Input and output control program, information processing apparatus, and input and output control method

摘要

PROBLEM TO BE SOLVED: To appropriately control input/output quantity.SOLUTION: An information processor is configured to measure the number of input/output to a disk and a mean time spent on the execution of input/output to the disk for every customer, to calculate a total time spent on the number of input/output from the total of the counted number of input/output and the total of the measured mean time spent on the execution of input/output for every customer, to calculate the maximum number of input/output per unit time processable by the disk from the total of the total time spent on the number of input/output calculated for every customer and the total of the number of input/output counted for every customer, to calculate the maximum number of input/output per unit time allowable as input/output to the disk for every customer from the maximum number of input/output of the disk and the maximum load to the disk preliminarily set for every customer, and to control input/output to the disk for every customer based on the maximum number of input/output calculated for every customer.
