1. Facility Power to Rack PSU / WHIP: 1OU and 2OU When connecting a data center rack to a building's facility power busway or main power feed, customers will often utilize AC power connectors and cable assemblies known as power whips to make this connection to the data center power distribution cabinet (PDC) or direct to rack's power shelf.
Data centers adopted many things from telecoms, most notably the ubiquitous 19-inch rack, which was standardized by AT&T way back in 1922. Now, those racks hold electronic systems whose guts - the chips inside the servers – fundamentally all run on DC power. But data centers distribute power by AC.
Data centers are increasingly adopting 400V DC rack power distribution as an alternative to traditional AC systems, driven by the need for improved efficiency, reliability and cost-effectiveness.
DC Power for Improved Data Center Efficiency: The objectives of this demonstration project are to develop and demonstrate a power delivery system that does not contain as many power conversion stages using existing equipment and vendors where possible. This project implemented a power delivery system that distributes DC to the server racks.
