Which operating systems are supported?
1018931DAT SCSI Tape Drives

Chapter 1–Before you start
DAT tape drives can be connected to servers running under Windows®,
Linux and other major operating systems. Please visit the support pages at
http://www
.tandbergdata.com for the most recent information about the
operating system versions that are supported.
How do I connect the drive to my server?
The following guidelines apply:
• For optimum performance the drive should be the only device on the
SCSI bus.
• Always terminate the SCSI bus.
• Do not attach the drive to the same SCSI bus as your disk drive or to a
RAID controller (unless you are connecting to a server with a Smart Array
6i RAID controller).
You will need a properly installed and configured SCSI host bus adapter
(HBA) or a built-in SCSI controller on your server and a suitably-r ated SCSI
cable.
Please visit the support pages at http://
www.tandbergdata.com to ensure that y ou are connecting
Note:
to a supported HBA running the recommended firmware
version.
Internal drives
The tape drive is installed into a spare, industry-standard, 5¼-inch drive bay
in your server and is attached to the SCSI bus of the host server. Use an
LVDS-compatible ribbon cable to connect the tape drive to a spare 68-pin,
high density (HD), wide SCSI connector on the host server.The cable must
be terminated.
External drives
A 68-pin, wide, VHD-to-HD SCSI cable is required to attach the tape drive
to the host server. If your server has an HD SCSI port, you must either
purchase and install a VHD-to-HD adapter or use an HD-to-HD cab le. please
visit the support pages at http://www
.tandbergdata.com for recommended
products.

How do I connect the drive to my server?
Why is the SCSI bus type important?
The SCSI bus type determines the speed at which data can be transferred
between devices on the bus and the maximum length of cable that can be
used.The drives support a burst transfer rate of 160 MB/sec.To benefit
from this level of performance, it is important to ensure that the drives are
connected to a SCSI bus of a similar or higher specification.This means
that you need:
• An Ultra160 or Ultra320 SCSI bus. If you attach the drive to a lower
specification SCSI bus, it will still work but data will not be transferred
as quickly.
• LVD-rated SCSI cabling and terminators. The LVD interface enables
the data to be transferred at the drive's maximum rate.
The drives are not compatible with high voltage diff erential
(HVD) SCSI devices.
Note:
Table 1-1 Supported SCSI bus types
SupportedSCSI Bus Type
Yes. These are recommended configurations.
Ultra160 LVD, Ultra320 LVD
Yes. These are supported, but performance may
be impaired.
Ultra2 LVD, Ultra
Wide LVD
Yes. But this is not a recommended configuration
as it will restrict performance.
Ultra wide, singleended
Yes. But this is not recommended as it will se v erely
restrict performance and you will need a suitable
cable or adapter.
Ultra narrow , singleended
No. The drive will not work and you may damage
the drive or controller
High V oltage Differential
What are the mounting requirements for an internal tape drive?
You need one industry-standard, 5¼-inch, half-height bay in which to install
the Tandberg Data DAT tape drive. For many servers, no mounting tray or
rails are required. Devices simply slide into the server's chassis and are
fixed with screws. Other servers have built-in trays or rails.
Some servers use non-standard mounting rails and do not include spares.
If this is the case with your system, you will hav e to order these accessories
from the server manufacturer before you can install the tape drive.

Drivers
One driver is required in order to use DAT SCSI tape drives.
The manufacturer's Tape driver is suitable for use in most applications, but
refer also to the documentation of your software application to ensure you
are using the recommended driver.
On Windows systems, we strongly recommend that you use the installer
package supplied by your man ufacturer to install the driv ers. Updates to the
drivers may be provided from time to time on http://www
.tandbergdata.com.
We recommend that these are installed after using the installer package.
On Linux and UNIX operating systems, drivers are included with the operating
system and should be loaded automatically.To upgrade drivers we
recommend that you patch to the latest version of the operating system.
Backup software
For optimum perf ormance 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, y ou can use backup
software that is designed for a single server environment. In network
configurations you will need backup software that supports enterprise
environments.
Further details about suitable products can be found on http://
www.tandbergdata.com. It is important to check for software compatibility
and install any recommended upgrades.
Certain backup applications require you to use their own
Tape driver instead of the manufacturer's Tape driver.
Note:

Power requirements
The NT backup application is compatible with DAT tape
drives, but the user must always choose 4 mm tape even
Note:
when using 8 mm tape with a Tandberg Data DAT 160
tape drive.

Installing an internal DAT
tape drive
In this chapter:
•“Check the drive's SCSI ID” on page 17
•“Prepare mounting bay” on page 18
•“Attach mounting hardware” on page 19
•“Attach power and SCSI cables” on page 21
•“Secure the drive” on page 23
Please refer to “Installing an external DAT tape drive” on page 25, if you
are installing an external DAT tape drive.
Check the drive's SCSI ID
Your DAT drive is shipped with a default SCSI ID of 3. Each device on the
SCSI bus must hav e an unique SCSI ID number .The drive can be assigned
any unused ID between 0 and 15. Do not use SCSI ID 7, which is reserved
for the SCSI controller. SCSI ID 0 is typically assigned to the boot disk and
should also not be used unless the tape drive is on a dedicated SCSI bus.
Static electricity can damage electronic components.
Always wear an antistatic wriststrap if possib le. If not,
Caution
to equalize the electromagnetic charges, touch a
bare metal part of the server (such as the back plate)
before you remove the tape drive from its bag.
17
#August 2009
Figure 2-1 Checking the SCSI ID
1. Determine whether you need to change the SCSI ID from the default
of 3.
2. Change the tape drive's SCSI ID, if necessary.
The SCSI ID is set using jumpers on a set of pins at the rear of the
drive, as shown in figure 3. Use tweezers or small pliers to move the
jumpers to the pattern corresponding to the ID you want. Do not remove
the TP jumper. It should always be set.
Spare jumpers will be attached to the drive.The
drive is supplied with compression enabled. It can
be disabled by removing the compression jumper,
but this is not generally recommended.
Note:
Prepare mounting bay
You need one industry-standard, 5¼-inch bay in which to install the DAT
tape drive.
To avoid personal injury or damage to the server or
tape drive, ensure that the server is disconnected
Warning
from the mains power supply while you install the
drive.
