ABSTRACT:
A SCSI initiator system includes a Packetized SCSI Protocol hardware packet engine that automatically transmits Packetized SCSI protocol command blocks to a SCSI target with substantially zero latency between the transmission of adjacent command blocks. The packet engine operates independently of any other hardware circuits in the SCSI initiator that are capable of command management. The SCSI initiator system includes a target execution queue containing at least one hardware I/O control block for a SCSI target. The target execution queue is stored in a memory. The system also includes a Packetized SCSI Protocol hardware packet engine coupled to the target execution queue. The Packetized SCSI Protocol hardware packet engine generates Packetized SCSI Protocol packets using information in the at least one hardware I/O control block directly.
