Abstract:
Management information is provided to control a storage including storage-areas so that each storage-area includes a set of data-areas allocated from each storage-area and each set of data-areas has a data-area size that is a different integer multiple of an access unit of the storage. Logical address information stores information identifying a data-area into which target-data obtained by compressing data has been written, in association with a logical address of the data. Upon reception of the data and the logical address of the data, the apparatus identifies the management information corresponding to a data-area size greater than or equal to a size of the target-data, writes the target-data into an unused data-area of one of the sets of data-areas corresponding to the identified management information, and stores, in the logical address information, information identifying a physical address of the unused data-area in association with the logical address of the data.

Claim (Index 1):
An apparatus comprising:\n a memory configured to store management information including first and second management information, and logical address information used to control a storage including a first storage area and a second storage area, the first storage area including a first set of data areas allocated from the first storage area, each of which has a first size that is an integer multiple of an access unit of the storage, the second storage area including a second set of data areas allocated from the second storage area, each of which has a second size that is an integer multiple of the access unit of the storage and differs from the first size, the first management information including first identification information that identifies a physical address of each of the first set of data areas in the first storage area and first status information indicating a usage status of each of the first set of data areas, the second management information including second identification information that identifies a physical address of each of the second set of data areas in the second storage area and second status information indicating a usage status of each of the second set of data areas, the logical address information storing target identification information identifying a target data area that is a data area among the first and second sets of data areas, into which target data obtained by compressing write data to be written into the storage has been written, in association with a logical address of the write data; and a processor coupled to the memory and configured to:\n upon reception of the write data and a logical address of the write data, identify target management information that is one of the first and second management information corresponding to a size greater than or equal to a size of the target data, \n write the target data into an unused data area of a target set of data areas that is one of the first and second sets of data areas corresponding to a target storage area, the target storage area being one of the first and second storage areas corresponding to the identified target management information, and \n store, in the logical address information, information identifying a physical address of the unused data area in association with a logical address of the write data.
