Usage models
The tape drive can be directly attached to a VHD SCSI connector on a server or fibre channel
bridge. It can be used in a stand-alone (direct attach) or network environment (both Local
Area Network and Storage Area Network).
To connect to fibre channel you must purchase and install a supported fibre channel/SCSI
bridge.
This guide describes how to connect the tape drive to the VHD SCSI connector on the server
or bridge. The instructions are appropriate for all environments, but network users may need
to take additional steps to ensure that their system is configured for optimum performance.
See "Optimizing performance" on page 23.
Direct attach
The tape drive is directly attached to a single server via a SCSI link or a fibre channel/SCSI
bridge.
Network attach (LAN)
The tape drive is directly attached to a network storage server that can be accessed by a
number of clients or workstations. As with the direct attach model, the connection is via a
SCSI link or fibre channel/SCSI bridge to the storage server.
Storage area network (SAN)
The tape drive is attached to the SAN via a fibre channel/SCSI bridge. The Ultrium tape drive
can be used to back up any device in the fibre channel fabric; in practise, the system
administrator decides which devices will be able to see and access the tape drive.
Fibre channel configurations
This guide describes how to physically attach the tape drive to one of the supported fibre
channel/SCSI bridges. It does not describe how to configure your fibre channel infrastructure
or SAN network and associated software to use the tape drive. This is a complex area and
users are advised to refer to their SAN documentation or contact their SAN system
administrator or supplier for technical support.
