A non-transitory computer readable storage medium that stores a storage control program causing a computer to execute a control process of a storage including a first storage device with first access speed, and a second storage device with second access speed that is slower than the first access speed, includes monitoring access frequency to data in the first and second storage devices; relocating data, the access frequency of which exceeds a first reference value, in the second storage device, to the first storage device; and conducting a overload processing of retaining, in the cache memory, at least a part of the data in the second storage device when the second storage device is in an overload state. the access frequency monitoring is executed in a state where the partial data is retained in the cache memory, and the relocating is executed based on the access frequency to the partial data.
