Emerson Network Power Introduces SmartAisle(TM) Solution to Improve Effectiveness of Data Center Cooling
Columbus, Ohio - As high heat densities continue to push the limits of data center cooling, Emerson Network Power, a business of Emerson (NYSE: EMR) and the global leader in enabling Business-Critical Continuity(TM), today introduced the SmartAisle cooling management solution that utilizes cold aisle containment to increase cooling efficiency and rack capacity. The SmartAisle solution is available to customers worldwide.
Leveraging the hot aisle/cold aisle rack configuration, the flexible SmartAisle solution contains the cold aisle to prevent hot and cold air from mixing, while adding a layer of intelligent management through the Liebert iCOM(TM) control system. The combination of cold aisle containment and precise aisle-level control of temperature, humidity and airflow allows the SmartAisle solution to deliver greater than 30 percent energy savings and a 25 percent cooling capacity increase without compromising availability.
"Containment has proven to be an effective approach to increasing cooling system efficiency, but containment without control is only a partial solution," said Fred Stack, vice president of marketing for the Liebert Precision Cooling business of Emerson Network Power in North America. "With the SmartAisle solution we've taken containment to the next level, magnifying the results that can be achieved by providing greater control of the contained environment while also enabling a modular approach to data center optimization."
Knurr® cabinets from Emerson Network Power are utilized within the cold-aisle containment structure. The SmartAisle solution can also be adapted to existing IT racks. A clear plexiglass ceiling system serves as a roof to contain cold air. Swinging or sliding doors contain the areas at the ends of the aisle. Horizontal and vertical rack blanking panels are used to optimize the cabinet airflow. An alternative curtain system is available for ceiling containment as an alternative to the plexiglass ceiling panels.
The addition of the Liebert iCOM control system provides monitoring, control and communications vital to the SmartAisle solution's significant performance improvement over standard containment structures. Remote sensors in both the hot and cold aisles allow Liebert iCOM to ensure proper temperature, humidity and airflow to the inlet of the servers. The control system monitors conditions in the cold aisle to independently control both the variable capacity compressor (or chilled-water cooling capacity) and the fan speed of the cooling units and allows the units to work in teamwork mode for energy-efficient load sharing operation.
"While constructing our newest energy efficient, high-density co-location facility in Santa Clara, we evaluated several different energy saving infrastructures for our 30,000-square-foot data center to support over 1,000 high-density cabinets. Our goal was to find a solution that would provide us with efficient cooling, while we gradually expand our customer base," said Tom Wye, president and CEO, Bay Area Internet Solutions. "Carefully comparing the various technologies, we found that the SmartAisle solution from Emerson Network Power would provide us with the most efficient and flexible cooling system available. The SmartAisle solution is now an integral component of our cooling infrastructure."
"Nemertes sees sensor-driven intelligent management of cooling as the most important improvement in data center climate control in many years," said John Burke, a principal research analyst at Nemertes Research. "Fifty-nine percent of the enterprises Nemertes speaks with say that data center HVAC is still a challenge, especially problems with density, efficiency, and control of airflow. Improved, and especially more intelligent, cooling infrastructure is their main strategy for addressing such problems."
The SmartAisle solution can be used on raised or non-raised floors, and is compatible with variable capacity Liebert DS and Liebert CW cooling units containing Liebert iCOM controls, as well as row-based Liebert CRV and Liebert XD systems with Liebert iCOM controls. The system is capable of cooling up to 30kW per rack, depending on whether internal or external cooling is used with the cold aisle containment. Existing IT racks can be retrofitted with a SmartAisle containment system.
