Scsi To Fibre Channel Protocol Process - HP StorageWorks M2402 User Manual

SCSI to Fibre Channel Protocol Process

In this example, a SCSI host (initiator) on the SCSI bus issues commands and the
information is passed through the router to a target on the Fibre Channel Storage
Area Network (FC-SAN).

Item
A SCSI host issues a command to the router.
The SCSI controller in the router interprets the command and
places it in buffer memory.
The router processor interprets data and programs the router
Fibre Channel controller to process the transaction.
The router Fibre Channel controller translates data into an FCP
protocol packet and sends it to the Fibre Channel target.
The Fibre Channel target interprets the FCP protocol packet and
executes the command.
