Improving Performance of an IBM 360/67 Computer by Using a Hardware Monitor on the Disk Facility

Abstract

The provision of comprehensive services by a complex modern computer installation is expensive. In the face of increasing demand for computer service, system expansion may be proposed. This expansion may not be necessary if existing resource utilization can be increased or more equally distributed. The report investigates the possibility of increased IBM 360/67 system throughput through a balancing of the demand on the individual modules of an IBM 2314 Disk Facility. The performance of the disk modules is measured utilizing a hardware monitor. The hardware monitor is also used to obtain system performance profiles which are plotted by a FORTRAN program. Comparison of system throughput is made during times when different sets of resources are available. Recommendations are made to improve system performance by rearranging the data sets on the disk modules.
