Chapter Introduction The TL881 MiniLibrary This chapter describes the features of the MiniLibrary Expansion Unit, the MiniLibrary Base Module, and the MiniLibrary Data Unit of the 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 drive with advanced robotics.
Page 16: The Expansion Unit
1-2 Compaq TL881 Minilibrary System Users Guide In a MiniLibrary system, you can combine modules to provide the right combination of capacity and performance to meet your present storage requirements. Compaq’s MiniLibrary storage architecture lets you add modules to optimize throughput and capacity as your needs change. MiniLibrary Storage Architecture When connected as a system, the robotics in the Expansion Unit act as commanded by the host computer(s).
Page 17: Figure 1-1. Expansion Unit Front View
Introduction 1-3 SHR-1194 Figure 1-1. Expansion Unit Front View 16-Cartridge magazine Unlock /Open button Magazine security lock Locked indicator Control panel Power switch In addition to its system control functions, the Expansion Unit has a 16- cartridge magazine with a rugged random access robotic mechanism. The module robotics moves cartridges between the Pass-Thru Mechanism and any of the 16 cartridge storage locations.
Page 18: The Minilibrary Base Module
1-4 Compaq TL881 Minilibrary System Users Guide The MiniLibrary Base Module The MiniLibrary Base Module (Figure 1–2) has one or two DLT 20/40 tape drives and a 10-cartridge magazine with a rugged random access robotic mechanism. The TL881 using one or two DLT20/40 series drives, also uses the DLTtape IV cartridges, which provide a native capacity of 20 GB per cartridge.
Page 19: The Data Unit
Introduction 1-5 The Data Unit The Data Unit (Figure 1–3) 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 Pass-Thru Mechanism and any of the 16 cartridge storage locations. SHR-1194 Figure 1-3.
Page 20: Physical Configuration
1-6 Compaq TL881 Minilibrary System Users Guide Drives With a standard SCSI interface, modules equipped with DLT 20/40 drives have a native data transfer rate of 1.5 MB/second, 3.0 MB/sec for two drives. The rates for compressed data are dependent on compression ratio, record size, data type, and other system parameters, but averages approximately 1:7.
Page 21: Features
Introduction 1-7 System firmware integrates all of the robotics of these system modules with that of the Pass-Thru Mechanism into a single high-performance library robotics system. Features There are a number of important external features to note about the Expansion Unit, the MiniLibrary Base Module and the Data Unit.
