As organizations pursue improvements in reliability and energy efficiency, power design in data centers gets substantial attention—particularly from facilities and engineering personnel. At the same time, however, many IT professionals tend to spend little time or energy on the specific products they use to deliver and distribute electrical power. In?rack power is often considered less strategically important than which servers or databases to deploy, and it is often one of the last decisions to be made in the overall design of the data center. But choosing the right in-rack power solutions can save organizations from potentially crippling downtime and deliver significant up-front and ongoing savings through improved IT efficiency and data center infrastructure management.
One of the basic decisions in data center design is which rack power distribution units (PDUs) to use and where to use them. The rack PDU is a fundamental building block of any data center, transforming high-capacity raw power feeds to lower-capacity outlets for rack servers, blade chassis, network switches, storage systems and a myriad of hardware technologies that comprise today’s highly diverse and power-hungry MDFs (main distribution frames) and data centers. PDUs come in a variety of flavors, offering varying functionality at varying price points. Paying closer attention to which ones you are using and how you are using
them can pay off in a big way.
