Abstract:
1. A method for transmitting an internet small computer system interface (iSCSI) command with a priority level based on a SCSI task priority, the method comprising: receiving a SCSI command descriptor block having the SCSI task priority; translating the SCSI task priority to an Ethernet user priority by mapping the SCSI task priority to the Ethernet user priority using a single priority map, wherein a first set of priorities that includes three different lower-level SCSI task priorities maps to a single lower-level Ethernet user priority, a second set of priorities that includes two different intermediate-level SCSI task priorities maps to a single intermediate-level Ethernet user priority, and a third set of priorities that includes a single higher-level SCSI task priority maps to a single higher-level Ethernet user priority; generating an iSCSI request command descriptor block having the Ethernet user priority based on the SCSI command descriptor block; and transmitting the iSCSI request command descriptor block to a transport control protocol layer for transmission over an Ethernet network.
