APPARATUS, SYSTEM, AND METHOD TO INCREASE DATA INTEGRITY IN A REDUNDANT STORAGE SYSTEM
摘要:
An apparatus, system, and method are disclosed to increase data integrity in a redundant storage system. The receive module receives a read request to read data from a logical page spanning an array of N+P number of storage elements. The array of storage elements includes N number of the storage elements each storing a portion of an ECC chunk and P number of the storage elements storing parity data. The data read module reads data from at least a portion of a physical page on each of X number of storage elements of the N+P number of storage elements where X equals N. The regeneration module regenerates missing data. The ECC module determines if the read data and any regenerated missing data includes an error. The read data combined with any regenerated missing data includes the ECC chunk.
