performance, and physical configuration/expansion options.
The MiniLibrary system is an expandable, modular tape library system that
combines DLT technology drives with advanced robotics. The MiniLibrary
system is designed for high duty-cycle on-line and near-on-line applications. It
is a superior performer in high-volume backup and archival service.

Modules
The MiniLibrary system is based on three types of modules:
■
Expansion Unit (master)
■
MiniLibrary Base Module
■
Data Unit
The MiniLibrary system consists of one Expansion Unit and up to five
MiniLibrary Base Modules and Data Units in combination stacked in a rack.
The Expansion Unit can move media freely between itself, the MiniLibrary
Base Module, and the Data Unit by way of the system’s robotically controlled
Pass-Through Mechanism (PTM).

In a MiniLibrary system, you can combine modules to provide the right
combination of capacity and performance to meet your present storage
requirements. The Compaq MiniLibrary storage architecture lets you add
modules to optimize throughput and capacity as your needs change.
There is a specific Low Voltage Differential (LVD) version of the Expansion Unit for
NOTE:
the TL891DLX. Also, the Data Unit can be used in conjunction with all MiniLibrary
systems (TL881, TL891, TL891DLX, and TL891DX) because there is no SCSI bus
connection to the unit.
MiniLibrary Storage Architecture
When connected as a system, the robotics in the Expansion Unit act as
commanded by the host computer(s). The host(s) need no knowledge of the
internal geometry of the system, or of the actions or capabilities of the
MiniLibrary Base Modules or Data Units.
The Expansion Unit presents to the host(s) a single SCSI medium changer
device with a single SCSI medium transport element, several SCSI storage
elements equal to the total number of cartridge magazine slots, a number of
SCSI import/export elements as specified by the user during configuration of
the Expansion Unit, and a number of SCSI data transfer elements equal to the
total number of drives in the system.
Flexibility
The Compaq MiniLibrary storage architecture is uniquely suited to growing
storage needs. Its flexible library robotics system lets you start with a system
configured to your present requirements, confident that as your storage needs
evolve, you can easily modify the MiniLibrary by adding modules and
extending the PTM. Add drives for faster performance or magazine space for
greater capacity, as needed. Then just turn on the power and the system
immediately updates the system map so the host is informed of the expanded
capability.
Expansion Unit
The Expansion Unit (Figure 1-1) integrates the robotics in the individual
modules into a single, coordinated library robotics system. The Expansion
Unit performs and maintains an inventory of all media present in the system,
including bar code data. All necessary system control operations can be
performed from the control panel of the Expansion Unit, as well as from the
host via software. The SCSI interface for the library robotics is designed for
high-speed communication with the host and for Fast Wide SCSI
configurations.

In addition to its system control functions, the Expansion Unit has a
16-cartridge magazine with a random access robotic mechanism. The module
robotics moves cartridges between the PTM and any of the 16 cartridge
storage locations.
You can designate a magazine in one of the MiniLibrary Base Modules as a
mail slot for inserting or removing one or more single cartridges, which
implements the SCSI IMPORT/EXPORT commands.
A magazine that has been reserved for import/export service can not be used for
NOTE:
data storage.
MiniLibrary Base Module
The MiniLibrary Base Module (Figure 1-2) has one or two DLT tape drives
and a 10-cartridge magazine with a rugged random access robotic mechanism.
The drives use the DLT tape IV cartridges, which provide a native capacity of
20 GB, 35 GB, or 40 GB per cartridge depending on the drive type. All models
can also read and write DLTtape III and DLT tape IIIxt cartridges. Both read
and write densities are selectable from the front panel, and under SCSI control
from the host. These units are available as differential rack-mount or table-top
versions, as well as a single-ended table-top-only version.

