1 Features and overview
The Autoloader provides a compact, high-capacity, low-cost solution for simple, unattended data
backup. This unique design houses up to eight tape cartridges in a compact 1U form factor with
easy access to tape cartridges via two removable magazines and a configurable mailslot. Each
magazine can hold up to four cartridges.
The Autoloader can support Ultrium half-height tape drives. To see the tape drives currently available
for the 1/8 G2 Tape Autoloader, see the MSL QuickSpecs at www.hp.com/go/tape. For a list of
all supported configurations, go to www.hp.com/go/ebs.
The Autoloader is compatible with most operating systems and environments that support the SAS,
parallel SCSI, or Fibre Channel interfaces. However, the Autoloader requires either direct support
from the operating system or a compatible backup application to take full advantage of its many
features. To verify compatibility, go to www.hp.com/go/ebs.
The Autoloader uses the interface types described in Table 1 (page 8). The parallel SCSI Tape
Autoloader uses a single SCSI ID with two logical unit numbers (LUNs) — one for the tape drive
and the other for the robotic.

Autoloader options
HP StorageWorks 1/8 G2 & MSL Encryption Kit
The Encryption Kit provides secure generation and storage of encryption keys. The Encryption Kit
may be used with any HP StorageWorks 1/8 G2 Tape Autoloader or the MSL2024, MSL4048,
MSL8048 and MSL8096 Tape Library with at least one LTO-4 or later generation tape drive. The
Encryption Kit cannot be used with the MSL6000.
The Encryption Kit includes two USB key server tokens. One key server token is available for use
as backup for the other.
To use the Encryption Kit, a key server token is inserted in the USB port on the back of the
Autoloader, and encryption is enabled and configured from the RMI.
The Encryption Kit supports your manual security policies and procedures by providing secure
storage for encryption keys. Access to the key server tokens and their backup files is protected with
user-specified passwords. You will need to create processes to protect the tokens and secure the
passwords.
IMPORTANT: When encryption is enabled with the Encryption Kit, the Autoloader will not use
encryption keys from other sources, such as a key management system or application software.
Disable encryption in applications writing to the Autoloader when encryption is enabled with the
Encryption Kit. Applications that attempt to control encryption while encryption is enabled with the
Encryption Kit will not be able to do so, which can cause backups or other write operations to fail.
Command View TL TapeAssure
HP StorageWorks Command View TL software provides a browser-based GUI for remote
management and monitoring of most HP libraries through a LAN. With Command View TL, you
can view and analyze the performance and health of the LTO-4 and LTO-5 tape drives and media
in multiple HP MSL2024, MSL4048, MSL8048, and MSL8096 Tape Libraries and 1/8 G2 Tape
Autoloader options 9

