  • Method and apparatus for ensuring data integrity in redundant mass storage systems
    Patent number: 7698591
    Abstract: A method for maintaining integrity of data in a redundant mass storage system is provided that includes selecting a plurality of scrubbing selections for a memory system in which each of the scrubbing selections selects a data section on the memory system. The method also includes selecting a respective scrubbing implementation for each scrubbing selection in which each of the scrubbing implementations determines a data check. Another exemplary method is provided for ensuring integrity of data stored in a redundant mass storage system. An apparatus is provided for maintaining data integrity in a redundant mass storage system. A computer-readable storage medium containing a set of instructions for a general purpose computer is provided. The set of instructions include a method for ensuring data integrity in a redundant mass storage system.
