02-17-94: Dick Desjardins asked me to work out a convenient way to establish the correct title placement for
the StorageWorks covers, which will have a diecut aperture in the cover, with the title showing through.
Dick says that Al Mayer’s design specs call for the title to be set in 42-point Palatino. At the same time,
however, the design specs provided by the printing department indicate the text is to fit in a space that is
designed to be 2.17” high by 5.33” wide, with the bottom edge being 6.5” from the bottom of the page and the
left edge being 2.25” from the left edge of the page, with the aperture having slightly rounded corners.
The obvious approach should be to create that page (via a template) either as a separate document or as a
separate section, with the Page Setup values adjusted to leave only the actual space available. The writer then
must make his/her title fit within that space—which can be encouraged by supplying a “dummy” text string
with the desired font and font size, with the writer then simply replacing that text with his/her title—which
will be displaced to the next page of the work document if it is too long. The need to include any other text on
the page (such as a repetition of the StorageWorks log at the top and/or the Digital address at the bottom) can
be taken care of simply by preprinting a stock of such pages, to obtain the unchanging information, and then
using the preprinted page when it is time to print a cover.
The cover setup is relatively straightforward. To compensate for the rounded corners, I simply added
0.05” to the applicable measurements, finding that the Page Setup utility will accept some values but round
others off. At the moment, for example, the cover aperture, shown in Section 1 of this file, is set to be 2.4”
below the top of the page, 2.4” from the left edge (2.33” rounded off), 6.55” from the bottom, and 1.0” (0.97”
rounded off) from the right side. This leaves a printable “hole” that measures 2.05” high by 5.1” wide.
As should be patently obvious, however, this space restriction severely limits how much text can be fit
into that space ... which becomes a problem to us, because the engineering minds that create these titles like
Germanic constructions full of semi-informative adjectives.
Since a “point” equals 0.01384 inch, and since WinWord presumably adds a standard 2-point (or more)
gutter spacing between lines, this means that each line of text will consume 44 x 0.01384 = 0.609 inches,
which means that three lines (1.827”) will fit comfortably within the 2.05”-high aperture—but that those lines
will be limited to a length of approximately 30 picas each, meaning that there will not be space for more than
two or three words per line (four if they are fairly short words).
Experimentation indicates that this all changes with different fonts, however. I find that I can get three
lines of Times New Roman at 42 points and four lines at 31 points ... but that Palatino (on my home system)
requires reduction to 41 points (as currently shown here) in order to get three lines, meaning that restricting
the title to 42 points will limit the title to two lines of text, containing between four and eight words!
02-18-94: All of that went out the window with the further clarification that the aperture also had to include a
line under the title, followed by the publication category (User Manual, etc.), followed—with an appreciable
space—by the order number ... with the additional news that the coversheet font was Arial (which is a
TrueType font that gets translated into Helvetica in our print setup, anyway).
So—I’ve incorporated those into the template setup, finding that the title is restricted to two lines for a
total of three or four words at 42 points ... and works down from there.
02-18-94: While I was typing that, it changed again. The semiofficial word currently is that the title will be
24-point Palatino, while the category will be 14-point Helvetica and the order number will be 9-point
Helvetica.
I’ve also set up the second page of this template to print the StorageWorks logo, currently set up at a size
that met Carl Peterson’s approval, which will be preprinted on the sheet used for the title page. For the record,
the preprinted page has to be put in the 4M machine upside down (logo image on bottom), bottom end first
into the paper tray.

Introduction
This chapter introduces and describes the product features of the SWXTL-BL Tape Mini-Library.
1.1 Product Overview
The SWXTL-BL tape mini-library (Figure 1-1) is a high performance, streaming
cartridge tape product designed for use on mid-range, and high-end computing systems.
As a mini-library that performs automatic tape operations, the SWXTL-BL contains a
high-capacity DLT tape drive and a five-cartridge, SCSI-2 medium changer device
(loader). With a typical load /unload cycle time of 20 seconds, the mini-library can
provide unattended back-up of 100 GB (compressed) in about 11 hours.
The half inch tape drive uses data compression and compaction. The drive features a
formatted capacity of 20 GB per cartridge (compressed) and a sustained user data transfer
rate of 2.5 Mbytes/second (assumes a 2:1 data compression factor). The drive has a dual-
channel read/write head and Digital Lempel-Ziv (DLZ) high-efficiency data
compression. The drive tape mark directory maximizes data throughput and minimizes
data access time. The mini-library is housed in a tabletop enclosure and includes single-
ended or differential driver/receivers.
1.1.1 Fast Data Transfer Rate
Used for unattended backups or archiving, the mini-library allows you to back-up a high
data capacity at a high speed. When the SWXTL-BL operates in a non-compressed
mode, the mini-library drive has a maximum transfer rate of 1.25 Mbytes/second. When
operating in the compressed mode, the maximum transfer rate is 2.5 Mbytes/second write
and 3 Mbytes/second read.
1.1.2 High Capacity
The amount of data you can store on a tape cartridge can be 10 GB native capacity
(uncompressed), or if you select the compression mode, 20 GB compressed. Built-in data
compression increases the cartridge capacity and transfer rate 2 to 2.5 times.
The removable magazine in the mini-library has the capacity for five cartridges,
providing a total capacity of 100 Mbytes compressed, or 50 Mbytes uncompressed. You
can select compression on the mini-library front panel or through the host by using the
SCSI MODE SELECT command.