Autoloaders at the same time. In addition, the information shown in TapeAssure is more extensive
than that shown in the RMI.
Command View TL software is installed on a management station. The management station can
also be used to manage HP StorageWorks EML and ESL Tape Libraries. For best performance, the
management station should be in the same physical location and on the same IP subnet as the
Autoloader. Command View TL software is available for download without charge from the HP
website at http://www.hp.com/support/cvtl.
For information on installing and using Command View TL, see the HP StorageWorks Interface
Manager and Command View TL User Guide, available from the HP website at http://
www.hp.com/support/cvtl.
Command View TL support is included in all Autoloader firmware that supports LTO-5 tape drives.
To find and download the most up-to-date firmware revision, visit the HP website at http://
www.hp.com/support.
Interface specifications and requirements for parallel SCSI drives
The parallel SCSI Autoloaders use the SCSI interface types described in Table 6 (page 10). The
Autoloaders use a separate SCSI ID for each tape drive, with dual LUNs on the master drive's SCSI
ID to control the tape drive (LUN 0) and Autoloader robotic (LUN 1). HP recommends that each
Ultrium tape drive be put on its own bus when possible.
Table 6 Parallel SCSI interface types
SCSI InterfaceLTO generation
Ultra 160 SCSI LVD/SELTO-2
Ultra 320 SCSI LVDLTO-3, LTO-4
The parallel SCSI Autoloader incorporates a wide SCSI-2 or SCSI-3 Low-Voltage Differential (LVD)
SCSI bus. Make sure your SCSI host adapter or controller supports these standards.
IMPORTANT: The Tape Autoloader is NOT compatible with a high-voltage differential (HVD)
SCSI bus. Do not put the Autoloader on a narrow (50-pin) parallel SCSI bus because doing so will
severely degrade performance.
Parallel SCSI host bus adapters (HBAs)
For optimum performance, place the Autoloader on its own SCSI bus with a host bus adapter that
can transfer data as fast as the Autoloader can read and write. The HBA must also be supported
by your operating system. Refer to the EBS matrix at http://www.hp.com/go/ebs for current HBA
compatibility information.
•For LTO-3 or LTO-4 tape drives, use an Ultra 320 HBA.
•For LTO-2 tape drives, use an Ultra 320 or Ultra 160 HBA.
IMPORTANT: Do not connect an Ultrium tape drive to an SE SCSI bus, as it severely degrades
Autoloader performance. A single-ended SCSI host bus adapter severely degrades Autoloader
performance and limits cable length. Also, if any SE devices are on the SCSI bus, all of the devices
on the bus slow down to SE speed, severely degrading performance.
Multiple LUN support
The Autoloader uses a single SCSI ID and two logical unit numbers (LUN). LUN 0 controls the tape
drive and LUN 1 controls the robotic. The Autoloader requires an HBA that supports multiple LUNs.
If multiple LUN support is not enabled, the host computer cannot scan beyond LUN 0 to discover
the Autoloader. It just sees the tape drive.
10 Features and overview

Parallel SCSI HP Smart Array controllers, RAID controllers, and most on-board HBAs do not support
multiple LUNs. Refer to the EBS matrix at http://www.hp.com/go/ebs for current HBA compatibility
information.
IMPORTANT: The Autoloader requires an HBA that supports multiple LUNs, which is also called
“LUN scanning.”
Interface specifications and requirements for Fibre Channel drives
The Fibre Channel tape drive can be connected directly to the server with a host bus adapter (HBA)
or through a storage area network (SAN).
Table 7 FC drive interface speeds
Supported speedsLTO generation
2 Gb, 4 Gb, 8 GbLTO-5
If you plan to connect the Autoloader directly to the server, you will need a 2 Gb, 4 Gb, or 8 Gb
Fibre Channel HBA. An 8 Gb HBA is recommended for LTO-5 tape drives for optimal performance.
Check the EBS matrix at www.hp. com/go/ebs to verify that your HBA is supported on your server
and qualified for the Autoloader.
In a SAN installation, all switches between the host and the Autoloader must be of the appropriate
type. For example, a 2 Gb switch in the path may result in performance degradation when backing
up highly compressible data to a 4 Gb tape drive. Configure zoning so only the backup servers
may access the Autoloader.
Interface specifications and requirements for SAS drives
The server must have an HP or third party SAS host bus adapter with an external connector.
Table 8 SAS drive interface speeds
Supported speedsLTO generation
1.5 Gb, 3 GbLTO-3, LTO-4
1.5 Gb, 3 Gb, 6 GbLTO-5
The device uses multiple LUNs to communicate with the Autoloader. Most SAS RAID controllers do
not support multiple LUNs. Check the EBS matrix at www.hp.com/go/ebs to find a SAS HBA that
is supported on your server and qualified with the Autoloader.
Most SAS HBA ports provide four SAS channels. The Autoloader only uses one channel. The HP
cable supplied with the Autoloader has one connector on each end, using only one of the four
channels. To use the other channels, you can purchase a SAS fanout cable, which will connect up
to four SAS tape drives to a single HBA port. When using a different cable, verify that the mini-SAS
connector for the tape drive end is keyed for location 4.
CAUTION: High quality SAS cables rated at the transfer rate of the SAS components are required.
Always verify that the SAS cable you are using is rated for the data transfer speed of the interface
of your components. SAS cables described as "equalized" may not support 6 Gb/s data rates
and should not be used with LTO-5 tape drives unless these cables are verified for 6 Gb/s data
rates. For optimum performance, only use HP cables of the length specified as qualified for your
products.
See About SAS (page 19) for more information about SAS.
Interface specifications and requirements for Fibre Channel drives 11

