CHAPTER 1 Introduction
1.1 Purpose and Scope
The purpose of this design and integration guide is to provide detailed information
that may be helpful to refer to as you integrate the SDLT 220 and SDLT 320
cartridge tape systems into larger systems. The SDLT 220 and SDLT 320 cartridge
tape systems, subsequently referred to in this document as SDLT 220/320, have
many characteristics in common, enabling both sets of information to be presented
in a single document.
This guide is intended mainly for customers who will be integrating the SDL T
drive into their products. Technical knowledge on the part of the user is assumed.
NOTE: Except where clearly noted, the information in this
document applies to both models of the tape drive.

1.8 Tandberg Diagnostics Tools
Tandberg frequently provides new and updated tools to use with its tape drives. For
For example:
All tools are available on Tandberg’s web site, http://www.tandberg.com. Follow
the path Service and Support -> DLTtape Drivers and Software and look at the list
to see what is available.
SDLT Update Allows you to update a drive’s firmware
(using the SCSI bus), or to create a code
update (CUP/FUP) tape for an SDLT drive.
GS Link Allows you to quickly diagnose the integrity
of the drive using an infrared (wireless)
communication connector located on the front
panel of the tape drive.
QS Link A cross-platform tool that allows you to
perform functions such as updating firmware,
editing mode pages, viewing log pages,
viewing and editing EEPROM parameters.

2.1 Product Description
Figure 2-1. SDLT 220/320 Drive System
Internal drive External drive
The Tandberg Super DLTtape™ System is a highly scalable platform designed
for multiple product generations. It is a follow-on to the DLTtape product family,
which is the industry standard for mid-range UNIX and NT system backup and
archive applications. The SDLT tape system consists of the drive and the tape
cartridge; the system is available in either a built-in (internal) model or a tabletop
model.

2.2 SDLT Product Features
SDLT tape drives offer the following product features:
• A streaming tape drive that uses half-inch wide Digital Linear Tape (DLT)
media.
• Standard 5.25-inch full-height form factor to simplify integration into system
and tape library solutions.
• The SDLT architecture builds on the DLT legacy by offering backward
compatibility: data backed up today using the DLT 8000, DLT 7000, DLT
4000, and DLT 1/VS80 (Benchmark) systems will be retrievable in the f uture
using SDLT-based systems with DLT IV type media .
• Global Storage Link (GS Link) — An infrared (wireless) interface that
provides a wireless remote testing base allowing customers and integrators to
access system diagnostic information from the front of the tape system.
• When needed, the SDLT 320 can be operated in a mode that is completely
compatible with that of the SDLT 220.
• Handle-free load and unload feature to increase ease of use.
• One of three possible SCSI implementations ; these three imple menta tions are
listed in “SCSI Interface Type” on page 6-1.
CHAPTER 2: Ge n eral Drive Spe ci fications
2.2.1 SDLT 220/320 Lib ra ry Tape Drive Inter f ace
The library tape drive interface (for SDLT drives) is an RS-422 serial port set to
9600 baud, 8 bits per character, no parity, and 2 stop bits. All data sent to or from
the library tape drive interface consists of bit-wise encoded hex values.
2.2.2 SDLT 220/320 Front Panel LEDs

2.5 Reliability
Tandberg Data and its employees and suppliers are committed to providing quality
products. The SDLT tape drive system is a very reliable electromechanical device.
2.5.1 Positive Engagement Tape Leader Buckling
Mechanism
This buckling mechanism is responsible for engaging the tape leaders upon
cartridge load and disengaging them upon cartridge unload. The SDLT tape
buckling mechanism has been designed to work with the new leaders of the SDLT
tape drive design as well as the leaders of the previous DLT drive design, allowing
backward-read compatibility of DLTtape IV cartridges in the SDLT tape system.
Component level tests of buckle arm components have shown at least 250,000
cycles on an SDLT drive without failure, breakage, or binding; this includes the
take-up leader, the supply leader, and the media itself.
2.5.2 MTBF
Mean time between failures (MTBF) for the overall tape system is projected to be
250,000 hours. Head life is a minimum of 30,000 tape motion hours and an
average of 50,000 tape motion hours. Media durability is 1,000,000 passes.
NOTE: Tandberg Data does not warrant that predicted
MTBF is representative of any particula r unit ins ta lled for
customer use. Actual figures vary from unit to unit.
CHAPTER 2: G en era l Dr iv e S pe ci fic a t io ns
2.5. 3 Load and Unl o ad Cycles
Load and unload cycles are rated at 15,000 for the cartridge itself. Table 2-3 shows
the number of load and unload cycles and tape insertions an SDLT drive can
perform before it needs to be replaced.
2.5.4 Data Integrity
SDLT data transfer errors are extremely rare ; data integrity for the overall tape
system is shown in Table 2-4.
