Computer-readable recording medium having stored therein information processing program, information processing method, and information processing apparatus

A computer-implemented information processing method comprising:

• 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 a plurality of second physical storage devices including the first physical storage device is accessed from the one or more first virtual 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 plurality of second index values being obtained by summing the calculated plurality of first index values for each virtual machine associated with each of the one or more first virtual storage devices, wherein the calculating of the plurality of first index values includes:
• obtaining a third index value indicating an access load for each command from each of the one or more virtual machines to the one or more first virtual storage devices;
• and
• calculating the plurality of first index values, based on information for each of the one or more first virtual storage devices indicating a ratio of an access load according to information indicating a redundancy configuration of the plurality of second physical storage devices, and based on the third index value.

An information processing apparatus comprising:

• a memory;
• and
• a processor coupled to the memory, the processor being configured to execute a process comprising:
• 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 a plurality of second physical storage devices including the first physical storage device is accessed from the one or more first virtual 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 plurality of second index values being obtained by summing the calculated plurality of first index values for each virtual machine associated with each of the one or more first virtual storage devices, wherein the calculating of the plurality of first index values includes:
• obtaining a third index value indicating an access load for each command from each of the one or more virtual machines to the one or more first virtual storage devices;
• and
• calculating the plurality of first index values, based on information for each of the one or more first virtual storage devices indicating a ratio of an access load according to information indicating a redundancy configuration of the plurality of second physical storage devices, and based on the third index value.
