Abstract

A procedure, enabled in software, and applied to a cache/disk environment controlled by a host computer operating through a Block Multiplexor Channel Interface and Storage Control Unit, functions to use FIPS 97 and FIPS 60 protocols to execute data transfers between host processors and a plurality of disks whereby simultaneous operations can function with up to 16 disk units. Up to seen I/O requests can be queued on each of the 16 disk units while the system can normally operate in the cache/disk mode. Additionally, the system can operate in the disk-only mode or storethrough mode.
