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. NOTE: A magazine that has been reserved for import/export service can not be used for 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.
