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.”   …

Consonus deploys internal green technology program to drive efficiency into its data center operations, with impressive results for an existing data center.  …

…   “The 15-year-old facility achieved an impressive PUE rating — a product of energy efficiency efforts implemented by Consonus over the past year. 

The industry average is typically between 2.0 and 2.2; Consonus’ West Data Center PUE score was considerably lower at 1.35. 

The fact that we were able to significantly improve the PUE score of an existing facility debunks a common myth shared by many — that these scores are only achievable in new facilities, said Daniel Milburn, senior vice president and chief operating officer of hosting and infrastructure services for Consonus. “   …

EPA Energy Star Label for Data Centers requires top quartile efficiency performance

Posted in data-center-energy-star, energy-efficiency, energy-star-compliance, epa, power-savings, power-usage, power-usage-effectiveness-rating, pue on June 8th, 2010 by FrankM – Comments Off

The U.S. Environmental Protection Agency has made the Energy Star label attainable for stand-alone data centers and buildings that house large data centers.  To achieve the Energy Star rating, data centers must achieve the top quartile (25 percent of their peers) of energy efficiency using the EPA energy performance scale. Data center energy efficiency will translate into financial savings and a smaller carbon footprint.  …

…   “EPA uses a commonly accepted measure for energy efficiency, the Power Usage Effectiveness metric, to determine whether a data center qualifies for the Energy Star label. Before being awarded the Energy Star, a licensed professional must independently verify the energy performance of these buildings and sign and seal the application document that is sent to EPA for review and approval.

Data centers are found in nearly every sector of the economy and deliver vital information technology services, including data storage, communications and internet accessibility.

Data centers use a significant amount of energy, accounting for 1.5 percent of total U.S. electricity consumption at a cost of $4.5 billion annually, an amount that is expected to almost double over the next five years.

Significant energy and cost savings are possible through modest gains in efficiency. The energy consumed by data centers is growing every year. “   …
