1 Introduction

1.1 Overview

This chapter introduces your DLT VS160 Internal Drive, DLT

VS160 Tabletop Drive, and this Installation and Operations

Manual.

1.2 DLT VS160 Drive Overview

Your DLT VS160 Drive is a value-priced, high-reliability, high-

capacity linear streaming cartridge tape drive designed for use

on entry to midrange computing platforms. With a combination

of data compression and compaction, the DLT VS160 Drive

offers a formatted cartridge capacity of 80GB (160GB assuming

a 2:1 compression ratio) and a sustained user data transfer rate

of 8 MB/s (up to 16 MB/s with 2:1 compression). The capacity

you realize in practice depends on the data set, which affects

the actual compression ratio.

Your DLT VS160 Drive is built on a 5¼-inch, half-height form-

factor, using a ½-inch tape. Its design includes a four-channel

read/write head, Lempel-Ziv (DLZ) high-efficiency hardware

data compression, and tape-mark directory to achieve fast data

throughput and data access times.

1.2.1 Features

Your DLT VS160 Drive has the following features:

• Supported formats: ValuSmart 160 (read/write using

ValuSmart Media 1 cartridges), DLT1/VS80 (read only

using DLTtape™ IV cartridges)

• Uses ValuSmart Media 1 cartridges

• 5.25-inch half-height form-factor

• Formatted cartridge capacity of 80GB native, 160GB

compressed

• Sustained user data transfer rate of 8 MB/s native, up to 16

MB/s with compression*

• Requires a wide-ultra, Ultra2, Ultra160, or Ultra3, Low-

Voltage Differential (LVD) or Single-Ended (SE) SCSI bus

Introduction

1-2 DLT VS160 Installation and Operations Manual

* Assumes 2:1 compression ratio. The capacity and data

transfer rates realized in practice depend on the data set, which

determines the actual compression ratio.

1.2.2 Obtaining Drivers and Firmware

Upgrades

1.3 Scope of This Manual

This Installation and Operations Manual is intended to provide

all the information you need to install and use your DLT

VS160 Internal Drive or DLT VS160 Tabletop Drive.

DLT VS160 Installation and Operations Manual 2-1

2 Installing Your DLT VS160

Drive

2.1 Chapter Overview

This chapter explains how to configure and install your DLT

VS160 Tabletop Drive or DLT VS160 Internal Drive.

Configuration and installation are not difficult and require only

that you follow the steps and instructions presented in this

chapter.

2.2 Preparation

This section helps you prepare to install your DLT VS160

Tabletop Drive or DLT VS160 Internal Drive.

2.2.1 SCSI Requirements

Your DLT VS160 Drive (tabletop and internal) incorporates a

wide-ultra 160 Low-Voltage Differential (LVD) SCSI bus, but

may also be attached to a Single-Ended (SE) SCSI bus.

Make sure your SCSI host adapter or controller supports these

standards. If you connect the drive to an SE SCSI bus or if

there are SE devices attached to the same SCSI bus, the drive's

performance is limited to the maximum data transfer speed

and maximum cable lengths of the SE bus. The DLT VS160 is

not compatible with a standard differential (Diff) or High-

Voltage Differential (HVD) SCSI bus. If you attach the drive to

a narrow (50-pin) SCSI bus, you must use a customer-supplied

68-pin to 50-pin adapter that terminates the unused 18 pins.

These adapters are sometimes labeled "high-byte termination."

Make sure the total length of the SCSI bus does not exceed the

ANSI SCSI standard of 19 feet (6 meters) for an SE bus, 40 feet

(12 meters) for an LVD SCSI bus with multiple devices, or 82

feet (25 meters) for an LVD SCSI bus with a single device.

2.2.2 Before You Start

Installing your DLT VS160 Tabletop Drive requires no special

tools. You will need a ballpoint pen to change the SCSI ID

switch on the rear panel of the drive. Installing your DLT

VS160 Internal Drive requires only the usual tools needed to

Installing Your DLT VS160 Drive

2-2 DLT VS160 Installation and Operations Manual

install an internal drive in the computer you have chosen to

house the DLT VS160.

If you are installing a DLT VS160 Internal Drive, refer to page

2-9 for instructions.

2.3 Installing your DLT VS160

Tabletop Drive

This section contains step-by-step instructions for installing

your DLT VS160 Tabletop Drive.

