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.”   …


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.”   …

Brocade Custom In-Row Cooling System Enables Green Data Center

Posted in air-economizers, brocade, cooling-system, data-center-design, education, green-data-center, green-design, green-power, low-power on September 14th, 2010 by FrankM – Comments Off

Custom Mechanical Systems and Critchfield Mechanical collaborate to create advanced in-row cooling technology installation for Brocade’s green data center in San Jose.  …

…   “The Brocade San Jose-based data center incorporates technology from CMS and CMI that provides a cutting-edge in-row cooling system with water-side economizer to minimize fan usage and maximize efficiency, saving half a megawatt of energy at full build-out. 

The custom cooling system from CMS and CMI has played a key role in the Brocade data center, featuring fan efficiencies superior to all other cooling options available on the market today.  

Brocade’s data center and its use of custom in-row cooling units, coupled with a highly efficient chilled water plant inclusive of a water-side economizer, provides a mechanical system with a power usage effectiveness (PUE) of less than 1.3. 

Data centers of this size typically have a PUE of greater than 1.5. 

To ensure a fully-customizable and flexible product, multiple iterations of the design were produced in order to meet Brocade’s specifications; 

CMS also worked with the construction team to design features that will simplify maintenance and improve reliability. 

These features include:

  • variable speed ECM motors, 
  • fan redundancy, and a 
  • low-cost maintenance design. ”   …
