Storage control device and storage control method

A storage control method performed by a storage control device that controls access to a first storage device of a plurality of storage devices, the storage control method comprising:

• acquiring, by the storage control device, measurement values of
• plural types of processing index values each indicating a state of processing loads on the storage control device, and
• plural types of access index values each indicating a state of loads of an access process performed for each of a plural pieces of data stored in the first storage device;
• selecting a first access index value corresponding to a first processing index value when the acquired measurement value of the first processing index value exceeds a threshold value set for the first processing index value, the first processing index value being one of the plural types of processing index values, the first access index value being one of the plural types of access index values;
• and
• moving a first piece of data from the first storage device to a second storage device of the plurality of storage devices, access to the second storage device being controlled by a first control device different from the storage control device, the acquired measurement value of the first access index value for the first piece of data being higher than the acquired measurement value of the first access index value for any other piece of data stored in the first storage device.

A computer-readable recording medium having stored therein a storage control program for causing a computer that controls access to a first storage device of a plurality of storage devices to execute a process, the process comprising:

• acquiring measurement values of
• plural types of processing index values each indicating a state of processing loads on the computer, and
• plural types of access index values each indicating a state of loads of an access process performed for each of a plural pieces of data stored in the first storage device;
• selecting a first access index value corresponding to a first processing index value when the acquired measurement value of the first processing index value exceeds a threshold value set for the first processing index value, the first processing index value being one of the plural types of processing index values, the first access index value being one of the plural types of access index values;
• and
• moving a first piece of data from the first storage device to a second storage device of the plurality of storage devices, access to the second storage device being controlled by a first control device different from the computer, the acquired measurement value of the first access index value for the first piece of data being higher than the acquired measurement value of the first access index value for any other piece of data stored in the first storage device.
