PROTECTING DATA INTEGRITY IN DE-DUPLICATED STORAGE ENVIRONMENTS IN COMBINATION WITH SOFTWARE DEFINED NATIVE RAID

摘要

A mechanism is provided in a data processing system for securing data integrity in de-duplicated storage environments in combination with software defined native redundant array of independent disks (RAID). The mechanism receives a data portion to write to storage, divides the data portion into a plurality of chunks, and identifies a given chunk within the plurality of chunks for de-duplication. The mechanism increment a de-duplication counter for the given chunk and determines a RAID level for the given chunk based on a value of the de-duplication counter. The mechanism stores the given chunk based on the determined RAID level.

1. A method, in a data processing system, for securing data integrity in de-duplicated storage environments in combination with software defined native redundant array of independent disks (RAID), the method comprising:
receiving a data portion to write to storage; dividing the data portion into a plurality of chunks; identifying a given chunk within the plurality of chunks for de-duplication; incrementing a de-duplication counter for the given chunk; determining a RAID level for the given chunk based on a value of the de-duplication counter; and storing the given chunk based on the determined RAID level.
