Document Type and Number:
Japanese Patent JP4307777
Kind Code:
B2
Abstract:
A system, method, and apparatus are disclosed for storing segmented data and corresponding parity data with modules configured to functionally execute the necessary steps of storing segmented data and corresponding parity data. These modules, in the described embodiments, include a designation module that designates a first set of data, from parity data and a plurality of segmented data, as surplus data and designates the remaining data as primary data. A storage module stores the primary data in main electronic storage devices in a distributed manner and stores a first copy of the surplus data on a first main electronic storage device and a second copy of the surplus data on a second main electronic storage device. An optional auxiliary storage module selectively activates an auxiliary electronic storage device and stores the surplus data on the auxiliary storage device. Beneficially, selective activation of the auxiliary electronic storage conserves power.