LTO-4 and later generation tape drives and encryption
The LTO-4 and later generation tape drives include hardware capable of encrypting data while
writing data, and decrypting data when reading. Hardware encryption can be used with or without
compression while maintaining the full speed and capacity of the tape drive and media.
Encryption is the process of changing data into a form that cannot be read until it is deciphered
with the key used to encrypt the data, protecting the data from unauthorized access and use. LTO
tape drives use the 256-bit version of the industry-standard AES encrypting algorithm to protect
your data.
To make use of this feature you need:
•The HP StorageWorks 1/8 G2 & MSL Encryption Kit or a backup application that supports
hardware encryption.
•LTO-4 or LTO-5 media; no encryption will be performed when writing LTO-3 and earlier
generations of tape.

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.
Using the Encryption Kit
The Encryption Kit includes two USB key server tokens. One key server token is available for use
as a backup for the other. Alternatively, you can save the encryption keys to a file and store that
file in a safe location.
To use the Encryption Kit, a key server token is inserted in the USB port on the back of the
Autoloader, and encryption is enabled and configured from the RMI.
The Encryption Kit supports your manual security policies and procedures by providing secure
storage for encryption keys. Access to the key server tokens and their backup files is protected with
user-specified passwords. You will need to create processes to protect the tokens and secure the
passwords.
IMPORTANT: When encryption is enabled with the Encryption Kit, the Autoloader will not use
encryption keys from other sources, such as a key management system or application software.
Disable encryption in applications writing to the Autoloader when encryption is enabled with the
Encryption Kit. Applications that attempt to control encryption while encryption is enabled with the
Encryption Kit will not be able to do so, which can cause backups or other write operations to fail.
See the Encryption Kit user guide for additional information on using the Encryption Kit.
12 Features and overview

Using application-managed 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. See http://www.hp.com/go/ebs for
an up-to-date list of other suitable backup software.
NOTE: The Autoloader can only obtain encryption keys from one source. Using the Encryption
Kit will prevent application-managed encryption.
Encryption is primarily designed to protect the media once it is offline and to prevent it being
accessed from another machine. You will be able to read and append the encrypted media without
being prompted for a key as long as it is being accessed by the machine and application that first
encrypted it.
There are two main instances when you will need to know the key:
•If you try to import the media to another machine or another instance of the backup application
•If you are recovering your system after a disaster
NOTE: 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.
If you are unable to supply the key when requested to do so, neither you nor HP 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.
CAUTION: 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.
For more information about AES encryption, encryption keys, and using hardware encryption with
your HP Ultrium tape drive, see the White Papers on http://h18006.www1.hp.com/storage/
tapewhitepapers.html.
For detailed instructions about enabling encryption please refer to the documentation supplied with
your backup application or with the HP StorageWorks 1/8 G2 and MSL Encryption Kit. This will
also highlight any default states, for example when copying tapes, that may need changing if
using encrypted tapes.

Preparing the host
IMPORTANT: Use proper procedures to prevent electrostatic discharge (ESD) (see Appendix:
Electrostatic discharge (page 158)). Use wrist-grounding straps and anti-static mats when handling
internal components.
Follow these general steps:
•If the host server is connected to a network, check with the system administrator before powering
off the computer.
•For parallel SCSI Autoloaders, install a parallel SCSI host bus adapter (HBA) that supports
multiple LUNs. Refer to the manuals for the host computer and the HBA for installation
information. See Parallel SCSI host bus adapters (HBAs) (page 10) for HBA requirements.
•For SAS Autoloaders, install a SAS host bus adapter (HBA) with an external SAS connector
that supports multiple LUNs. Refer to the manuals for the host computer and the HBA for
installation information. See Planning the SAS configuration (page 19) for configuration
requirements.
•For Fibre Channel Tape Autoloaders, install an FC host bus adapter (HBA) or verify that you
have sufficient ports available on a compatible Fibre Channel switch. See Planning the Fibre
Channel configuration (page 20) for configuration requirements.
Preparing the host 17

