SYSTEM AND METHOD FOR PRIORITIZING ISCSI DATA TRANSMISSION USING DATA CENTER BRIDGING ENABLED SWITCHES

摘要

A method of prioritizing data transmissions between a SCSI initiator and a SCSI target in a network system with DCB enabled switches. The method includes a switch controller detecting a SCSI set priority response transmitted via a first pair of swit ch ports from a SCSI target to a SCSI initiator, which communicate SCSI messaging and transmit I/O data via the first pair of switch ports. In response to detecting the SCSI set priority response, the priority data established by the SCSI target is retrieved and, base d on the retrieved priority data, the switch controller autonomously sets the DCB priority for the first pair of switch ports to a first DCB priority value correlated to the retrieved priority data. Transmission of the I/O data between the SCSI initiator and the SCSI target is supported with a priority of the first pair of switch ports set to the first DCB priority value.
