Telus green data center planned for Rimouski Quebec

Posted in certification, country-canada, data-center-design, green-design, green-power, low-power, telus on May 18th, 2011 by FrankM – Comments Off

Telus is investing $65 million into a Tier III Intelligent Internet Data Centre in Rimouski, Quebec.  The facility will integrate green design to achieve LEED (Leadership in Energy and Environmental Design) Gold certification.

Skanska will build the green data center with a target rating Power Usage Effectiveness, or PUE,  of 1.15.  …

…   “Rimouski is an ideal location for TELUS’ Intelligent Internet Data Centre because of the city’s highly skilled and dynamic workforce. By choosing to build the facility in Rimouski, TELUS can also benefit from one of Quebec’s unique advantages, its hydroelectric power — an abundant source of green energy.

Rimouski’s moderate climate also contributes to lower energy requirements for the building’s cooling and heating systems. Furthermore, locating the facility more than 250 kilometres from large city centres offers TELUS’ business clients the benefits of greater geographic diversity and improved business continuity.”   …

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.”   …

Recommendations.

Facebook Open Compute Project Hacks Infrastructure for Energy Efficiency

Posted in data-center, data-center-design, data-center-efficiency-program, facebook, green-data-center, green-design, green-power, reduce-power-consumption on April 8th, 2011 by FrankM – Comments Off

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.”   …

IBM uses SPECint to benchmark system energy efficiency

Posted in ibm, low-power on March 28th, 2011 by FrankM – Comments Off

How should systems energy efficiency be compared?  IBM uses the Standard Performance Evaluation Corporation‘s SPECint rate 2006 measure in performance per watt, which is calculated by dividing the performance from the tables on the Dare to Compare Performance webpage by the recommended maximum power usage for site planning.  …

…   “As this data below shows, using the SPECint_Rate2006 benchmark from SPEC.org, Power Systems are more energy efficient than the HP and Sun systems at each system level. The comparisons for the POWER7 processor based systems are particularly impressive.”   …

Dell Compellent storage efficiency improves energy use

Posted in dell, reduce-power-consumption on March 14th, 2011 by FrankM – Comments Off

UK university deploys new storage technology to meets its growth requirements with efficient energy use and reduced footprint requirements.  …

…   “Fluid Data also is helping the university meet its environmental goals, reducing campus energy use and the university’s carbon footprint.

Each of the Dell Compellent SANs delivers twice the capacity, and performance is also doubled, yet the Fluid Data storage consumes the same amount of power as the legacy SANs, making them twice as energy-efficient.

The university also has reduced its hardware footprint by more than 60 percent.

Specifically, for each SAN, capacity has expanded from 23TB to 50TB, performance has doubled from 10,000 IOPS (input-outputs per second) to 20,000 IOPs, and the university’s storage footprint has decreased from 84 to 30 rack units.”   …
