How the PSFR-CP41 Works Introducing the PSFR-CP41
How the PSFR-CP41 Works
The PSFR-CP41 acts as a pass-though devicethat translates Fibre Channel
FCP to and from a SCSI busso devices on these two types of media can
communicatewith each other. It attaches to either a Fibre Channel or SCSI
host,and transfers the command, data, and status information to SCSI or Fibre
Channeltargets. The host passes packets to SCSI or Fibre Channel targets as
if the PSFR-CP41 were justanother device along the path.
The PSFR-CP41 provides connectionsfor a single SCSI bus and a Fibre
Channel ArbitratedLoop or Switched Fabric. It takes advantage of Fibre
Channel’sability to encapsulate SCSI protocol packets to allowa host with a FC
orSCSI adapter to access SCSI or FC peripheral devices transparently over a
FC connection.
Fibre Channel-to-SCSI configuration
The figure showsa Fibre Channel-to-SCSI configuration. Through the PSFR-
CP41router, any host on the Fibre Channel loop can access the tape drive and
library on the SCSI bus.
