Document Type and Number:
Japanese Patent JP6209926
Kind Code:
B2
Abstract:
A storage control apparatus forms a RAID by plural storage media and stores and holds data on a file-by-file basis. A number-of-writable-times management unit manages the number of writable times for each storage medium. A write-destination management unit manages data write destinations in the storage media. When updating write object data whose write destination is one of storage media constituting a group (first storage medium), a relocation unit relocates the write object data by setting a write destination to a second storage medium which is different from the first storage medium. A write-destination update unit updates the data write destinations in the storage media managed by the write-destination management unit according to the relocating. Through the relocating, the storage control apparatus is able to control the number of writable times which decreases along with data writing.
