Chapter 1
1Introduction
This chapter provides an introductory overview of the Quantum LTO-4
Half-Height Tape Drive. Topics include:
•Overview
•Drive Models
•Features
Overview
The Quantum LTO-4 Half-Height Tape Drive is a high-performance 16-
channel tape drive that complies with the LTO interchange specifications.
The drive is suited for mid-range to high-end servers, mainframe
systems, and tape library automation systems.
The LTO-4 Half-Height Tape Drive uses Ultrium data cartridges. Its
capacity is maximized using intelligent data compression. The drive has a
native capacity of 800 Gbytes (1,600 Gbytes assuming 2:1 data
compression).

Chapter 1 Introduction
Drive Models
LTO-4 Half-Height Tape Drive User’s Guide 2
The LTO-4 Half-Height Tape Drive has a 5¼-inch half-height form factor
with automatic electromechanical cartridge soft load. It is available in two
models:
• Internal
• Tabletop
Drive Models
Internal 1The internal model (see figure 1) is a 5¼-inch drive that you can install
inside the drive bay of a:
• Computer workstation or server system
• Quantum rackmount drive enclosure
Tabletop 1The tabletop model is a 5¼-inch drive that is already mounted inside a
stand-alone external drive enclosure with a built-in power supply.

Handling Precautions
and Installation
Guidelines 2
Always observe the following precautions and guidelines when handling
and installing LTO-4 Half-Height Tape Drives:
• Internal, at all times
• Tabletop, when removed from its free-standing enclosure
Handling Precautions • Internal drives have exposed
components that are sensitive to static
electricity. To reduce the possibility of
damage from static discharge, the
drives are packaged in a protective
antistatic bag. Do not remove the drive
from the antistatic bag until you are
ready to install it.
• Wear an ESD-preventive grounding
wrist strap or observe similar ESD
precautions when working with the
drive. Be sure the wrist strap makes
good skin contact. Do not remove the
wrist strap until you finish working
with the drive.
Also, avoid contact between the drive,
other equipment, and clothing. The
wrist strap only protects the equipment
from ESD voltages on the body; ESD
voltages on clothing can still cause
damage.
• Before removing the drive from the
antistatic bag, touch a grounded metal
surface to discharge any static
electricity buildup from your body.

Preinstallation
Requirements 2Before installing the LTO-4 Half-Height Tape Drive, make sure you have:
• A serial SCSI host bus adapter (HBA) installed and properly
configured in the host computer
• Interface components, either:
• 7-pin 1x SATA style interface cable for an internal drive
• 26-pin SFF-8088 mini-SAS style interface cable for a tabletop
drive
• Backup application software that supports the tape drive. For a list of
the backup software applications that have been tested with the LTO-
4 Half-Height Tape Drive, please visit our website at:
www.quantum.com/support
Unpacking and
Inspecting the Drive 2Although each LTO-4 Half-Height Tape Drive is inspected and carefully
packaged at the factory, damage can occur:
• In shipment
• When being unpacked
Handling Precautions
(continued)
• Handle the drive by its sides rather
than by the top cover to reduce the risk
of dropping the drive or damaging it
during installation.
• Either lay the drive on a nonconductive
surface or put it back inside the
protective antistatic bag to reduce the
chance of damage from static discharge
Installation Guidelines Due to the high speed of the LTO-4 Half-
Height Tape Drive, do not connect more
than one LTO-4 drive to the same channel
on a host SCSI adapter.
