Page 18: System Description
Chapter System Description Introduction This chapter describes the features of the Expansion Unit, the Base Module, and the Data Unit of the Compaq StorageWorks TL881/TL891 Family MiniLibrary System , including storage architecture, SCSI interface, bus performance, and physical configuration/expansion options. The MiniLibrary system is an expandable, modular tape library system that combines DLT technology drives with advanced robotics.
Page 19: Minilibrary Storage Architecture
1-2 Compaq StorageWorks TL881/TL891 Family MiniLibrary System Reference Guide 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.
Page 20: Expansion Unit
System Description 1-3 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.
Page 21: Minilibrary Base Module
1-4 Compaq StorageWorks TL881/TL891 Family MiniLibrary System Reference Guide 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.

1-6 Compaq StorageWorks TL881/TL891 Family MiniLibrary System Reference Guide Data Unit The Data Unit (Figure 1-3) has a 16-cartridge magazine and a random access robotic mechanism, but no tape drives. The module robotics, under control of the Expansion Unit, moves cartridges between the PTM and any of the 16 cartridge storage locations.
Page 24: Scsi Interface Configurations
System Description 1-7 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.
Page 25: Physical Configuration
1-8 Compaq StorageWorks TL881/TL891 Family MiniLibrary System Reference Guide 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.

Page 67: Tape Requirements
2-34 Compaq StorageWorks TL881/TL891 Family MiniLibrary System Reference Guide Tape Requirements The MiniLibrary system uses ECMA-approved, ANSI proposed-standard DLT tape cartridges. The DLT tape cartridge is a four-inch square plastic cartridge. DLT tapes are available in three types, each with varying length and capacity, as listed in Table 2-11.
Page 68 Operation 2-35 execute, with resulting errors or hangs, failure to unload, and apparent need to swap out the drive are a few such conditions. NOTE: DLT tape cartridges should be stored vertically, in their original translucent plastic boxes, until you want to reuse them and after they have been removed from tape drives. When tapes are stored in an environment different from that of the tape drive, ensure that they are acclimatized, by moving them to a location in close proximity to the drive before attempting to use them.

Page 71: Storage Architecture
2-38 Compaq StorageWorks TL881/TL891 Family MiniLibrary System Reference Guide Storage Architecture The MiniLibrary architecture is uniquely suited and designed for expanding storage needs. The MiniLibrary architecture enables the robotics in each of the MiniLibrary components to exchange cartridges with the PTM, and integrates the robotics in the individual components and the PTM into a single high-performance library robotics system.
Page 72: Minilibrary Base Module
Operation 2-39 MiniLibrary Base Module The MiniLibrary Base Module has either one or two DLT drives and a 10-cartridge magazine with a random access robotic mechanism. Data Unit The Data Unit has a 16-cartridge magazine, a random access robotic mechanism, and no tape drives. The module robotics, under control of the Expansion Unit, moves cartridges between the PTM and any of the 16 cartridge storage locations.
Page 73: Internal Cabling Configuration
2-40 Compaq StorageWorks TL881/TL891 Family MiniLibrary System Reference Guide Internal Cabling Configuration The differential MiniLibrary system is wired in an independent-bus SCSI configuration; the robotics and each of the drives has its own SCSI bus.
