Before you start
Ultrium tape drives are high performance, Ultra 3 SCSI devices designed to operate on a low
voltage, differential SCSI bus (LVDS). They can be connected to a SCSI connection on a server
or fibre channel/SCSI bridge. To get optimum performance from your tape drive you need a
SCSI bus that can transfer data at a rate that supports the tape drive’s maximum burst transfer
speed of 160 MB/second. We recommend an Ultra 3 (160) or Ultra 4 (320) SCSI bus.
Before starting to install your tape drive, you should consider the following:
How do I use the tape drive with my system?
Check the usage models on page 7. This shows how the Ultrium tape drive can be used in
different system configurations; direct attach, network attach and storage area network.
How do I connect the drive to my server or fibre channel bridge?
Your tape drive is supplied with a 68-pin, wide, VHD-to-HD SCSI cable to attach to the host
server or fibre channel bridge.
Fibre channel connection
If you are using your tape drive on a fibre channel (FC) network, you will need a FC/SCSI
bridge with a spare LVDS SCSI port with a 68-pin, very high density (VHD), wide SCSI
connector.
If you are attaching your tape drive to a SAN environment, refer to your SAN solution
collateral or configuration guides for further details.
Server connection
If you are attaching the drive to a server, you will need a properly installed and configured
SCSI host bus adapter (HBA) or a built-in SCSI controller on your server with a spare LVDS
SCSI port with a 68-pin, very high density (VHD), wide SCSI connector.
For optimum performance your tape drive should only be connected to an Ultra 3 (160) or
Ultra 4 (320) host bus adapter or SCSI controller and it should be the only device on the SCSI
bus. Do not attach the drive to the same SCSI bus as your disk drive or RAID controller.
See also Table 1, “supported SCSI bus types,” on page 9.

Do I need additional items for installation?
• If you do not have a spare, suitably rated SCSI connector on your server, you must install a new
HBA (also known as a SCSI card). You will need to purchase and install the new HBA into an
unused, 64-bit PCI expansion slot within your server before installing your tape drive. Full
installation instructions and all necessary cables and mounting hardware are provided in this
kit.
• If you do not have a VHD, wide SCSI connector on your server or bridge, you will need to
purchase and install a VHD-to-HD adapter or use an HD-to-HD cable instead of the supplied
cable.
• If the tape drive is not the only or last device on the SCSI bus, you must terminate the bus with
a multimode terminator. If the tape drive is the only or last device on the bus, then the tape
drive enclosure provides active termination and you do not need to purchase a separate
terminator.

Backup software and drivers
Backup software
For optimum performance it is important to use a backup application that is appropriate for
your system’s configuration. In a direct attach configuration, where the tape drive is attached
to a standalone server, you can use backup software that is designed for a single server
environment. In network configurations you will need backup software that supports enterprise
environments. HP, Veritas, Legato and Computer Associates all provide suitable products.
Further details about these products can be found on the software vendor’s web site.
Make sure you have a backup application that supports Ultriumtape drives and download
any upgrades or patches, if required.
Drivers
Windows users
Before you install the tape drive, download the driver from the manufacturer’s web site. Refer
to the accompanying README file for specific installation instructions for Windows NT and
Windows 2000/XP drivers. This will tell you whether you need to install the driver before or
after installing the tape drive.
UNIX users
The recommended backup applications use the operating system’s standard, built-in device
drivers. To upgrade drivers we recommend that you patch to the latest version of the operating
system or configure device files.
IA64 users
If you are installing on IA64, check the manufacturer’s web site for the latest information on
the availability of backup application upgrades and drivers.

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.

Figure 2: checking the SCSI connection
Step 1: Check the SCSI connection
Use the following questions to help you check your SCSI connection. If you answer ‘Yes’ to all
these questions, you are ready to install your tape drive. If you answer ‘No’, you will probably
need to purchase and install additional items.
1 Are you connecting to a SCSI
bus on a server?
Yes?
2 Is there a spare SCSI port on
the server?
Yes?
3 Is the spare port on an Ultra 3
(160) or Ultra 4 (320) SCSI
bus?
Yes?
4 Will the drive be the only
device on the bus? This is the
recommended configuration.
Do not connect to a RAID
controller channel. This is for
disk drives only.
No?
No?
No?
No?
For fibre channel connections, you need a
fibre channel/SCSI bridge of the correct
specification. Contact your fibre channel
infrastructure vendor for details.
Purchase and install one of the recommended
HBAs into an unused 64-bit PCI expansion
slot. (The HBA can also be installed in a 32bit PCI expansion slot, but performance may
be degraded.)
Performance may be impaired. See table
below. Consider replacing your card with
one of the recommended HBAs.
If you have a spare PCI slot, install a new
Ultra 160 HBA to provide a dedicated SCSI
bus. If you have to configure more than one
drive on the same bus, install an Ultra 4
(320) HBA and make sure the last device on
the bus is terminated.
Yes?
Purchase and install a VHD-to-HD adapter
