Zusammenfassung:Embodiments of the present invention disclose a method, computer program product, and system for data deduplication. Receiving a protocol data unit (PDU) that includes data to be stored on a system and a hash value that corresponds to the data. Determining whether the hash value of the received PDU matches a stored hash value that corresponds to data that is stored in the system. Responsive to determining that the hash value of the received PDU does not match a stored hash value, storing the data included in the received PDU in the system. In another embodiment, the system is an iSCSI attached storage system, and the PDU is an iSCSI PDU.
