Method and system for flow control during the data out phase of the packetized SCSI protocol

摘要

A method for flow control by a SCSI system using a Packetized SCSI Protocol includes transferring a data packet information unit in a Packetized SCSI Protocol Data Out phase between a SCSI initiator and a SCSI target over a SCSI bus. The method also includes generating a signal on said SCSI bus by said SCSI target in said Packetized SCSI Protocol Data Out phase to indicate whether another data packet information unit is to be accepted in said Packetized SCSI Protocol Data Out phase by said SCSI Target.