Figure 1-1. SWXTL-BL Tape Mini-Library
1.1.3 Compaction
The compaction feature of the mini-library tape drive helps you store data efficiently. A
read/write data cache of 2.0 Mbytes allows working space for the compaction, enabling
maximum use of available tape space.
1.1.4 Media Durability
The tape cartridge media, which provides superior media durability and data reliability,
can endure 500,000 passes and has a shelf life of 20 years.
1.1.5 Compatibility
Digital Equipment Corp. is committed to maintaining compatibility within the DLT
family of tape products. The SWXTL-BL, the second generation of the mini-library
family, offers users a smaller form factor and low cost alternative to the first generation
mini-library, the TZ877 (Digital Part No.). This device features an LCD display that
shows the operation of the mini-library with abbreviated messages.
The mini-library drive’s default density is 10 Gbytes (TZ87 format) compressed. The
mini-library drive can write 2.6 (TK85 format), 6.0 (TK86 format), and 10 Gbytes
(TZ87) tape formats for 100% interchange compatibility with earlier TZ8x drives. On a
write from BOT, the mini-library reformats the cartridge if a different density is selected.

Chapter 1. Introduction
Tape Mini-Library User's Guide 3
Older data cartridges can be loaded for read or read/write purposes into the SWXTL-BL
mini-library. Any cartridges recorded in 2.6, 6.0, 10, or 20 Gbyte (assumes 2:1 data
compression) can be read and written by the drive in the SWXTL-BL. Refer to Table 1-1
to determine cartridge compatibility with the SWXTL-BL mini-library.

2:1 data compression) GB mode, as selected
1Read/write, backward compatible with drive of selected density.
2Recording format can be changed to 2.6, 6.0, 10, or 10C (compressed) GB mode on a write
from BOT (beginning of tape).
The SWXTL-BL complies with the ANSI standard for SCSI-2. The tape media format
follows applicable ECMA approved and ANSI proposed standards.
1.1.6 Code Update Capability
The mini-library drive includes Flash EEPROM technology that allows easy on-site
installation of code updates from tape or over the SCSI bus.
1.1.7 Embedded Diagnostics
The mini-library has embedded power-on self-test (POST) and diagnostics that run
automatically when you turn on the power.

Never force or try to open the magazine door manually.
Always use the OPEN push-button on the operator control
panel which opens it electronically.
9. Turn the locking lever counter clockwise at the front of the mini-library (Figure 2-3)
to rotate the magazine locking mechanism. This allows you to remove the magazine
from the mini-library.
2.3 Introduction to the Mini-Library
The mini-library includes a DLT2000 tape drive, a media loader, and a five-cartridge
removable magazine. The same SCSI target controller controls the tape drive and the
media loader. If the controller detects the loader’s presence when the system is turned on,
the loader is presented as a SCSI-2 medium changer device on LUN (Logical Unit) 1. If
you issue the SCSI-2 medium changer commands to the SWXTL-BL:
• Random access is enabled to the media stored in the magazine slots
• Sequential access is disabled to the media supported automatically in the
auto-loading mode
If you do not issue the SCSI-2 medium changer commands, the default mode of
operation is sequential access to the media supported in the auto-loading mode. Auto
loading is implemented as a side effect of the SCSI UNLOAD command (Table 2-4).
Table 2-4. SCSI-2 Command Conditions
IF. . . Then . . .
An unload is specified. After winding the tape back into the cartridge and moving the
cartridge from the drive to the magazine slot from which it
came, the cartridge in the next slot is moved from the
magazine into the drive and made ready.
The next slot is empty, or the
cartridge unloaded was for the
last slot in the magazine.
No cartridge is loaded into the drive.

2.4 Configuring and Installing the Mini-Library
This section describes the configuration rules and SCSI cable connections for the
mini-library.
NOTE
Unless otherwise specified, the mini-library is set to SCSI ID 0
at the library.
2.4.1 Configuration Guidelines
Your system uses the SCSI ID to identify, or address, the mini-library. Follow these
guidelines when configuring (Table 2-5) the mini-library for use on your system.
Table 2-5. Configuration Guidelines
If you are installing the mini-library as . .
.Then . . .
The only SCSI device on the bus or one of
multiple SCSI devices on the bus. Be sure to use a SCSI ID that is unique from any other device or system ID on the SCSI bus.
The last or only device on the SCSI bus. You must terminate the bus by installing a
terminator.
2.4.2 SCSI Cable Connection
Make the SCSI cable connection between the mini-library and the host system as
follows:
1. Ensure the power switch on the mini-library is turned off.
2. Connect one end of the SCSI cable to the left most connector on the rear panel of the
mini-library (see Figure 2-2) and snap the wire cable clamps into place to secure the
cable.
3. Connect the other end of the SCSI cable to the SCSI connector on the host system,
or for daisy-chained configurations, another SCSI device.
4. If the mini-library is the last SCSI device on the bus, ensure a SCSI bus terminator is

The POST (Power On Self Test) test runs automatically when the mini-library is turned
on. The POST test checks the integrity of the installation to ensure it is wired and
functioning properly. Perform the POST test as follows:
1. Set the power switch on the rear panel of the mini-library to on (1).
2. Observe the sequence of events on the front panel display of the mini-library. They
should be as defined in Table 2-6.
3. If any of the display messages in the sequence of events did not occur, refer to
Table 2-7 for a POST test analysis.
