Today NetApp (NTAP) is opening the doors to its new energy-efficient data center at its campus in Research Triangle Park (RTP), North Carolina. The new facility will enable NetApp to consolidate its engineering facilities into a global dynamic lab (GDL) and will house NetApp's IT operations.
The 132,000 square foot facility houses a 36,000 square foot data center supporting 2,166 racks of IT equipment with a designed power load of nearly 25 megawatts.
Estimated PUE of 1.2
The NetApp data center was designed with numerous features to reduce the energy needed to power and cool those servers, which the company estimates will result in a Power Usage Effectiveness (PUE) rating of 1.2.
The PUE metric (PDF) compares a facility’s total power usage to the amount of power used by the IT equipment, revealing how much is lost in distribution and conversion. A rating of 1.2 would place the NetApp facility among the most efficient data centers in the world, in roughly the same class as facilities operated by Google and Microsoft.
NetApp estimates that its focus on energy efficiency will generate savings of $7.3 million a year on the company's power bill and reduce its CO2 output by 93,000 tons a year - the equivalent of removing 15,400 cars from the road.
The energy effiency features at the RTP data center include:
- Running Warmer: NetApp says its average supply air temperature will be 74 degrees, slightly higher than the 68 to 72 degree range seen in many data centers.
- Airside Economization: The data center will be cooled using just outside air (free cooling) for an estimated 67 percent of the year.
- Pressure Control: Modulating fans, based on NetApp's proprietary technology, supply pressure-controlled rooms and regulate the volume of air to avoid oversupplying air and wasting energy.
- Cold aisle containment: The cold and hot air aisles are isolated to protect supply air temperatures from being affected by hot air returning from the racks.
- Overhead air distribution: Instead of pumping cold air up through a raised floors, overhead air distribution takes advantage of cold/hot air buoyancy and eliminates ductwork and energy needed to power fans.
NetApp said its software will help improve data management and storage efficiency in the data center. The company will use virtualization to build a private cloud environment to provide virtual access for NetApp engineering labs around the world.
