摘要： A method includes calculating a plurality of first index values indicating access loads from one or more first virtual storage devices accessing a first physical storage device of a plurality of physical storage devices, to the first physical storage device, in a case where access loads from the one or more first virtual storage devices to a plurality of second physical storage devices including the first physical storage device are equalized across the second physical storage devices, the plurality of second physical storage devices being associated with the one or more first virtual storage devices; and outputting a plurality of second index values indicating access loads from a plurality of virtual machines to the first physical storage device, the second index values being obtained by summing the calculated first index values for each virtual machine associated with each of the one or more first virtual storage devices.
