Chapter 1 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 TM 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.
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. NOTE: There is a specific Low Voltage Differential (LVD) version of the Expansion Unit for the TL891DLX.
System Description 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.
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. 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.

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. 1 2 3 4 5 6 SHR-1677 Figure 1-3.
System Description 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.
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. When installed, the motor drive assembly of the PTM is directly behind the Expansion Unit.
