Abstract
A storage apparatus is provided, including a first storage unit; a load information obtaining unit that obtains load information for each of a plurality of portions defined by dividing the first storage unit; a portion identifying unit that identifies a candidate portion that is to be relocated in the first storage unit based on the load information; a determining unit that determines whether or not data in the candidate portion is allowed to be migrated to a second storage unit, the second storage unit having a performance value higher than a performance value of the first storage unit; an adder that adds the second storage unit, when the determining unit determines that the data in the candidate portion is not allowed to be migrated; and a relocation unit that migrates the data in the candidate portion from the first storage unit to the added second storage unit.
