A storage module device-data link processor provides for management of data transfer operations between a main host computer system and up to eight separate disk drive units. The data link processor provides a peripheral interface circuit unit (for selection of a given disk drive unit) and which is connected to a formatter circuit unit and a host adapter access circuit unit. The formatter unit establishes the required protocol format for addressing and accessing a particular cylinder, a particular head track and a particular sector within the selected disk drive unit. The host access unit connects the data link processor to the main host computer while also managing execution of the data transfer operations, including error correction and integrity checking.
