Availability
With two units, dual loop attachment provides redundancy and no single
point of failure.
Connectivity
SCSI devices may be attached to Fibre Channel storage networks to share
data and increase address space.
Distance
SCSI cable length from hosts to devices is increased from 25m to 10,000m,
facilitating remote or disaster tolerant sites.
Performance
100 Mbytes/sec Fibre Channel (200 Mbytes/sec bi-directional) offers
increased bandwidth when distributing data across multiple SCSI devices.
Reliability
Low error rates, robust error recovery and flow control provide an enterprise
with reliable data delivery.
Scalability
Point-to-point links can be expanded to multi-initiator links supporting inter-
connected servers, tape drives, tape libraries, disk drives and disk arrays.
Flexibility
The PSFR-CP41 allows Fibre Channel initiators to communicate with SCSI
targets, as well as SCSI initiators to communicate with Fibre Channel
targets, simultaneously.
Consolidation
The PSFR-CP41 allowsmultiple servers to share tape drives, tape libraries,
disk drives and disk arrays.
Centralization
The PSFR-CP41 enables existing storage to be moved to a central location
to simplify management and maintenance, and to improve security.
Lower TCO
Improving storage management, maintenance and security can lower Total
Cost of Ownership (TCO) for enterprise storage.

How the PSFR-CP41 Works Introducing the PSFR-CP41
How the PSFR-CP41 Works
The PSFR-CP41 acts as a pass-though device that translates Fibre Channel
FCP to and from a SCSI bus so devices on these two types of media can
communicate with each other. It attaches to either a Fibre Channel or SCSI
host, and transfers the command, data, and status information to SCSI or Fibre
Channel targets. The host passes packets to SCSI or Fibre Channel targets as
if the PSFR-CP41 were just another device along the path.
The PSFR-CP41 provides connections for a single SCSI bus and a Fibre
Channel Arbitrated Loop or Switched Fabric. It takes advantage of Fibre
Channel’s ability to encapsulate SCSI protocol packets to allow ahost with a FC
or SCSI adapter to access SCSI or FC peripheral devices transparently over a
FC connection.
Fibre Channel-to-SCSI configuration
The figure shows a Fibre Channel-to-SCSI configuration. Through the PSFR-
CP41 router, any host on the Fibre Channel loop can access thetape drive and
library on the SCSI bus.
