Abstract

The system includes one or more host processor interfaces including controllers 12 connected to a main high speed "cache" memory 22 and to disk store interfaces 16 including local controllers, and a supervisory control processor 24. The system responds to requests by the host computer to store and to retrieve information in the format of a conventional tape drive assembly. The data, however, is actually stored or retrieved in piecemeal form from a plurality of disk storage drives 20a to 20n so that the data management system functionally mimics a tape drive and accepts and produces data in serial (tape) format, but in fact stores the data in available spaces in disk units. Data passes in each direction through a main memory 22 under the control of a processor 24 which allocates blocks of a "tape" file to the disk drives. Interfaces 12a to 12n between the computer 10 and memory 22 can contain data buffers and interface between serial format on the computer side and parallel format on the memory side. Interfaces 16a to 16n between the disk drives 20 and memory 22 can also contain data buffers and interface between serial format on the disk drive side and parallel format on the memory side. <IMAGE>
