Abstract
A fault tolerant power supply system for providing reliable power to a redundant array of data storage units. The system includes one power supply module for each channel of the array of data storage units. A power supply failure will not impact the ability of the data storage system to recover data due to the ability of the data storage system to reconstruct data in an unavailable channel from the data storage units of each other channel. The use of independent power supplies provides a power supply system which has a power capability equal to the sum of the power requirements of the data storage units, and voltage outputs just sufficient to meet the voltage requirements of the data storage units.
