Page 9: Chapter 1 - Introduction
In a DLT LibraryXpress System, you can combine modules to provide the right combination of capacity and performance to meet your present requirements. Overland Data’s SmartScale Storage™ architecture lets you change or add to the mix of modules to optimize throughput, capacity, or both as your needs change. -
Page 10: Smartscale Storage™ Architecture
Flexibility The DLT LibraryXpress Smartscale Storage™ architecture is uniquely suited to growing storage needs. Overland Data’s Smartscale Storage architecture enables the robotics in each of the LibraryXpress modules to exchange cartridges by means of the XpressChannel™ pass- through elevator, and integrates the robotics in the individual modules and the Global Control’s XpressChannel into a single high-performance library robotics system. -
Page 11: The Base Module
The Base Module Description The Base Module has one or two DLT drives and a 10-cartridge magazine with a rugged random access robotic mechanism. Models The DLT LibraryXpress Base Module is currently available in six models. The first digit of the model number refers to the DLT drive model series. -
Page 12: Scsi Bus Performance Considerations
SCSI-2 buses may be up to 25 meters. The internal wiring of the modules in a single-ended LibraryXpress system may consume a significant fraction of the allowed length, leaving very little extra for interconnection between modules and for attachment to the host. Overland Data strongly urges use of the differential configuration for best performance. -
Page 13: System Expansion
System Expansion A DLT LibraryXpress System may be expanded in capacity or performance or both by adding or removing modules. Associated with each module is a section of the XpressChannel™ pass-through cartridge elevator. Smartscale Storage system firmware integrates the robotics in the individual modules and the Global Control’s XpressChannel into a single high-performance library robotics system. -

Page 21: Chapter 2 - Installation
Chapter 2 - Installation Introduction There are three major steps to the installation of a DLT LibraryXpress System: mechanical installation, cabling and configuration. Mechanical installation consists of: • assembling the XpressChannel (the two-module system comes factory assembled), • installing the module mounting slides in the rack, •... -
Page 22: Positioning The Modules
Positioning the Modules The Global Control Module must be mounted at the top of the stack, which places its control panel at a convenient height. The control panels of the slave modules are of secondary importance, as they serve mainly to help localize system failures. When installed, the motor drive assembly of the XpressChannel is directly behind the Global Control Module. -
Page 23: Figure 2-1. Xpresschannel External Parts
Figure 2-1. XpressChannel External Parts Note: The slide extensions, (6) in Figure 2-1, are not enclosed with the XpressChannel parts. They are supplied as part of the installation hardware for the slides that come with each of the modules. Follow the instructions for installing rack slides, later in this chapter. After the rack slides and the slave modules are in place, and after the XpressChannel is assembled, you will install the XpressChannel in the rack by attaching the support braces (5) to the slide extensions (6) using the angle brackets (7) and L-shaped nut plates (8). -
Page 24: Orientation Of Parts During Assembly
Figure 2-2. XpressChannel Car (Front View) Figure 2-3 Car Rear View Showing Belt Block The belt block comes fastened to the back of the car with two captive screws. Carefully note the orientation of the block with respect to the car, as shown in Figure 2-3. Orientation of Parts During Assembly To determine the orientation of an extension section, examine the flanges on the edges of the section, and note that they are dissimilar. -
Page 25: Preparing To Assemble The Xpresschannel
Figure 2-4 shows a typical XpressChannel assembly. The motor drive section always goes on top, and the base section with the idler pulley always goes on the bottom. Extension sections are mounted between the motor drive section and the base section. All sections are joined together with tie bars. -
Page 26: Figure 2-4 Xpresschannel Assembled
Figure 2-4 XpressChannel Assembled Place pairs of tie bars so that they straddle all of the joints where sections come together. Be sure that the beveled edge is toward the inside corner of the sections. Install two M3 x 20 mm Phillips sems screws through each tie bar into the threaded holes in the flanges of the extrusion sections. -
Page 27: Installing The Belt
Firmly press the neighboring sections together while tightening the two M3 x 20 mm screws through each tie bar into the flanges of the sections. Alternately tighten the screws into the flanges and those into the sides of the extrusions to ensure that each tie bar is drawn into the corner of the extrusion. -
Page 28: Figure 2-5 Threading The Belt Through The Drive Section
Figure 2-5 Threading the Belt Through the Drive Section Refer to Table 2-1 for the required belt length for your system. After double- checking the length specified, cut the belt between teeth. With the toothed side of the belt toward you, position the right end of the belt about halfway along the XpressChannel. -
