New Book Provides Comprehensive Examination of the Power Usage Effectiveness Metric for Data Centers

PORTLAND, Ore., Jan. 21, 2014 /PRNewswire-iReach/ -- The Green Grid® Association, the industry's leading voice for advancing data center and IT resource efficiency, together with ASHRAE, a global building society, have collaborated to create and publish a new resource on Power Usage Effectiveness (PUE), titled PUE: A Comprehensive Examination of the Metric.


"Data centers are complex systems for which power and cooling remain key issues facing IT organizations today. The Green Grid Association's PUE metric has been instrumental in helping data center owners and operators better understand and improve the energy efficiency of their existing data centers, as well as helping them make better decisions on new data center deployments," said John Tuccillo, chairman of the board for The Green Grid Association and ‎vice president of Global Industry and Government Alliances at Schneider Electric.

PUE measures the relationship between the total facility energy consumed and the IT equipment energy consumed. When viewed in the proper context, PUE provides strong guidance for and useful insight into the design of efficient power and cooling architectures, the deployment of equipment within those architectures, and the day-to-day operation of that equipment. Since its original publication in 2007, the metric has been globally adopted and The Green Grid has continued to refine the metric's measurement methodology with collaborative industry feedback.

PUE: A Comprehensive Examination of the Metric consolidates all previously published material related to PUE and includes some new material. Whether a novice or expert in the IT industry, a CIO or facility planner, ITE manufacturer or energy auditor, the book is an essential guide for all who implement, report on and make decisions based on data center energy use metrics.

For sale through ASHRAE's web site and at conferences, the new book provides a high level description of the concepts surrounding PUE, plus in-depth application knowledge and resources to those implementing, reporting, and analyzing data center metrics. It also includes detailed information on procedures for calculating, reporting and analyzing PUE measurements, plus quick references to other resources in print and online.

The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data...
Cloud computing is unquestionably one of the driving forces of DevOps, as the automation of operations transforms enterprise software development. DevOps, however, is more than a technology trend, as it represents a move toward silo-busting, self-organizing horizontal teams that drive business velocity. At the same time, enterprise Digital Transformation represents an upheaval across the enterprise, as customer preferences and behavior drive enterprise technology decisions. This transformation ...
Most of the IoT Gateway scenarios involve collecting data from machines/processing and pushing data upstream to cloud for further analytics. The gateway hardware varies from Raspberry Pi to Industrial PCs. The document states the process of allowing deploying polyglot data pipelining software with the clear notion of supporting immutability. In his session at @ThingsExpo, Shashank Jain, a development architect for SAP Labs, discussed the objective, which is to automate the IoT deployment proces...
Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.
DevOps is about increasing efficiency, but nothing is more inefficient than building the same application twice. However, this is a routine occurrence with enterprise applications that need both a rich desktop web interface and strong mobile support. With recent technological advances from Isomorphic Software and others, rich desktop and tuned mobile experiences can now be created with a single codebase – without compromising functionality, performance or usability. In his session at DevOps Su...
In demand-intensive mobile and web applications, an emerging pattern is to host the Systems of Engagement in the cloud (for maximum responsiveness) but keep the Systems of Record with the other important business systems in the company datacenter, often on a tightly secured mainframe.
