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

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.
