Patent attributes
A data center includes one or more racks, computing devices mounted in the racks, and an electrical power system. The electrical power system supplies power to the computing devices in the racks. The electrical power system includes one or more rack power distribution units (PDUs) and one or more floor power distribution units (PDUs) or power panels. The rack PDUs include rack-level circuit protection devices that protect the computing devices receiving power from the rack PDU from overcurrent conditions. The floor PDUs or power panels include floor-level circuit protection devices that protect the computing devices from overcurrent conditions. The rack-level circuit protection devices have a faster response time than the floor-level circuit protection devices.
