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.

14 LTO-6 Half-Height SAS Tape Drive

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)

I Ultrium-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.

LTO-6 Half-Height SAS Tape Drive 15

Introduction

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.

I Encryption 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.

W WARNIN G!

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.

16 LTO-6 Half-Height SAS Tape Drive

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.

LTO-6 Half-Height SAS Tape Drive 17

Introduction

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 (W

ead Multiple) cartridges or with earlier generations of cartridge. It is not

R 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/

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.

Operating the Drive

5.7 Cleaning the Drive Head

Attention: When cleaning the drive head, use a LTO Ultrium Cleaning

Cartridge.

Clean the drive head whenever "C" displays on the Single-character Display and the Fault status light is flashing amber once per second.

To clean the head, insert the cleaning cartridge into the tape load compartment (see "Front panel of drive" on page 13). The drive performs the cleaning automatically in less than three minutes then ejects the cartridge.

I The drive will automatically eject an expired cleaning cartridge.

An LTO Ultrium Cleaning Cartridge is valid for 50 uses.

5.8 Cautions Concerning Backup

5.8.1 Ejecting the data cartridge after backup

● Do not leave the data cartridge in this product.

Doing so makes the data cartridge wear faster, because the longer it is used, the faster it wears. The tape recording surface of the data cartridge is exposed when inserted in this product and if it is left in this state for a long time it will easily be affected by suspended particles of dust. Insert the data cartridge just before the backup operation, and remove it immediately after the operation.

● Do not turn off the power with the data cartridge inserted.

If the power is turned off with the data cartridge inserted, it takes a while before this product can be used after the next power-on.

LTO-6 Half-Height SAS Tape Drive 31

Operating the Drive

5.8.2 Data compression rate

This product has a data compression function included in the hardware.

Although the data compression rate is approximately 250%, it varies depending on the data content.

Data that has already been compressed by software is not effected by this product.

Some backup software has a data compression function prior to transfer, however, do not compress data by software if the hardware compression function is on.

5.8.3 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

5.8.4 Points to note during system configuration

When repeatedly using a single data cartridge, all the data can be lost if the backup fails. Also, if a backup data cartridge becomes damaged, the data cannot be recovered.

Damage in the event of a failure can be minimized if two or more data cartridges are used for backup operation. For example, use different data cartridges for each day of the week.

Using Ultrium Media

6.3 Using the correct media

6.3.1 Cleaning cartridges

Use the universal cleaning cartridge. It may be used for up to 50 cleans.

6.3.2 Data cartridges

LTO-6 tape drives use the LTO-6 tape cartridges referred to in chapter

"Cartridge Compatibility" on page 36. These are single-reel cartridges that

match your drive's format and are optimized for high capacity, throughput and reliability. Compatible media can be recognized by the Ultrium logo, which is the same as the logo on the front of your drive. Do not use other format cartridges in your tape drive and do not use LTO cartridges in other format tape drives.

For optimum performance always use a data cartridge that matches the specification of your tape drive. A lower specification will have a lower transfer speed and may not support write activities; a higher specification will not support read or write.

6.3.3 Cartridge life

To avoid a backup failure due to worn media, replace the media (data cartridge) before either of the following occur:

● After one year of use

● After being used 1000 times

The lifespan of media varies depending on the environment (temperature, humidity, dust, etc.) and operating conditions of this product.

I IMPORTANT:

The data cartridge is a replaceable part. Worn media can cause problems such as magnetic tape surface damage, dirty magnetic head, many media errors, and so on.

Using Ultrium Media

6.3.4 Write protecting cartridges

V CAUTION!

Always remove the cartridge from the tape drive before you change the write protection.

If you want to protect the data on a cartridge from being altered or overwritten, you can write protect the cartridge.

● To write protect a cartridge, push the switch to the right to prevent any data

recording on the cartridge. Note the padlock on the tab that indicates that the cartridge is protected.

● To write enable a cartridge, push the switch to the left to allow data recording

on the cartridge. The location of the write-protect tab is illustrated by figure 6.

1. Write-protect tab

Figure 6: Write protecting a cartridge

38 LTO-6 Half-Height SAS Tape Drive

Using Ultrium Media

V CAUTION!

Write-protection will not protect your cartridges against magnets. Writeprotection will not prevent a cartridge being erased by bulk-erasure or degaussing. Do not bulk erase Ultrium format cartridges. This will destroy pre-recorded servo information and make the cartridge unusable.

6.3.5 Cleaning the tape drive

Perform magnetic head cleaning when the following occurs:

– Periodically (once every three months)

– When the drive requests to be cleaned.

You must use the Ultrium LTO Universal Cleaning cartridge with LTO tape drives, as other cleaning cartridges will not load and run.

To clean the tape drive:

1. Insert the Ultrium Universal Cleaning cartridge.

2. The drive will carry out its cleaning cycle and eject the cartridge on completion (which can take up to 2 minutes or more).

Each Ultrium universal cleaning cartridge cleaning cartridge can be used up to 50 times with Ultrium tape drives. If the cleaning cartridge is ejected immediately, it has expired.

6.3.6 Handling cartridges

● Do not touch the tape media.

● Do not open the drive door and touch the tape media.

● Do not attempt to clean the tape path or tape guides inside the cartridge.

● Do not leave cartridges in the drive. The tape loses tension in the power-off

state, which can lead to problems, particularly if the drive has been moved.

● Do not leave cartridges in excessively dry or humid conditions.

● Do not leave cartridges in direct sunlight or in places where magnetic fields

are present (for example, under telephones, next to monitors or near transformers).

LTO-6 Half-Height SAS Tape Drive 39

Using Ultrium Media

● Do not drop cartridges or handle them roughly.

● Stick labels onto the label area only.

● Do not bulk erase (or degauss) Ultrium format cartridges because this will

render them unusable.

● Attach the label at the location shown in the following figure.

I Always use the supplied label.

label po sition1

Figure 7: Attaching a label to media

6.3.7 Storage environment

To prevent condensation and for long life, the cartridge should only be stored as follows:

● Day-to-day storage (in plastic container): 16° C to 32° C (60° F to 90° F)

● Non-condensing relative humidity: 20% to 80% (storage)

● Wet bulb temperature should not exceed 26° C (79° F)

Tapes intended for long-term storage should be stored in the plastic containers, at temperatures between 5° C and 23° C (41° F and 73° F) and 20% to 60% relative humidity.
