(1) The host issues a SCSI command. The FC adapter encapsulates the command in the
FC protocol and sends the packet to the SSB.
(2) The FC adapter in the SSB receives the packet, strips the header, interprets the FC
information, and places the packet in memory.
(3) The processor interprets the SCSI information and programs the appropriate SCSI and
FC adapter to process the transaction.
(4) The SCSI adapter sends the command to the SCSI device (target).
(5) The target interprets the command and prepares to act.
Data flows from the target to the host through memory.
