Redundant power backplane for NAS storage device

摘要

The present invention relates to methods and systems for providing reliable power to a storage device, such as a network attached storage. In one embodiment, the storage device employs a redundant power backplane design using a DC-to-DC converter per drive in the backplane. Each drive is thus provided its own independent power interface to the power backplane. One embodiment may employ DC-to-DC converters having integrated N-channel MOSFETs to provide overcurrent and thermal protection. In addition, an embodiment may employ a staggered startup procedure to manage peak power draw.

主权项

1. A storage device configured with a decentralized power backplane, said storage device comprising:
at least one disk drive; a controller configured to provide at least one power signal from a power supply, and to manage access to the at least one disk drive; and a backplane, interconnecting the controller and the at least one disk drive, the backplane comprising:
a plurality of converters configured to convert the at least one power signal into a set of second power signals for the at least one disk drive; anda plurality of connectors coupled to the plurality of converters, wherein the backplane is separate from the controller, wherein the plurality of connectors are configured to receive the set of second power signals from the plurality of converters, provide the set of second power signals to the at least one disk drive, and communicate data with the at least one disk drive.
