Single-Phase or Three-Phase Input Power for Rack PDUs

Posted on February 3, 2015 by Greg More

Over the past few years, average power consumption per server has rapidly increased with the adoption of high-power computing equipment like blade servers. The typical power required at a rack has increased from 2 kilowatts to 12 kilowatts and continues upward. In addition, ongoing deployment of densely packed storage, virtualization, and cloud computing results in data centers with greater watts/sq. ft. requirements due to more densely packed racks such as a rack filled with 1U servers. To support new, power-hungry IT equipment, data center managers have to deliver more power to the IT equipment rack.
