Abstract:
One embodiment of the present invention sets forth a technique for mapping a small computer system interface (SCSI) architecture model-3 (SAM-3) task priority to an IEEE Standard 802.1q tag control information (TCI) field. Four bits that define a SAM-3 task priority are mapped to the three user priority bits within a standard 802.1q TCI field. By enabling the SAM-3 task priority of a given SCSI command to determine the user priority within a related IEEE 802.1q Ethernet frame, the Ethernet network is enabled to substantially honor the requested task priority for the SCSI command.
