Before you start

The HP StorageWorks VS160 tape drive is a high-capacity, high-performance streaming tape

drive. It is installed into a spare drive bay in your server. Before starting to install your tape

drive, you should consider the following.

Which operating systems are supported?

HP StorageWorks VS160 drives can be connected to servers running under Windows®.

Refer to the “HP StorageWorks Tape Software Compatibility” topic on our World Wide Web

site (www.hp.com/go/connect) for more information about the operating system versions

that are supported.

.How do I the connect the tape drive to my server’s SCSI bus?

Your tape drive is attached to the SCSI bus of the host server via a spare connection on the

internal SCSI ribbon cable. You will need a properly installed and configured SCSI host bus

adapter (HBA) or a built-in SCSI controller on your server. For optimum performance your tape

drive should be connected to an Ultra 160 or Ultra 320 host bus adapter or SCSI controller

using a correctly terminated, LVDS-compatible ribbon cable with a spare 68-pin, high-density

(HD), wide SCSI connector.

For most servers we recommend that you use the terminated SCSI ribbon cable supplied with

the drive, see page 19. We also recommend that the drive is the only device on the SCSI bus.

Do not connect more than two tape drives per SCSI controller. Do not attach the drive to the

same SCSI bus as your disk drive or to a RAID controller, unless it is a ProLiant server with a

Smart Array 6i RAID controller.

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 StorageWorks VS160 tape

drives are high performance Ultra 160 SCSI devices with a maximum burst transfer speed of

160 MB/second. 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 Ultra 160 or Ultra 320 SCSI bus. Ultra 160 SCSI supports the maximum bus speed of

160 MB per second; Ultra 320 SCSI exceeds this.

•LVD-rated SCSI cabling and terminators. The LVD interface and cable supplied with the drive

enable the data to be transferred at the drive's maximum rate and provide a maximum cable

length of 12 meters.

If you attach the drive to a lower specification SCSI bus, it may still work, but data will not be

transferred as quickly. For example, on a single-ended (SE) Ultra 2 SCSI bus the maximum

burst transfer speed of the drive is 40 MB/second and the maximum cable length is restricted

to 3 meters. See also Table 1, “supported SCSI bus types,” on page 9.

Note The drives are not compatible with high voltage differential (HVD) SCSI devices.

How can I check the SCSI bus type?

We strongly recommend that you use HP Library & Tape Tools to check your server’s current

SCSI configuration. This will provide information about the SCSI bus and the SCSI IDs in use.

dltvs160_master.fm Page 3 Monday, November 22, 2004 10:30 AM

HP Library & Tape Tools is the recommended diagnostic and support tool for your HP tape

storage product. It is available as a free download from the HP web site and is supported on

nearly all major operating systems.

See www.hp.com/support/tapetools for compatibility information, updates and the

latest version of the tool.

What are the mounting requirements for the tape drive?

Mounting bay

You need one industry standard, 5¼-inch, half-height bay in which to install the

HP StorageWorks VS160 tape drive. Maximum power requirements are 2.1 A at 5 V and

2.7 A at 12 V.

Mounting hardware

Note M3 screws are supplied with the tape drive to secure it to the mounting bay.

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. Rail kits for a

number of industry-standard servers may be available. For more details refer to:

www.hp.com/go/connect.

Some servers use non-standard mounting rails and do not include spares. If this is the case

with your system, you will have to order these accessories from the server manufacturer before

you can install the tape drive.

Air flow requirements

The server must provide forced cooling and be capable of drawing 3 cfm (0.08 m3/minute

or 5.1 m3/hour) of air through the tape drive at 40oC ambient operation. Always operate

the tape drive within an ambient air temperature of no more than 40oC.

It is important to keep the cooling holes in the rear and the grill in the front of the tape drive

clear of any obstructions that may hinder the air flow and to ensure that all fans in your server

are in place and operational. Make sure that empty bays have the appropriate blanking

plates installed so that airflow is maintained.

Do I need additional items for installation?

• You may need mounting hardware. See “What are the mounting requirements for the tape

drive?” above.

• If you do not have a spare, suitably rated SCSI connector on your server, a new HBA (also

known as a SCSI card) will be required. The SCSI bus rating should match or be higher than

the SCSI rating of your tape drive. See Table 1, “supported SCSI bus types,” on page 9 for

recommended HBAs. For specific details relevant to your server model please refer to

www.hp.com/go/connect. You will need to purchase and install the new HBA into an

unused, 64-bit PCI expansion slot within your server before installing your tape drive. (The

kit can also be installed in a 32-bit PCI expansion slot, but performance may be degraded.)

Refer to our World Wide Web site for recommended products, configurations and ordering

information: www.hp.com/go/connect or www.hp.com/support/dlt.

Backup software and drivers

Backup software

For optimum performance it is important to use a backup application that is appropriate for

your system’s configuration. In a direct attach environment, 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, Veritas, 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.

1Go to our connectivity web site: www.hp.com/go/connect and select tape backup.

2Select software compatibility.

3Select your combination of operating system and tape drive model in the table. A list of

supported backup applications is displayed.

4Make sure you have a backup application that supports HP StorageWorks VS160 tape drives

and download any upgrades or patches, if required.

Drivers

Windows users

After you connect the tape drive, download the HP driver from our web site: www.hp.com/

support, see “Step 8: Verify installation” on page 23.

Refer to the accompanying README file for specific installation instructions for Windows

2000, Windows XP and Windows Server 2003 drivers.

Note: We recommend that you install drivers from the web rather than the Windows

Hardware Installation Wizard, because the HP drivers fully support the performance of your

tape drive.

Step 1: Check the SCSI connection

Use the following questions to help you check your SCSI connection. As long as you have a

spare drive bay in your server you should have a spare connection on the internal SCSI bus.

You need to ensure it is the correct SCSI bus type. Windows users can use HP Library & Tape

Tools to check the SCSI bus type, see page 30. If you answer ‘Yes’ to all these questions, you

are ready to install your tape drive. If you answer ‘No’, you will probably need to purchase

and install additional items. For product details, go to www.hp.com/go/connect.

table 1: supported SCSI bus types

SCSI Bus Type Transfer Speed Supported

Ultra 160 LVD Up to 160 MB/s Yes. This is a recommended configuration.

Ultra 320 LVD Up to 320 MB/s Yes. This is a recommended configuration.

Ultra 2 LVD Up to 80 MB/s Yes, but this is not recommended

Ultra single-ended,

wide

Up to 40 MB/s Yes, but this is not recommended as it will restrict

performance. Do not connect to a narrow SCSI bus.

High Voltage

Differential

Up to 40 MB/s No. The drive will not work and you may damage

the drive or controller

1Is there a spare SCSI port on

the server’s internal SCSI

bus?

3Will the drive be the only

device on the bus? This is the

recommended configuration.

Do not connect to a RAID

controller channel.

2Are the SCSI ribbon cable

and HBA card rated at Ultra

160 or higher? (Make sure

the ribbon cable is

terminated. See page 19.)

Performance may be impaired.

Consider installing (if you have a spare

PCI slot) or replacing your card with an

Ultra 320 HBA. Make sure the last

device on the bus is terminated.

See table below. If the SCSI bus differs

from the recommended specification for

the drive, performance of either the

drive or the bus may be impaired.

Consider replacing your card with one

of the recommended HBAs.

Purchase and install one of the

recommended HBAs into an unused

64-bit PCI expansion slot. See table

below.
