Fibre Channel with Libraries

NOTE

See “Fibre Channel Cable Connections” on page 1-16 for more
information about installation and configuration.

The Fibre Channel interfaces in library Model 12/140 serve as a bridge
between SCSI and fibre channel by using the following:

• Two actively terminated, 68-pin, fast and wide, high or low voltage

differential SCSI ports that support SCSI sequential access and
medium changer target devices

• FC-PLDA (Fibre Channel - Private Loop Direct Attach) ANSI

standard

NOTE

Libraries that do not have Fibre Channel interfaces only support the
SCSI protocol.

Host Prerequisites

To use Fibre Channel, check the host for the following:

• Fibre Channel backup software, host interface cards, and associated

device drivers.

• Host that acts as an initiator using the Fibre Channel interface to

communicate with Fibre Channel SCSI target devices.

• Backup software with robust error recovery. Fibre Channel is an open

system, similar to LAN. Consequently, Fibre Channel is subject to
data flow interruptions from power cycling, connections,
disconnections, and ESD discharges.
