Limiting the effects of faults in a data center
First Claim
1. A data center, comprising:
- one or more racks;
two or more computing devices mounted in at least one of the racks; and
an electrical power system configured to supply power to at least some of the computing devices in the rack, the electrical power system comprising;
one or more rack power distribution units (PDUs) in at least one of the racks, wherein at least one of the rack PDUs is configured to distribute electrical power to at least part of the computing devices in at least one of the racks; and
one or more floor power distribution units (PDUs) or power panels configured to distribute power to at least one of the rack PDUs,wherein at least one of the rack PDUs comprises one or more rack-level circuit protection devices configured to protect at least two of the computing devices receiving power from the rack PDU from overcurrent conditions,wherein at least one of the floor PDUs or power panels comprises a floor-level circuit protection device configured to protect the at least two computing devices from overcurrent conditions,wherein at least one of the rack-level circuit protection devices is configured to have a faster response time than the floor-level circuit protection device.

Abstract
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.
