Patent attributes
A storage control apparatus comprises a storage unit, an association unit, and an execution unit. The storage unit stores association information showing multiple physical chunks which are configured in a physical address space of a nonvolatile semiconductor memory, multiple logical storage areas which are configured in a logical address space of the nonvolatile semiconductor memory, multiple logical chunks which are respectively associated with the multiple physical chunks, and an association between a logical storage area and a logical chunk. The association unit changes the association by changing the association information in accordance with a state of the nonvolatile semiconductor memory, and identifies based on the association information a physical storage area corresponding to a logical storage area specified in an input/output request from a computer. The execution unit executes the input/output request with respect to the identified physical storage area.
