Abstract
A data storage system includes a disk drive array including a plurality of disk drives; a first storage processor for controlling the operation of the data storage system; a second storage processor for controlling the operation of the data storage system; a first arbiter for controlling communication of data from the first storage processor and the second storage processor to a first group of disk drives of the disk drive array; and a second arbiter for controlling communication of data from the first storage processor and the second storage processor to a second group of disk drives of the disk drive array. Selected data is redundantly stored on disk drives in the first group of disk drives and the second group of disk drives, such that, upon failure of the first arbiter, the selected data is available to the first storage processor and the second storage processor through the second arbiter.
