ECC RAID RAID CONTROLLER DEVICE AND STORAGE DEVICE CONFIGURED TO RECOVER DATA HAVING UNCORRECTABLE ECC ERROR

摘要

The present invention provides the storage systems that a kind of RAID controller is configured as the input of management data with output RAID. A kind of RAID controller equipment includes ECC results management devices, uncorrectable error counter and restores calculator. When data block includes that there is ECC cell data uncorrectable ECC error to be distributed and store being read for inventory in multiple data chunks, the management of results management device indicates that multiple ECC cell data elements have uncorrectable ECC error about ECC error correction code resulting indicator. Counter calculates unrecoverable error quantity result indicator and indicates that uncorrectable error correcting code ECC error corresponds to the correction code unit data block having the same for making multiple data in ECC result indicators. When the quantity of calculating is without departing from reference value, restore calculator and restores correction code unit data, with the identical ECC Block cell data for making multiple data there is uncorrectable ECC error to correspondingly rotate in the ECC cell data that this success is read, corresponding rotation is had based on odd even. ;The 2017 of copyright KIPO submissions
