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： The present invention efficiently uses the storage capacity in a storage system that has flash memory as a storage medium.A storage system has a storage controller and a flash memory module that is connected to the storage controller. The storage controller manages the status of a storage area in a flash memory chip of the flash memory module. When a portion of the storage area in the flash memory chip becomes unwritable, the storage controller carries out control so as to use a free storage area as an alternate area for the unwritable storage area, and to store data that has been stored in the unwritable storage area, in the alternate area.

摘要： In a storage system which includes a plurality of microprocessors, it is desired to prevent delay in I/O responses due to synchronous processing waiting for asynchronous processing, while still ensuring the throughput of asynchronous processing. In a plurality of microprocessors possessed by a controller, synchronous processors and asynchronous processors are mixed together. The synchronous processors are microprocessors whose duty is to perform synchronous processing and not to perform asynchronous processing. And the asynchronous processors are microprocessors whose duty is to perform asynchronous processing and not to perform synchronous processing.
