Effects of secondary storage I/O contention on the performance of an interactive information management system

Abstract	An analysis is presented of the effects of contention for the use of the Input/Output channel to secondary storage. Quantitative results are obtained by means of a discrete simulation for an IBM System/360 Model 50 computer under the operating environment of a real-time interactive management information system (United Aircraft Information Management System - UAIMS). Alternative software and Input/Output hardware device configurations that would support increased demands for service are modeled and the relative throughput capabilities and device utilizations are compared and discussed. The model, written in GPSS/360, was designed to give substantive results reasonably independent of the specific software packages involved. In this way performance aspects dependent on the basic system architecture become more readily apparent. Conclusions drawn from the statistics of the model runs are general to interactive on-line systems of the nature discussed. Results are derived in relative rather than absolute terms. A representative benchmark configuration was modeled, and the capabilities of the other configurations measured in terms of this. When two on-line transaction partitions are maintained, it is shown that the through-put capability can be improved by 16 to 42 percent by the use of two selector channels instead of one. The degree of improved capability is dependent on the device type attached and the amount of contention that exists for the seek facility.
