How to increase the degree of fault-tolerant array of storage units and data storage systems

摘要

invention dosing technologies (dodging technique) as described referring to the use of an array of m storage units provides a method and system for increasing the acceptable error level. the k stripes are stored across the array of storage units, each stripe is the minimum Hamming distance d = r + 1 has n + r elements that correspond to a symmetric code having a. Each element of a stripe is stored on a different storage unit. More than one element is selected when the difference between the minimum distance of at least two streets and the recipient stripe (recipient stripe) contributors stripes (donor stripe). These elements are rebuilt on a storage unit that does not have any element of the recipient stripe. Therefore, the missing element of the recipient stripe is rebuilt on the selected element.
