Introduction

The ATL M1500 tape library can contain up to two tape drives and up
to 21 DLT/SDLT cartridges and 25 LTO cartridge. The ATL M1500
library is controlled by a host computer via a SCSI differential bus
using the SCSI-2 medium changer command set. There is also a RS-232
diagnostic port interface.
The ATL M1500 Prism Architecture™ allows for easy conversion from
the SCSI host interface to a Fibre Channel host interface by installing
the FC310 Router option. This document is provided to end users of
the ATL M1500 library to describe the FC310 Fibre Channel host
interface option.
For a complete description of the ATL M1500 library operating
procedures, see the Quantum ATL M1500 User’s Guide (PN 6421000).
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:
• Connection distances with the FC310 option of up to 500 meters
• 1 GB/S data transfer rates
• Support for up to 126 devices on a loop
• Support for 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
• Fibre Channel fabric switches provide full direct connectivity
between all ports on a network, which can increase the total
throughput of all devices on a network.
FC310 Router
Operation

Once the FC310 Router SCSI to Fibre Channel option is installed and
tested, the library operates exactly as a ATL M1500 library with a SCSI
host interface. User operation of the library via the graphical user
interface (GUI) panel is unchanged.
