DEVICE AND METHOD FOR CARRYING OUT PERFORMANCE BALANCE EVALUATION AND SIZING OF COMPONENT OF COMPUTER SYSTEM

摘要

PPROBLEM TO BE SOLVED: To find/improve a component with excessive specifications or putting a limit on performance of an existing computer system. PSOLUTION: A performance evaluation index acquiring means 4 is provided for acquiring transaction density and a performance evaluation index of each device 7-10 by individually sending and receiving test applications to each device 7-10 composing the evaluation target computer system and changing the number of test applications. A utilization factor acquiring means 3 is provided for acquiring a utilization factor of each device 7-10 by sending a test application to the evaluation target computer system and having each device 7-10 carry out processing like a normal service operation. A tolerance calculating means 5 is provided for calculating tolerance of each device 7-10 by dividing the performance evaluation index of each device 7-10 by their respective utilization factors. A performance balance evaluating means 6 is provided for determining one of the devices 7-10 as a reference device and calculating performance balance from a ratio of tolerance of a device with respect to tolerance of the reference device.
