Abstract
According to the embodiments, a storage array system includes a plurality of storage units, and a host device. The host device determines whether first data, which is restored from data in the storage units other than a replaced first storage unit, is identical with data indicated by a first function. The host device transmits and writes the first data to the first storage unit, when the first data is not identical with the data indicated by the first function. The host device transmits a deletion notification to the first storage unit, when the first data is identical with the data indicated by the first function.
