Efficient Application of Disk Storage to the DRCS Data Migration Scheme.

摘要

A data migration scheme has been in operation on the DRCS Central Computer for approximately two years. During this period, tens of thousands of datasets have been migrated to magnetic tape to make the best use of disk storage space. The number of dataset retrievals, although still well within the processing capabilities of the IBM 370 computer system, has predictably grown. This report describes an innovation designed to lessen the impact of retrieval requests on the system resources, especially in the operator intensive area of tape handling. (Author)