•Install application software and compatible drivers on the host computer. See the application
software manuals for installation and configuration information.
•Make sure multiple LUN support is enabled on the host computer. See Multiple LUN
support (page 10).
Planning the parallel SCSI configuration
If the host computer will have multiple parallel SCSI devices, you must decide how they will be
configured into one or more parallel SCSI busses.
About parallel SCSI busses
A parallel SCSI bus consists of the host bus adapter (HBA), the parallel SCSI devices, the parallel
SCSI cables, and the terminators. The HBA and devices are connected in a chain, with each device
connected to the next. The last device must have a SCSI terminator. Each device in the chain must
have a unique SCSI address (SCSI ID).
Complex devices, such as the Autoloader, assign sub-addresses, called logical unit numbers (LUNs),
to different parts of the device. The HBA and operating system must support multiple LUNs, also
called LUN scanning, for the application software to operate the Autoloader. HP Smart Array
controllers, most third-party RAID controllers, and many on-board SCSI controllers do not support
multiple LUNs.
An HBA might have one or two channels, with each channel supporting one parallel SCSI bus.
Check to see how many channels the HBA has and what devices are already connected to the
HBA. Some devices, such as parallel SCSI disk drives, could be inside the server.
The devices on a parallel SCSI bus share bandwidth so be careful about which devices you put
together on a bus. Also, putting a single-ended (SE) SCSI device on the bus will slow all of the
devices on the bus down to SE speed. Check each device's interface specifications to see what
kind of parallel SCSI interface it has.
Optimizing throughput
If possible, put the Autoloader on its own parallel SCSI bus. This will give you the best performance
and easiest installation.
If a tape drive must share a parallel SCSI bus with one or more other devices, follow these guidelines
to plan your parallel SCSI busses for the highest performance:
•Do not put a tape drive on the same parallel SCSI bus as a disk drive because the system and
backup performance will be slow when data is written from the hard drive to tape or from
tape to the hard drive.
•Do not put a tape drive on the same parallel SCSI bus as a disk array because the disk and
the tape drive performance will be affected, most RAID controllers do not support multiple
LUNs, and the data on the disk array could become corrupted.
•Avoid putting an SE SCSI device on the same bus as a tape drive because the SE device will
slow the tape drive to SE speed and reduce the allowable cable length.
SCSI addresses
Verify that each device on the bus has a unique SCSI address (SCSI ID). The pre-configured SCSI
address for the Autoloader is 4. If 4 is already used for another device, you will need to change
the SCSI address of the Autoloader during the installation process.
NOTE: The HBA also has a SCSI address, which is typically 7.
NOTE: Use the HP Library & Tape Tools to check your server's parallel SCSI configuration. The
HP Library & Tape Tools utility is available without cost at www.hp.com/support/TapeTools.
18 Installing the Tape Autoloader

