Updated metrics for datacenter efficiency measurements

Posted in data-center-efficiency-program, green-grid, green-power, low-power, metrics, pue, servers on May 17th, 2011 by FrankM – Comments Off

The Green Grid has posted updated guidelines for applying its PUE, or Power Usage Effectiveness, metric.  The update includes specific recommendations for how to measure and calculate PUE in mixed-use data center facilities and introduces a condenser water source energy weighting factor.

Enhanced principles are introduced into the measurement definitions:

…   “When calculating PUE, IT energy consumption should, at a minimum, be measured at the output of the uninterruptible power supply (UPS). However, the industry will continue to improve measurement capabilities so that measurement of IT energy consumption directly at the IT load (e.g., servers, storage, network, etc.) becomes the common practice.”   …

Facebook’s Prineville data center has reduced its energy consumption by 38 percent and delivers the same work as the company’s existing facilities.

Facebook is sharing its achievements through the Open Compute Project to collaborate with the technology industry on sustainable practices in the green data center.  …

…   “As a first step, we are publishing specifications and mechanical designs for the hardware used in our data center, including motherboards, power supply, server chassis, server rack, and battery cabinets.

In addition, we’re sharing our data center electrical and mechanical construction specifications.

This technology enabled the Prineville data center to achieve an initial power usage effectiveness (PUE) ratio of 1.07, compared with an average of 1.5 for our existing facilities.”   …

Energy efficiency in data centers

can be enabled through adoption of standard definitions for productivity.  Labels such as EnergyStar can be susceptible to eligibility-creep, which results undifferentiated products.  …

…   “It is difficult to define energy efficiency for a complex system such as a data center or a server. Energy efficient is usually defined based on the delivery of the same or better service output with less energy input, but for servers and data centers service output is difficult to measure and varies among applications. Data center operators need standard definitions of productivity in order to purchase energy-efficient equipment, operate it in an optimal way, and design and operate the buildings to house it. “   …

Data Center ASHRAE Prescriptive Cooling System Energy Efficiency

Posted in air-economizers, ambient-air-cooling, ashrae, cooling-system, data-center-efficiency-program, economizer, energy-efficiency, google, standards on April 13th, 2010 by FrankM – Comments Off

Google and its industry peers react to ASHRAE cooling standard for data centers. …

… “Unfortunately, the proposed ASHRAE standard is far too prescriptive. Instead of setting a required level of efficiency for the cooling system as a whole, the standard dictates which types of cooling methods must be used. For example, the standard requires data centers to use economizers — systems that use ambient air for cooling. In many cases, economizers are a great way to cool a data center (in fact, many of our companies’ data centers use them extensively), but simply requiring their use doesn’t guarantee an efficient system, and they may not be the best choice. Future cooling methods may achieve the same or better results without the use of economizers altogether. An efficiency standard should not prohibit such innovation. ” …
