Before you start

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

drive. 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 use the tape drive with my system?

Check the usage models on page 7. This shows how the HP StorageWorks VS160 tape drive

can be used in different system configurations; direct attach and network attach.

How do I connect the drive to my server?

Your tape drive is supplied with a 68-pin, wide, VHDCI-to-HD SCSI cable to attach to the host

server. You will need a properly installed and configured SCSI host bus adapter (HBA) or a

built-in SCSI controller on your server with a spare LVDS SCSI port with a 68-pin, very high

density (VHDCI), wide SCSI connector.

For optimum performance your tape drive should only be connected to an Ultra 160 or Ultra

320 host bus adapter or SCSI controller and it should be 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 RAID controller, unless it is a ProLiant server with a Smart Array

6i RAID controller.

See also Table 1, “supported SCSI bus types,” on page 11.

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 enables the data to

be transferred at the drive's maximum rate and provides 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 11.

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

dltvs160_master.fm Page 3 Monday, November 22, 2004 10:33 AM

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.

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.

Do I need additional items for installation?

• If you do not have a VHDCI, wide SCSI connector on your server, you will need to purchase

and install a VHDCI-to-HD adapter or use an HD-to-HD cable instead of the supplied cable.

• If the tape drive is not the only or last device on the SCSI bus, you must terminate the bus

with a multimode terminator. If the tape drive is the only or last device on the bus, then the

tape drive enclosure provides active termination and you do not need to purchase a

separate terminator.

• 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 11

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 5: Verify installation” on page 19.

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.

Usage models

The tape drive (B) can be used in a standalone or network environment. In a network

environment, anything less than Gigabit Ethernet may limit performance. The tape drive

should always be directly attached to a VHDCI SCSI connector on the storage server (A), as

shown in Figure 1.

A RAID disk subsystem is recommended. A single disk, particularly a fast disk such as a 15K

RPM drive, will also be sufficient, but be aware of other factors that can affect performance—

such as, compressibility of data, disk fragmentation and the number of files. 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. See also

“Optimizing performance” on page 27.

Other models

The tape drive may work with other usage models, such as network attach storage (NAS) and

storage area networks (SAN), but HP does not currently provide technical support for

installing and using standalone DLT VS160 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 www.hp.com/go/connect for the latest supported configurations.
