Which operating systems are supported?
HP StorageWorks Ultrium drives can be connected to servers running under Windows®, Linux and
other major operating systems. Refer to the “Software Compatibility” section on our “HP StorageWorks
Tape Compatibility” web site (http://www.hp.com/go/connect/) 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:
Ultrium full-height SCSI Tape Drives 13

•Youwillneedaproperlyinstalledandconfigured SCSI host bus adapter (HBA) or a built-in
SCSI controller on your server and a suitably-rated SCSI cable. See also Why is the SCSI bus
type important?.
•ForoptimumperformancethedriveshouldbetheonlydeviceontheSCSIbus.
•Always terminate the SCSI bus. Ultrium internal and removable tape drives require terminators;
external drives are auto terminating, as long as they are on a dedicated SCSI bus or the last
device on a chain.
•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 ProLiant server with a Smart Array 6i RAID controller).
NOTE:
Always refer to http://www.hp.com/go/connect/ to ensure that you are connecting to a supported
HBA running the recommended firmware version.
Internal drives
The tape drive is installed into a spare, industry-standard, 5¼-inch, full-height drive bay in your server
(or into an HP Rack-Mount Option Kit) 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. For most servers we recommend that you use the terminated SCSI
ribbon cable supplied with the drive.
See also Installing an internal Ultrium tape drive.
External drives
Your tape drive is supplied with a 68-pin, wide, VHD-to-HD SCSI cable to attach to the host server.
See also Installing an external Ultrium tape drive.
Check the usage models on Usage models. This shows how the HP StorageWorks Ultrium tape drive can
be used in different system architectures.
Removable drives
The individual tape drives are connected to their host server via the high-density LVD/SE SCSI connectors
on the back of the tape array. They do not require any SCSI cables to plug into the tape array. However,
cabling and terminators are required to connect the tape array with the SCSI host. See also Installing a
removable Ultrium tape drive.
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. HP Ultrium 1840 and 960 drives support a burst
transfer rate of 320 MB/sec. HP Ultrium 460 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
busofasimilarorhigherspecification. This means that you need:
•An Ultra320 bus for HP Ultrium 1840 and 960 drives. An Ultra160 or Ultra320 SCSI bus for
HP ultrium 460 drives. If you attach the drive to a lower specification SCSI bus, it may 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.
14 Before you start

Table 2 Supported SCSI bus types
SCSI Bus Type Supported
Ultra320 LVD Yes. This is a recommended configuration for all Ultrium full-height tape drives.
Do not daisy chain Ultrium 1840 or Ultrium 960 tape drives because performance
will be degraded. Up to two Ultrium 460 tape drives may be daisy-chained.
Ultra160 LVD Yes. This is a recommended configuration for Ultrium 460 tape drives. It is an
acceptable configuration for Ultrium 960 and 1840 tape drives.
Up to two Ultrium 460 tape drives may be daisy-chained. Do not daisy-chain Ultrium
1840 and Ultrium 960 tape drives.
Ultra2 LVD Yes. This is acceptable for one Ultrium 460 drive per bus, but performance may
be impaired.
Do not use with Ultrium 1840 or 960 tape drives and do not daisy-chain Ultrium
460 tape drives.

Ultra narrow,
single-ended No. This will severely restrict performance and you will need a suitable cable or
adapter.
High Voltage

No. The drive will not work and you may damage the drive or controller
How can I check the SCSI bus type and SCSI ID?
For many operating systems, you can install and run HP Library & Tape Tools from either the
HP StorageWorks Tape CD-ROM or http://www.hp.com/support/tapetools to check your server’s
current SCSI configuration (see also Diagnostic tools ). This will provide information about the SCSI
bus and the SCSI IDs in use.
Ultrium full-height SCSI Tape Drives 15

Usage models
HP StorageWorks Ultrium tape drives can be used in a standalone or network environment. However,
they should always be directly attached to suitably-rated SCSI connector on the storage server.

