摘要： The amount of data to be stored in a semiconductor nonvolatile memory can be reduced and overhead associated with data processing can be reduced. When a microprocessor 112 receives a write request from a host computer 300 and data D1 to D3 exist in a cache slot 117, the microprocessor 112 reads the LBA of each piece of the data, manages each piece of the data D1 to D3 using a bitmap table 118 by associating them with their LBAs, generates a specific command CMD based on the LBAs of the data D1 to D3, adds the data D1 to D3 and addresses ADD1 to ADD3 indicating where the data D1 to D3 are to be stored, to the specific command CMD, and sends it to an FMPK 30. The FMPK 130 stores each piece of update data in a specified block in the flash memory 135 based on the specific command CMD.

摘要： Efficient leveling among a plurality of FMPKs 130 including a newly added or replaced FMPK 130. When a storage controller 110 lacks free blocks in real FMPKs 130 and any FMPK 130 of the real FMPKs 130 and an added substitute FMPK 130 are selected as leveling object devices, if the attribute of a block in the real FMPK 130 belonging to the leveling object devices is “Hot,” data larger than a threshold value from among data belonging to that block is migrated to a block in the substitute FMPK 130; or if the attribute of a block in the real FMPK 130 belonging to the leveling object devices is “Cold,” data smaller than the threshold value from among data belonging to that block is migrated to a block in the substitute FMPK 130.

摘要： For a storage apparatus where flash memory disks and hard disks coexist, high-density mounting of flash memory modules is achieved. The storage apparatus includes flash memories and a storage controller. A second storage apparatus including magnetic disks is connected to the storage apparatus. The storage controller can form a storage area using a flash memory or a magnetic disk to create a logical volume. When an input/output request is issued from a host computer, if a storage area is formed with a flash memory, the storage controller directly accesses the flash memory to handle the request. When the storage apparatus defines a storage area formed with a flash memory, the storage apparatus defines the storage area by adding up the capacity of a storage area to be provided for the host computer and a substitute area capacity determined in consideration of restrictions on the number deletions of the flash memory.

摘要： To extend endurance and reduce bit cost, a method and a storage apparatus are provided, which storage apparatus includes a controller and a semiconductor storage media that includes a first storage device and a second storage device having an upper limit of an erase count of data smaller than the first storage device. Area conversion information includes correspondence of a first address to be specified as a data storage destination and a second address of an area in which data is to be stored. A rewrite frequency of stored data is recorded for each area. The controller selects an area corresponding to the first address, determines whether or not the rewrite frequency of the selected area is equal to or larger than a first threshold value, when the rewrite frequency is equal to or larger than the threshold value, selects an area to be provided by the first storage device, and when the rewrite frequency is smaller than the threshold value, selects an area to be provided by the second storage device and maps the address of the selected area to the first address.
