Midlands Data Center
Located in Omaha, Nebraska, Cosentry?s Midlands Data Center opened in January 2010 to support the global demand for high performance data centers. Midlands was designed to withstand the region?s harshest weather conditions while delivering unmatched reliability in power, cooling, and connectivity at a low cost. Design specifications included an uptime of 99.9999 percent and efficiency ratings 50 percent greater than traditional data centers. The initial ENERGY STAR energy performance score helped to earn ENERGY STAR certification for the facility, but the score was only considered a starting point. Six months later, Midlands Data Center has already improved its ENERGY STAR score by 6 points, and expectations for the score continue to improve.
Cosentry Midlands Data Center achieves world class efficiency through design and best practices. Midlands is designed to leverage the temperate climate of the North Central U.S. for three season ?free? cooling. In addition, each of the data center suites is 20 feet long, deck to deck, which facilitates an optimal design for efficient air movement within each suite. The design includes; three-foot-long raised floor, hot aisle/cold aisle containment, 12-foot-long floor tile to ceiling tile space, and five-foot-long return air plenums. Computer room air handlers (CRAHs) are installed in separate rooms with return air extensions to plenum. The CRAHs are installed in separate rooms to isolate water piping from computer room raised floor areas. A 100 percent blanking panel policy as well as sealing all floor penetrations assures air recirculation and bypass air flow are not present in the data center. All motors including CRAHs and air handler units (AHUs) are equipped with variable frequency drives (VFDs), the VFDs allow for motors to ramp up and down as needed to save energy use.
Data center energy audits are conducted quarterly to assure optimal efficiency of the data center. Some of the audits include: power systems meter calibrating, raised floor static pressure testing, air quality sampling, cold aisle vent tile CFM sampling, infrared temperature sampling of the data suite, calibrating temperature sensors, efficiency testing of the chillers, and temperature sampling of all critical power equipment.
WCTI water softeners allow Cosentry to effectively condition cooling tower water without the use of chemicals and achieving a 30 percent water savings, while measuring a less than one percent blow down. Irrigation metering has been installed to verify that irrigation is used only when necessary. Water savings are further improved by installing dual flush valves at all water closets.
Advanced monitoring of all power and cooling equipment gives operators a real-time look into the data center efficiencies. Trends are examined on a daily basis to verify that all equipment is performing as efficiently as possible.
Energy reduction is supported and encouraged by executive management, and all Cosentry data centers have invested in energy-saving practices.
