environments, Second Edition, 2013 • Real-Time Energy Consumption Measurements in Data Centers, 2010 • Green Tips for Data Centers, 2010 • PUE: A comprehensive Examination of the Metric, 2013 • Data Center Essentials (a searchable pdf compilation of the 11 books listed above) • Server Energy Performance – Efficiency Metrics for Computer Servers and Storage Subsystems, 2015 (currently in final draft review and due for imminent release) e latest edition of Datacom Equipment Power Trends and Cooling Applications provides equipment power draw and density trends out to the year 2020 along with detailed methodology on how to use the trend data to allow data center designers to correctly plan and provision for the potential future growth of their facilities based on hardware technology advancements; an essential input for data center infra- structure design. e trends book publication, along with publications such as design consid- erations, best practices, liquid cooling, comprehensively cover all aspects of data center design including providing multiple methodologies. Everything from the acoustical considerations to fire detection / suppression and even commissioning are covered. Dedicated special publications on aspects such as structural and vibration guidelines and particulate and gaseous contamination, shed a long overdue light on important topics that have pre- viously been given little to no consider- ation by data center designers. To help with the application side, the High Density Data Centers – Case Studies & Best Practices publication presents a collection of innovative high density cooling solutions in operational data centers to help show the industry at large some of what is possible with the correct use of the data being provided. In general, the intent of these publications is not to dictate the design, but to assist data center designers by providing vendor neutral data that empowers and enables them to make informed decisions. Operations Just as thermal guidelines has pro- vided important design information for new data centers, existing data centers also need to reduce energy consump- tion in order to stay competitive. e same thermal guidelines that apply to new data centers can oen be retrofitted to existing data centers. In addition, ASHRAE's Green Tips for Data Centers provides an excellent checklist that can be used by existing operators as they look for the 'low hang- ing fruit' with regard to making their data center more efficient in the most cost-effective manner possible. With the increasing popularity of the PUE metric, clear guidelines for data center operators on how to accu- rately measure your data center energy consumption become more and more important and lead to the Real-Time Energy Consumption Measurements in Data Centers publication, a joint effort between ASHRAE TC9.9 and e Green Grid. is was then followed by a second TC9.9 and e Green Grid joint publication entitled PUETM: A Comprehensive Examination of the Metric. is publication has removed the vagueness behind the correct pro- cedures for calculating, reporting and analyzing the PUE metric, now widely recognized as the de-facto data center energy efficiency comparative unit of measurement. Other ermal Guidelines has also influenced the IT industry to include "ermal Reports" as a part of their product specifications. e ermal Report was introduced and defined in very first edition of ermal Guidelines in reaction to the lack of published heat release information from IT equipment (prior to which designers were either conservatively using the nameplate power rating or basing their loads on an anecdotal percentage of the nameplate). closing comments e data center industry needs to continue to have a source of informa- tion that can continuously draw on experts in the many data center fields. It also needs an agile organization that can publish new information quickly. ASHRAE TC9.9 continues to play a central role in both regards and like the data center industry, remains very ac- tive with multiple publications planned on a variety of hot topics scheduled for release in this year and subsequent ones.
