Processing SCSI Information
Processing SCSI Information
The following describes how the router processes SCSI information:
1. A FC host issues a command. The FC host encapsulates the command in
the FCP protocol and sends the packet to the PSFR-CP41.
2. The FC port in the PSFR-CP41 receives the packet, interprets the FC infor-
mation, and places the packet in buffer memory.
3. The PSFR-CP41's processor interprets the information and programs the
SCSI controller to process the transaction.
4. The SCSI controller sends the command to the SCSI device (target).
Information processing
5. The target interprets the command and prepares to either read or write data.
6. Data flows between the host and target through buffer memory.
7. Response information flows from the SCSI target back to the FC host.
