Abstract
A method of offloading, from a host data processing unit (), the generation of data corruption-detection digests for iSCSI PDUs to be transmitted as TCP segments over respective TCP connections. An iSCSI layer processing software () executed by the host data processing unit provides a command descriptor list () containing command descriptors adapted to identify portions of at least one iSCSI PDU to be transmitted, and data corruption-detection digest descriptors (CRC DESC(PDUa); CRC DESC(PDUb)), each one associated with a respective PDU data corruption-detection digest. An iSCSI processing offload engine () transmits the iSCSI PDU over the respective TCP connection, based on the descriptors in the command descriptor list; during the transmission, the iSCSI PDU data corruption-detection digest are calculated, and the calculated data corruption-detection digest is saved in the corresponding data corruption-detection digest descriptor in the command descriptor list.
