Abstract

A data storage system (400) that includes first and second controllers ( 404,408) is provided. Data is mirrored from one controller (404) to the other controller (408) according to different steps depending on the amount of data to be mirrored. When the data to be mirrored is less than or equal to a predetermined number of bytes, one less interrupt is generated than when the data to be mirrored is greater than the predetermined number of bits.
