The Quantum ATL P4000/P7000 Series automated tape libraries are 

controlled by a host computer via a SCSI differential bus using the 

SCSI-2 medium changer command set. There is also an RS-232 

diagnostic port interface.
The P4000/P7000 Prism Architecture™ allows for easy conversion 

from the SCSI host interface to a Fibre Channel host interface. This 

document describes upgrading a standard P4000/P7000 equipped 

with a SCSI host interface to a Fibre Channel host interface using a 

Prism FC470 Upgrade kit.

Fibre Channel is a serial data transfer architecture for use with 

computers and mass storage devices that is rapidly emerging to 

challenge SCSI as the interface of choice for host-to-storage 

applications.
Fibre Channel advantages include:
• Connection distances with the Quantum ATL FC470 option up to 

500 meters

• 2 GB/Sec data transfer rates
• Supports up to 126 devices in a loop mode
• Supports 24-bit addressing for over 16 million devices in point-to-

point mode or fabric, when using a Fibre Channel switch or 

multiple Fibre Channel switches.

• Operating system independence
• Interconnect flexibility

Once a Prism FC470 Router option is installed and tested, the library 

operates exactly as a P4000/P7000 with a SCSI host interface. 

Operation of the library via the graphical user interface (GUI) is 

unchanged.

The following tables provide a list of supported Fibre Channel host 

bus adapters (HBAs) and switches that have been tested at the time of 

this printing. For an updated list of supported Fibre Channel HBAs 

and switches, please see
