20090063883 | STORAGE SYSTEM AND POWER CONSUMPTION REDUCTION METHOD FOR THE SAME - This invention achieves data capacity efficiency via data de-duplication and maximizes a power-saving effect by disk operation control. In a storage system, when data is received from a computer, a value representing the bit string for the data is calculated and whether or not a value identical to the calculated value is stored in a data management table is judged. If it is judged that an identical value is not stored, the received data is registered in the data management table and stored, based on a group management table, in disk device(s) associated with a logical unit number of a logical unit constituting an active group. Meanwhile, if it is judged that an identical value is stored, the received data is stored in disk device(s) based on the group information managed in the group management table and the management information managed in the data management table. | 03-05-2009 |
