Abstract: According to a data deduplication system and method for a storage array is provided in embodiments of the present invention, where a controller is connected to a cache device via a switching device, the cache device calculates an eigenvalue of a to-be-deduplicated data block, the controller queries an eigenvalue index set of data blocks according to the eigenvalue of the to-be-deduplicated data block, and when the same eigenvalue is not found, the controller sends a cache address of the to-be-deduplicated data block in the cache device to a controller of a target storage unit such as a hard disk drive, and the controller of the target hard disk reads the to-be-deduplicated data block from the cache address of the data block.
