The present invention discloses a disk array access management system connected between a host computer and at least two independent concurrently operational disk arrays. Each of these arrayas includes a plurality of disks, the disk access management system includes a central processing unit (CPU) executable extension device directly accessible and executable by a CPU of the host computer. The disk access management system further includes a concurrent disk array interface device for interfacing with the concurrent disk arrays for performing disk accesses from the host computer to the disks. The CPU executable extension device is employed for initializing, configuring and controlling the concurrent disk array interface device in performing the concurrent disk accesses operations under direct control of the CPU. In a preferred embodiment of the disk access management system, the CPU executable extension device includes an array basic input-output system (BIOS) for including a plurality of instruction sets executable by the CPU for performing the disk access operation. The CPU executable extension device further includes a read only memory (ROM) for storing a plurality of configuration and initialization data therein to be employed by the CPU for initializing, configuring and controlling the concurrent disk array interface device in performing the concurrent disk accesses operations.
