A power distribution unit (PDU) is a device designed to distribute electric power to servers, networking hardware, telecom equipment, and other devices located within a data center. It does not generate or condition power, but delivers AC power from an uninterruptible power supply (UPS), a generator, or utility power source.
Traditional data center power distribution designs consist of multiple PDUs delivering power to remote power panels (RPPs) throughout the building, which in turn deliver power to network hardware racks via power cabling routed underneath a raised floor called “whips”.
