Abstract
Erasure-encoded data is stored across a plurality of storage devices in a data storage system. The erasure-encoded data includes k data elements to store on k data storage devices and m parity elements to store on m parity storage devices, wherein for a given minimum Hamming distance d of the data storage system and m≧(d−1), data elements are assigned only to corresponding unique combinations of parity elements of size (d−1).
