Control technology for storage system

A computer program product for managing a storage system connected to a first computer, wherein the first computer has a file system to convert between file data and block data, wherein the file data is identified in file units, wherein the block data is identified in block units, wherein the storage system has a first storage area for storing the block data received from the first computer, the computer program product comprising:

• a computer-readable medium;
• and
• a computer program stored on the computer-readable medium, the computer program comprising:
• a program instruction for identifying a type of the file system that is available in the first computer;
• a program instruction for selecting the file system of the identified type from among a plurality of the file systems;
• and
• a program instruction for executing conversion of the block data into the file data using the selected file system, wherein the block data is acquired from the first storage area.

A storage system providing a first storage area to a first computer, wherein the first computer has a file system, a first storage area management module and a second storage area management module, wherein the file system executes conversion between file data and block data, wherein the file data is identified in file units, wherein the block data is identified in block units, wherein the first storage area management module divides the first storage area storing the block data into a plurality of first divided storage areas, wherein the second storage area management module configures a second storage area or second divided storage areas, wherein the second storage area is configured using the plurality of the first divided storage areas, wherein the second divided storage areas are configured by dividing the configured second storage area, the storage system comprising:

• a first interface for sending and receiving the block data with the first computer;
• a storage device having the first storage area;
• a type management table that includes arrangement information and information of each type of the file system, the first storage area management module, and the second storage area management module that are available in the first computer, wherein the arrangement information represents arrangement of the first divided storage areas, the second divided storage areas, and the second storage area respectively configured in the first computer, wherein the information of each type is associated with the arrangement information;
• a type identification module that identifies the each type of the file system, the first storage area management module, and the second storage area management module that are available in the first computer with reference to the type management table;
• a plurality of different types of the file system;
• a plurality of different types of the first storage area management module;
• a plurality of different types of the second storage area management module;
• a selection module that selects the identified type of the file system from among the plurality of the file systems, wherein the selection module additionally selects the identified type of the first storage area management module from among the plurality of the first storage area management modules, wherein the selection module additionally selects the identified type of the second storage area management module from among the plurality of the second storage area management modules;
• and
• a data conversion module that acquires the block data stored in the first storage area, wherein the data conversion module converts the acquired block data into the file data using the selected file system, the selected first storage area management module, and the selected second storage area management module.
