In default configuration, the Quantum ATL P-Series tape library is
controlled by a host computer through a SCSI differential bus that uses
the SCSI-2 medium changer command set. There is also an RS-232
diagnostic port interface.
Through the installation of the FC230 Router with Prism
Architecture™, you can easily convert the ATL P-Series library from a
SCSI host interface to Fibre Channel. This document describes the
FC230 router, including configuration procedures common to ATL P-
Series libraries.
For a complete description of ATL P-Series library operating
procedures, refer to the appropriate ATL P-Series Library User’s
Guide.
Fibre Channel
Description
0
Fibre Channel is a serial data transfer architecture for use with
computers and mass storage devices. Fibre Channel is rapidly
emerging to challenge SCSI as the interface of choice for host-to-
storage applications.
Fibre Channel advantages include:
• Up to 500-meter connection range
• 1 GB/S data transfer rate
• Support of up to 126 devices on a loop
• Support of 24-bit addressing for over 16 million devices in point-
to-point mode or fabric
• Operating system independence
• Interconnect flexibility
• Full direct connectivity between all ports on a network, increasing
the total throughput of all devices on a network

Once the FC230 router is installed and tested, the library operates
exactly the same as a ATL P-Series library with a SCSI host interface.
Note:
The term “ATL P-Series” refers to the following ATL Tape
Library™ models: P2000, P3000, P4000, and P7000.
