Abstract
A large mainframe computing environment consists of three major hardware components: the mainframe computer, the input/output (I/O) subsystem, and the telecommunication network. Because the cost of each of these components can range from one to ten million dollars, care must be taken when configuring each component to maximize resource utilization while minimizing costs. The task is most difficult for the I/O subsystem. The I/O subsystem is comprised of a series of hardware devices that access data stored on magnetic media. This data is transferred to the computer's main memory for use by computer software. These hardware devices are produced in different models with different costs and varying degrees of performance. Measuring I/O subsystem performance by physically altering the hardware devices is cost prohibitive. This paper presents a methodology to simulate an I/O subsystem and to measure and analyze the different combinations of hardware devices.