Planning the SAS configuration
The key steps in planning the SAS configuration are obtaining a suitable HBA and cable.
The Autoloader uses two SCSI logical unit numbers (LUNs) and requires an HBA with multiple LUN
support. Most HP SAS RAID controllers support Tape Libraries; many non-HP SAS RAID controllers
to not support Tape Libraries. To verify the specifications of your HBA or find a list of compatible
HBAs, review the compatibility matrix on the Enterprise Backup Solutions web site at: http://
www.hp.com/go/ebs.
CAUTION: Do not connect the Autoloader to a SAS RAID controller unless the EBS matrix shows
that the controller is qualified with the Autoloader. The server might not be able to boot when the
Autoloader is connected to a non-supported SAS RAID controller.
About SAS
Serial Attached SCSI (SAS) is a computer bus technology mainly used to transfer data to and from
storage devices, including disk drives and tape drives. SAS-1 (LTO-4) is designed to transfer data
at 3 Gb/sec, which is comparable to the speed attained by Ultra320 SCSI. SAS-2 (LTO-5) is
designed to transfer data at 6 Gb/sec.
SAS cables and connectors
SAS uses serial connections, with a direct connection between the host server and each of the
storage devices. This eliminates the need to configure SCSI busses and assign SCSI IDs, as is
required for parallel SCSI devices.
Most SAS HBA ports have four SAS channels. A tape drive uses one channel, so each HBA port
can support up to four tape drives. You can use a cable with one connector on each end, but only
one channel will be used. To use the other channels, you can purchase a SAS fanout cable with
a connector for each tape drive, as shown in Example SAS fanout cable (page 19).
Figure 8 Example SAS fanout cable
The Autoloader has a mini-SAS connector on the tape drive. The connector is keyed in location 4,
which is the standard location for end devices. If you use a cable other than the one supplied with
the product, verify that it is keyed in location 4.
CAUTION: Mini-SAS connectors are keyed. Do not force a SAS cable's mini-SAS connector into
the tape drive mini-SAS connector because it might be keyed differently.
Planning the SAS configuration 19

SAS signal rates require clean connections and a minimum number of connections between the
HBA and the device. Do not use adapters or converters between the HBA and the device. HP
recommends a maximum SAS cable length of six meters.
CAUTION: High quality SAS cables rated at the transfer rate of the SAS components are required.
Always verify that the SAS cable you are using is rated for the data transfer speed of the interface
of your components. SAS cables described as "equalized" may not support 6 Gb/s data rates
and should not be used with LTO-5 tape drives unless these cables are verified for 6 Gb/s data
rates. For optimum performance, only use HP cables of the length specified as qualified for your
products.
World Wide identifiers
A SAS tape drive is identified by a unique identifier called a World Wide Name (WWN) or World
Wide Identifier (WWID). The Autoloader assigns the World Wide identifier to the drive bay. When
a tape drive is replaced, the World Wide identifier is re-assigned to the new tape drive.
Planning the Fibre Channel configuration
You can connect the Autoloader directly to the server with a host bus adapter (HBA) or indirectly
through a storage area network (SAN) with a switch.
Direct connection
If you plan to connect the Autoloader directly to the server, you will need a 2 Gb, 4 Gb, or 8 Gb
Fibre Channel HBA. An 8 Gb HBA is recommended for LTO-5 tape drives for optimal performance.
Check the EBS matrix at www.hp. com/go/ebs to verify that your HBA is supported on your server
and qualified for the Autoloader.
A server that uses Fibre Channel disks needs at least two FC ports. Using the same port for disk
and tape access will cause performance degradation.
SAN connection
All switches between the host and the Autoloader must be of the appropriate type. A 2 Gb switch
in the path may result in performance degradation when backing up highly compressible data.
Configure zoning on the Fibre switch so only the backup servers may access the Autoloader. See
the switch manual for information on zoning.
Choosing a location
If you plan to mount the device in a rack, select an open rack location, ideally near the center of
the rack or higher, with access to the host server and a power outlet. You may also set the
Autoloader on a shelf in the rack. In this case you must attach the feet during the installation process.
If you plan to set the Autoloader on a table, select a level area large enough to support both edges
of the Autoloader with access to the host server and a power outlet.
Choose a location that meets the criteria shown in Location criteria (page 20):
Table 10 Location criteria
DefinitionCriteria
The Autoloader can only be placed on a flat surface if the support feet have been properly
applied or the Autoloader is mounted in the optional tabletop conversion cover. Select a
Tabletop requirements
location that is flat, sturdy, and close to the host server. Ensure that all of the feet on the
Autoloader or tabletop conversion cover will be supported.
Do not place the device on the floor or other carpeted surface.
