Introduction

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
Description
0
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
Prism FC470 Router
Operation
0
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.
