Abstract:
A storage system according to an aspect of the present invention includes one or more storage devices for storing write data to which a write request from a host computer is directed, and a storage controller that provides one or more volumes to the host computer. Further, the storage system manages the time when a write request is last received from the host computer for each partition within the volume. Then, the storage controller performs a deduplication process upon detecting the partition not receiving a write request for a predetermined time or more from the time when the write request is last received.

Claim (Index 8):
The method for controlling a storage system according to  claim 7 ,\n wherein the storage controller manages a state for each partition, wherein the state of the partition includes a first state which is a state in which the deduplication process is not performed, a second state which is a state in which the deduplication process is performed, and a third state which is a state in which the partition is returned from the second state to the state before the deduplication process is performed, and in the step of performing the deduplication process, when a deduplication ratio of the partition is less than a predetermined threshold resulting from that the storage controller performs the deduplication process on the partition of the first state, the storage controller changes the state of the partition to the third state.
