DETECTING DATA-ACCESS-ELEMENT-SELECTION ERRORS DURING DATA ACCESS IN DATA-STORAGE ARRAYS

摘要

An embodiment of the present disclosure relates to detection of data access element selection errors during data access in data storage arrays. An embodiment of the disclosure describes a system including a data storage array comprising a first and a second error identifier. The error identifiers generate an error signal in case multiple data access elements are selected or no data access element is selected, respectively. A system for detection of data-access-element-selection errors further comprises a common error-signal generator which provides an output when an error signal is generated by either of said error identifiers.
