Abstract
The present invention relates to providing reliable power to a storage device. In one embodiment, the storage device employs dual external power supplies. The power supplies may both provide power to the storage device. Alternatively, the power supplies may provide power in different configurations. One power supply may be a primary supply providing all or a majority of power, while the other power supply may be a backup. The storage device may comprise high efficiency DC-to-DC converters to permit the use of lower power-rated external power supplies. A staggered startup procedure by the storage device may be implemented to manage peak power draw. The storage device may be further configured to load balance and power share between the external power supplies. In addition, the storage device is configured to monitor the status of the external power supplies and send a notification if one or more of the power supplies fails.
