Data storage array device and data access method

摘要

A data storage array device includes redundant data storage devices and a controller. The controller includes a set of instructions issued to the data storage devices; a detector for detecting responses to the set of instructions; a timer; and a processor for monitoring the responses. If the responses from all data storage devices finished within a period set by the timer, the processor completes response processing for the set of instructions at the point when the responses finished. If the responses from all data storage devices are not finished at the end of a period set by the timer, the processor completes response processing for the set of instructions using only the responses that are finished at the end of the period of the timer.
