National Data Center Service Provider, CoreLink Data Centers, Further Enhances Green Data Center Initiative

MT. PROSPECT, Ill., April 21, 2011 /PRNewswire/ -- National data center service provider, CoreLink Data Centers, LLC  (http://www.corelink.com) today announced specifics of its ongoing green data center initiative, designed to improve efficiencies, minimize carbon footprints and lower operating costs at its Chicago, Las Vegas, Phoenix and Seattle facilities with the installation and implementation of specially designed cooling, electrical, lighting and power distribution systems.

CoreLink's expanded green data center initiative reflects the company's dedicated approach by which it views each of its five data centers as individual ecosystems.  Through the use of Energy Star-rated and otherwise highly efficient devices, CoreLink can contribute strongly to the nation's energy consumption solution. The company's efforts also include strongly encouraging that its managed services and data center hosting clients likewise use 80 percent efficient or Energy Star rated devices.

"As power costs escalate, it's more important than ever to reduce consumption while improving efficiencies," said Loren Zweig, CoreLink VP of Engineering. "As carbon reduction initiatives continue to become more closely aligned with tax rates and reductions, each party in the data center ecosystem has a vested interest in, and responsibility for, ensuring that each device and component is as efficient as possible.

"In addition to cost savings, going green is also simply the right thing to do for our environment and to help control costs for our customers," Zweig said.

CoreLink's enhanced 10-point green data center initiative addresses such geographic and individual data center-related elements and characteristics as local climate, electrical device operating conditions, and temperature control within varying building areas or zones.

For example, the company is finalizing a design for a "free cooling" system for data centers located in its colder weather cities of Chicago and Seattle. Simply put, this system uses filtered outside air for data center cooling that is supplemented with evaporative and mechanical cooling for extreme temperature and humidity conditions. Similarly, in the less humid climates of Las Vegas and Phoenix, CoreLink is investigating evaporative cooling options prior to mechanical cooling to minimize electrical power consumption. Evaporative cooling uses only 10 percent of the power of traditional electrical systems, resulting in a potential Power Usage Effectiveness (PUE) of approximately 1.4 at these facilities.

The other nine elements of CoreLink's enhanced green data center initiative include the installation and implementation of:

• High efficiency uninterruptible power supplies (UPS) which, instead of using utility-based "street" power later conditioned to fit a specific voltage or frequency curve, are Energy Star-rated systems yielding efficiencies of greater than 95 percent at a partial load. High efficiency at a partial load dramatically minimizes UPS-related power consumption, traditionally the largest power consumer in a data center environment.
• Cold and hot aisle containment of hot air removed from servers and cold air supplied to them for increased efficiency and reduced power consumption. By segregating and containing airflow through the use Computational Fluid Dynamics (CFD) computer simulations, CoreLink will optimize containment options while minimizing cooling system power consumption.
• LED lighting project launched to retrofit current data center lighting with LED lights, resulting in an overall 80 percent reduction in the company's data center lighting power consumption.
• White, Energy Star-rated EPDM roofs that reflect rather than absorb solar heat, lessening the amount of required cooling.
• 400/230 Volt electrical distribution systems, in place of standard U.S. 480/208 Volt systems, for greater efficiency and less power lost to heat.
• Electrically Commutated (EC), or "plug" fans that provide greater efficiency than traditional AC motor and belt-driven fans through the use of direct drive motors placed beneath a raised floor, thereby reducing friction resulting from airflow pushed into the floor.
• Variable Frequency Drives (VFDs), devices that regulate pumps and blowers to operate not on constant, but rather at variable speeds depending on conditions resulting in peak efficiency and lower power usage.
• High efficiency HVAC for non-critical data center areas, such as electrical and mechanical areas, without the energy wasting re-heating and humidification elements unneeded in these environments. CoreLink is instead installing highly efficient fan-coil cooling equipment in these spaces.
• Centralized humidification systems installed outside of Computer Room Air Conditioning (CRAC) units for lower aggregate power usage as compared to traditional methods.

"These represent the latest in our ongoing efforts to continually improve data center efficiencies for the environment while improving our critical system resilency for our customers," Zweig said, referring to CoreLink's hallmark flexible and scalable services, continuous expert help and full transparency from each of its five facilities.

CoreLink's rock solid services are backed with a 100 percent Uptime Service Level Agreement (SLA) guarantee covering all infrastructure elements and service metrics including power, temperature and network availability.