2.3.1 Installation Overview

Installing your DLT VS160 Tabletop Drive is fast and easy

when you follow the instructions in this section in the order

presented. Installing your DLT VS160 Tabletop Drive consists

of the following steps, covered in the next few sections:

1. Unpack and check your drive for shipping damage.

2. Select a location near the server or workstation that is to be

the host for your DLT VS160 Tabletop Drive.

3. Set the SCSI ID for your DLT VS160 Tabletop Drive, if

necessary.

4. Shut down and turn off the server or workstation that is to

host your DLT VS160 Tabletop Drive. Remove the power

cable from the selected server or workstation. Turn off and

remove the power cables from all devices attached to the

selected server or workstation.

5. Install an LVD/SE SCSI host adapter in the server or

workstation that is to be the host for your drive, if

necessary.

6. Attach the SCSI cable to your DLT VS160 Tabletop Drive

and SCSI host adapter.

7. Install the terminator on your DLT VS160 Tabletop Drive if

it is the last or only device on the SCSI bus.

8. Attach the power cable to your DLT VS160 Tabletop Drive,

server or workstation, and all attached devices, plug in the

power cable to the nearest power outlet, and turn on all

devices.

9. Check your DLT VS160 Tabletop Drive to make sure it is

working properly.

Installing Your DLT VS160 Drive

DLT VS160 Installation and Operations Manual 2-3

2.3.2 Unpacking your Drive and Selecting a

Location

Before you begin, clear a desk or table so that you can unpack

your DLT VS160 Tabletop Drive. You also need to select a

location near the server or workstation that is to host your

drive.

Note: If the room in which you are working differs from the

temperature at which your DLT VS160 Tabletop Drive was

shipped or stored by 30° F (15° C) or more, let the drive

acclimate to the surrounding environment for at least 12 hours

before opening the shipping carton.

2.3.2.1 Unpacking your Drive

Before you do anything else, unpack and inspect your DLT

VS160 Tabletop Drive for shipping damage. If you notice any

damage, report it both to and the shipping company

immediately.

Note: Save the packing materials in case you need to move or

ship your drive in the future. You must ship your DLT VS160

Tabletop Drive in the original or equivalent packing materials

or your warranty may be invalidated.

2.3.2.2 Selecting a Location for your Drive

Select a location for your DLT VS160 Tabletop Drive that is

flat, sturdy, level, and close to the host server or workstation. A

desk or table-top is most suitable. Regardless of the location

you choose for your DLT VS160 Tabletop Drive, make sure the

environment is free from dust and excessive temperature and

humidity. See the DLT VS160 Product Specification manual for

acceptable operating temperature and humidity limits.

Be sure to follow these additional guidelines when selecting a

location for your DLT VS160 Tabletop Drive:

• Allow at least 6 inches (15.2 cm) behind the drive for proper

cooling.

• Avoid locations near printers or photocopy machines, both of

which produce paper fiber and other types of dust and

airborne contaminants.

• Do not place your drive on the floor.

Installing Your DLT VS160 Drive

2-4 DLT VS160 Installation and Operations Manual

• Avoid locations near generators, electric motors, audio

speakers, or other sources of magnetic fields. Magnetic

fields can adversely affect your drive and media.

2.3.3 Setting the SCSI ID

Regardless of the number of SCSI devices attached to the

server or workstation that is to be the host for your DLT VS160

Tabletop Drive, each device must have a unique SCSI ID.

Check the SCSI IDs on all other devices on the selected server

or workstation, including the SCSI host adapter, and select an

unused SCSI ID for your DLT VS160 Tabletop Drive. The

factory default SCSI ID is 5. If the drive’s factory default SCSI

ID is not being used by another device on the same SCSI bus,

you do not need to change the SCSI ID.

Figure 2-1: DLT VS160 Tabletop Drive Rear Panel Layout

Note: If you plan to attach the drive to a narrow (50-pin) SCSI

bus, you can only use IDs 0 through 7.

To set the SCSI ID on your DLT VS160 Tabletop Drive, use a

small screwdriver or ball-point pen to press the button above

the SCSI ID display to select the next lower SCSI ID. Press the

button below the SCSI ID display to select the next higher

SCSI ID. Each time you press one of these buttons, the SCSI ID

increases or decreases by one. Press the appropriate button

until the desired SCSI ID appears on the switch display.