SCSI Interface Configurations
DLT drives in TL891 MiniLibraries use either a fast-wide High Voltage
Differential (HVD) or a fast-wide, single-ended SCSI interface. The choice
must be made at the time of purchase. DLT drives in a TL891 MiniLibrary
system use a fast-wide HVD SCSI interface. DLT drives in a TL891DLX
MiniLibrary use a fast-wide auto-sensing Low Voltage Differential
(LVD)/single-ended SCSI interface.
SCSI Bus Performance Considerations
Data Transfer Rate
The data transfer rate of the MiniLibrary is dependent on the type and number
of drives and on the SCSI bus configuration. The bandwidth of the SCSI bus is
limited. As a result, the transfer rate of DLT drives can be limited by sharing a
SCSI bus with another tape or disk drive. It is recommended that the
MiniLibrary be installed on its own controller for optimum performance.
Drives
System Description
1-7
With a standard SCSI interface, modules equipped with DLT 20/40 drives
have a native data transfer rate of 1.5 MB/s; 3.0 MB/s for two drives. Modules
equipped with DLT 35/70 drives have a native data transfer rate of
5 MB/s; 10 MB/s for two drives. Modules equipped with DLT 40/80 drives
have a native data transfer rate of 6 MB/s; 12 MB/s for two drives. The rates
for compressed data are dependent on compression ratio, record size, data
type, and other system parameters, but average 1.7 times greater than the
native rate.
Internal Cabling Configuration
The differential and Low Voltage Differential (LVD) versions of the
MiniLibrary Base Module are wired in an independent-bus SCSI
configuration. That is, the robotics and each of the drives has its own SCSI
bus. SCSI jumpers are available for those applications requiring that some
combination of drives and robotics can be daisy-chained to a single SCSI bus.
The single-ended table-top version, however, has the first drive daisy-chained
internally to the robotics in order to reduce cable length. These configurations
are described in more detail in Chapter 3, “Installation.”

Physical Configuration
The Expansion Unit must be mounted at the top of the stack, which places its
control panel at a convenient height. The control panels of the MiniLibrary
Base Modules and Data Units are of secondary importance, as they serve
mainly to help localize system failures. When installed, the motor drive
assembly of the PTM is directly behind the Expansion Unit.
MiniLibrary Base Modules can be installed anywhere below the Expansion
Unit, in any order. There can be a slight performance advantage in making the
MiniLibrary Base Modules contiguous, but gaps are permitted. The size of a
gap is limited by the fact that the same number of 7- inch track sections must
bridge each gap. For safety, available cover plates should be installed on all
PTM sections that are not connected to MiniLibrary modules.
The Expansion Unit senses the position of each module during initialization at
power-up. Even if there are gaps between modules, the system will operate
correctly. If you plan to leave gaps between modules, be sure to order
additional PTM track segments and cover plates equal to the length of the gap.
System Expansion
Features
A MiniLibrary system can be expanded in capacity and performance by
adding or removing TL881/TL891/TL891DLX modules. Associated with the
Expansion Unit and each MiniLibrary Base Module is a section of the
PTM. System firmware integrates all of the robotics of these system modules
with that of the PTM into a single high-performance library robotics system.
There are a number of important external features to note about the Expansion
Unit, the MiniLibrary Base Module and the Data Unit. See Figures 1-4
through 1-7 to locate the features described in the following sections.

Control Panel
The control panels for all modules are the same, except for the number of LED
indicators. The control panel features a 4-line by 20-character, backlit LCD
display, three or four LED indicators, and four buttons. The buttons let you
navigate through the menu structure to select and display operating modes,
device status, diagnostic and maintenance functions, device history and error
statistics, and system configuration. The functions of the control panel are
described in detail in Chapter 2, “Operation.”

Display
The backlit, 4-line by 20-character control panel display provides a highly
intelligible presentation of drive and loader status, menu choices, and error
messages. The scrolling feature greatly expands the amount of information
available to you. In the Expansion Unit, status information is available for the
entire system. The MiniLibrary Base Modules display other information as
needed for localizing malfunctions.
Magazine Security Lock
The magazine security lock is a key-operated switch on the front panel of each
module. It can be used to prevent inadvertent removal of the cartridge
magazine.
Power Supply
The AC power switch is located on the front panel of the module. The
autoranging power supply adjusts automatically to either of two operating
voltage ranges. The ranges are 100-120 VAC and 200-240 VAC. The power
supply is capable of operating at 50 or 60 Hz without any adjustment or
modification. AC power is supplied to the power supply by a single
IEC-compatible socket that can be connected to any properly grounded outlet.
