Information processing apparatus, computer-readable recording medium having storage control program stored therein, and method of controlling storage

A non-transitory computer-readable recording medium having a storage control program stored therein,

• the storage control program making a first processing unit execute processing to:
• manage files in a storage apparatus and accesses to the files;
• and
• determine a migration target file from the files based on a history of the accesses to the files, the migration target file being to be migrated from a second storage medium to a first storage medium in the storage apparatus, the first and second storage mediums having different performances, and
• the storage control program making a second processing unit execute processing to:
• control migrations of the files between the first storage medium and the second storage medium;
• and
• migrate the migration target file from the second storage medium to the first storage medium.

A method of controlling a storage, the method comprising:

• by a first processing unit,
• managing files in a storage apparatus and accesses to the files;
• and
• determining a migration target file from the files based on a history of the accesses to the files, the migration target file being to be migrated from a second storage medium to a first storage medium in the storage apparatus, the first and second storage mediums having different performances, and
• by a second processing unit,
• controlling migrations of the files between the first storage medium and the second storage medium;
• and
• migrating the migration target file from the second storage medium to the first storage medium.