Figure 2 Usage model
The following table shows the recommended usage models and Optimizing performance provides further
information about factors that can affect performance.
16 Before you start

Table 3 Recommended usage models
Direct Attach,
single storage server
Across the Network,
single storage server, multiple clients
Ultrium 1840 Recommended Not recommended
Ultrium 960 Recommended Requires careful design to utilize the drive’s performance
capabilities, even Gigabit Ethernet will limit performance
Ultrium 460 RecommendedRecommended, anything less than Gigabit Ethernet may
limit performance
A RAID disk subsystem is recommended for all usage models.
A single spindle disk will not be able to deliver good data throughput for an Ultrium 1840 or Ultrium 960
tape drive at any compression ratio. To maximize the capability of your Ultrium 1840 or 960 tape drive,
utilize aggregated disk sources (RAID) with multiple disk spindles.
A single spindle disk, particularly a fast disk such as a 15K RPM drive, will be sufficient for Ultrium 460
tape drives, but be aware of other factors that can affect performance—such as, compressibility of data,
disk fragmentation and the number of files. See also Optimizing performance.
You can use our free performance assessment tools, which are available standalone or integrated into HP
Library & Tape Tools, to check tape performance and test whether your disk subsystem can supply data
at the optimum transfer rate. You can also use these tools to calibrate your restore performance and
maximal tape performance with more compressible data.
Other usage models
Thetapedrivemayworkwithotherusagemodels,suchasnetworkattachstorage(NAS)andstorage
area networks (SAN), but HP does not currently provide technical support for installing and using
standalone Ultrium tape drives with these architectures. Similarly, connection to fibre channel may be
possible, if you purchase and install a fibre channel/SCSI bridge, but it is not currently a supported
option. Please check http://www.hp.com/go/connect for the latest supported configurations.
Using the HP StorageWorks Tape CD-ROM
The HP StorageWorks Tape CD-ROM is a central source of information about your tape drive with utilities
for getting the best performance from your tape drive.
Use the HP StorageWorks Tape CD-ROM to check installation, as described in this guide, and to verify
and troubleshoot performance after installation. It helps you to:
•Install your product, which includes access to drivers, and performance information and tools
•Learn about your product
•Register your product
•Buy media online
•Troubleshoot with HP Library & Tape Tools.

2Driversandbackupsoftware
Install drivers
NOTE:
The HP 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.
Installing on Windows
The driver available from Microsoft update is acceptable, but the HP driver provides better support for all
the features of your new tape drive.
The CD-ROM contains a driver install package for the following Microsoft Windows operating systems:
Windows Server 2000, Windows Server 2003 and Windows XP. If you prefer to use Windows Device
Manager to install the tape drivers manually, you will find them in the drivers directory on the CD-ROM.
NOTE:
We recommend that you use the installer package on the HP StorageWorks CD-ROM to install the drivers
BEFORE you connect the tape drive.
Updates to the drivers may be provided from time to time on the HP support web site
(http://www.hp.com/support). We recommend that these are installed after using the installer on the
CD-ROM.
Installing on UNIX
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, as described in the UNIX Configuration Guide on the CD-ROM.
Installing on IA64
IfyouareinstallingonanIA64system,suchasanHPIntegrityserver,checkhttp://www.hp.com/go/
connect for the latest information on the availability of backup application upgrades and drivers.
Upgrade backup software
It is important to check http://www.hp.com/go/connect for software compatibility and install any
recommended upgrades.
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, Symantec, Legato, Yosemite
and Computer Associates all provide suitable products. Further details about these and other products
that may be appropriate can be found on our connectivity web site.
1. Go to our connectivity web site: http://www.hp.com/go/connect and select tape backup.
2. Select software compatibility.
Ultrium full-height SCSI Tape Drives 19

3. Select your combination of operating system and tape drive model in the table. A list of supported
backup applications is displayed. This will also tell you whether your configuration is compatible
with HP One-Button Disaster Recovery, HP OBDR. (All HP StorageWorks Ultrium tape drives
support HP OBDR. However, you can only use this feature if your system configuration and backup
application also support it. See "Compatibility" on page 53.)
4. Make sure you have a backup application that supports HP StorageWorks Ultrium tape drives and
download any upgrades or patches, if required.
Enabling encryption
Your HP Ultrium 1840 tape drive includes hardware capable of performing data encryption while
writing and data decryption while reading, both at full speed. This is only possible with LTO-4 media.
See also refer to "Encryption" on page.
If you wish to make use of the encryption capability, you must enable this feature via the backup software
application. Refer to http://www.hp.com/go/connect to find out which applications support this
advanced data protection capability.
