Abstract
A storage system includes: a central processing unit; a main memory; first management information that associates a hash value of received data with an address in a volume; and an I/O processing package. The I/O processing package includes an I/O processor and an I/O memory. The I/O processor executes protocol processing. The I/O processor executes at least a part of search processing of an address associated with a hash value of first received data in the first management information. The central processing unit controls execution of deduplication processing of the first received data based on data of an address associated with the hash value of the first received data.
