3.4 SAS interface
The drive has a Gbps SAS (Serial Attached SCSI) host interface.
A drive with a SAS (Serial Attached SCSI) interface can be linked directly to
controllers. SAS is a performance improvement over traditional SCSI because
SAS enables multiple devices (up to 128) of different sizes and types to be
connected simultaneously with thinner and longer cables; its full-duplex signal
transmission supports 6.0 Gb/s. SAS drives will auto-negotiate speed. There
are no configurable topologies thus no setup is required for SAS interface.

Introduction
3.5 Cartridge compatibility
The drive supports the following data cartridges:
– Ultrium-6 data cartridge at 2.5:1 compression (Read/Write)
– Ultrium-5 data cartridge at 2:1 compression (Read/Write)
– Ultrium-4 data cartridge at 2:1 compression (Read only)
IUltrium-1, Ultrium-2, and Ultrium-3 data cartridges are not supported.
3.6 Backup performance/capacity
The backup performance and backup capacity that can be used in one data
cartridge varies depending upon the following factors:
– The conditions (attrition, dust, etc.) of the recording surface of the data
cartridge to be used
– The dust and dirt condition of the product's magnetic head
– The data compression rate
– The workload on the server
3.7 LTO-6 tape drives and encryption
The LTO-6 tape drive include hardware capable of performing data encryption
at full speed while writing data, and decrypting when reading.
Encryption is the process of changing data into a form that cannot be read until
it is deciphered, protecting the data from unauthorized access and use. LTO-6
tape drives use the strongest version of the industry-standard AES encrypting
algorithm to protect your data.
To make use of this feature you need:
– A backup application that supports hardware encryption
– Encryption is possible on LTO-4, LTO-5, and LTO-6 media.
– The LTO-4 data cartridge is read only on LTO-6 tape drive.

3.7.1 When should I use encryption?
Your company policy will determine when you need to use encryption. For
example, it may be mandatory for company confidential and financial data, but
not for personal data. Company policy will also define how encryption keys
should be generated and managed. Backup applications that support
encryption will generate a key for you or allow you to enter a key manually.
IEncryption with keys that are generated directly from passwords or
passphrases may be less secure than encryption using truly random
keys. Your application should explain the options and methods that are
available. Please refer to your application's user documentation for more
information.
3.7.2 How do I enable encryption?
Hardware encryption is turned off by default and is switched on by settings in
your backup application, where you also generate and supply the encryption
key. Your backup application must support hardware encryption for this feature
to work.
3.7.3 What happens if I don't remember the key?
If you are unable to supply the key when requested to do so, neither you nor
Technical Support will be able to access the encrypted data.
This guarantees the security of your data, but also means that you must be
careful in the management of the encryption key used to generate the tape.
WWARNING!
You should keep a record or backup of your encryption keys and store
them in a secure place separate from the computer running the backup
software.
3.7.4 Does encryption affect tape drive performance?
Hardware encryption can be used with or without compression and without
speed or capacity impact.

LTO-6 Half-Height SAS Tape Drive 17
Introduction
3.7.5 Does the tape drive encrypt media in an earlier LTO
format?
Encryption is supported only on LTO Ultrium-6 media, LTO Ultrium-5 media, and
LTO Ultrium-4 media.
Encrypted LTO Ultrium-6, LTO Ultrium-5 and LTO Ultrium-4 tapes can be read
on any compatible LTO tape drive that supports hardware encryption. (LTO-6
tape drives can read and write encrypted LTO Ultrium-6 media and LTO
Ultrium 5 media. LTO-6 tape drives can read encrypted LTO Ultrium-4 media.)
Hardware encryption is not supported on any earlier LTO media, such as LTO
Ultrium-3 media.
3.7.6 Where can I get more information?
For detailed instructions about enabling encryption please refer to the
documentation supplied with your backup application. This will also highlight
any default states, for example when copying tapes, that may need changing if
using encrypted tapes.

3.8 LTO-6 tape drives and partitioning
The LTO-6 tape drive supports up to four tape partitions, when used with LTO
Ultrium-6 cartridges. Tape partitioning is not supported with WORM (Write Once
Read Multiple) cartridges or with earlier generations of cartridge. It is not
supported on earlier-generation tape drives. If you insert a partitioned tape into
a tape drive that does not support partitioning, it will be ejected.
To check for the latest information about support for partitioning and any
required firmware upgrades, refer to the following web sites:
–http://support.ts.fujitsu.com/com/support/downloads.html
–http://jp.fujitsu.com/platform/server/primergy/downloads/
Refer to your backup application's documentation for information about creating
and using partitions on the tape drive.
3.9 Feature Switches
The feature switch is located on the rear panel of the tape drive. Refer to "Rear
panel of the SAS drive" on page 14 for the location of the switch. The switch
positions are labeled 1 through 8. The on and off positions are marked on the
switch. The default settings for the feature switches are all switches placed in
the “OFF” position. Do not change the default settings.
3.10 Supported device drivers
Device drivers enable the drive to interact with a variety of servers. Current
drivers, firmware and tools can be found on:
– DVD “Server View Suite“
–http://ts.fujitsu.com/support/downloads
Search for “lto“ in fulltext search or search based on the server system under
industry standard server.
–http://support.ts.fujitsu.com/com/support/downloads.html
Search for "Storage" and "LTO6".
For the Japanese market please use the URL:
http://jp.fujitsu.com/platform/server/primergy/downloads/
Please use the mentioned web links also for upgrade check and if the driver on
Server View Suite DVD is an old version or lost/missing.

4 Installing the drive
Before starting this installation, read these instructions and compare them to the
drive installation instructions for your server.
4.1 Avoiding drive damage
To avoid static electricity damage when handling the drive, use the following
precautions:
●Limit your movement. Movement can cause static electricity to build around
you.
●Always handle the drive carefully. Never touch exposed circuitry.
●Prevent others from touching the drive.
●Before unpacking and installing the drive into a server, touch its static-
protective packaging to an unpainted metal surface on the enclosure for at
least two seconds. This reduces static electricity in the packaging and your
body.
●When possible, remove the drive from its static-protective packaging and
install it directly into an enclosure without setting it down. When this is not
possible, place the drive’s packaging on a smooth, level surface and place
the drive on the packaging.
●Do not place the drive on the cover of the enclosure or on any other metal
surface.

4.2 Installation overview
1. "Install the SAS drive connector" on page 20
2. "Mount the drive into a PRIMERGY server" on page 20
3. "Install device drivers" on page 21
4.3 Install the SAS drive connector
Install the customer-supplied SAS drive connector to the rear panel of the drive
(1 in figure 3 on page 14). The SAS connector also includes the power
connector for the drive.
4.4 Mount the drive into a PRIMERGY server
When mounting the drive into a server:
●Use an appropriate screw length.
●Ensure that no objects such as screw heads, cables, or adjacent devices,
are pressing against the frame.
●Do not obstruct the ventilation slots at the rear of the drive.
●Allow sufficient space for accessing the drive’s front panel controls.
To mount the drive into a server:
1. Remove the 5 1/4 inch cover of your server (refer to the instructions in the
documentation provided with your server).
2. Place the drive into the server so that the tape load compartment of the drive
faces the tape load compartment of the server.
3. Insert four screws into the lower mounting holes of the side brackets located
on the left and right sides of the chassis.
