It is suited for mid-range to high-end servers, mainframe systems, and tape library automation systems. The LTO-2 Half-Height Tape Drive uses Ultrium data cartridges. Its capacity is maximized using intelligent data compression. The drive has a native capacity of 200 Gbytes (400 Gbytes assuming 2:1 data compression). The LTO-2 Half-Height Tape Drive, as shown in figure 1 below, has a 5¼ inch half-height form factor with automatic electromechanical cartridge soft load. It is available as an internal and a desktop drive. · · The internal LTO--2 half-height drive is designed to fit in a 5¼-inch half-height drive bay. The desktop LTO--2 half-height drive is a stand-alone unit with a built-in power supply. Figure 1 Drive Covered in this User's Guide (Typical) LTO-2 Half-Height Tape Drive User's Guide 1 Chapter 1 Introduction Features Features 1 The following list summarizes the key features of the LTO-2 Half-Height Tape Drives. · · Performance - Up to 26 Mbytes-per-second native transfer. 13-Speed Transfer matches tape drive speed to that of the host and optimizes data transfers, resulting in shorter backup times and increased reliability. Two convenient form-factors: · · · · · · · · · · · · · · 5¼-inch internal form-factor for installation in a 5¼-inch halfheight space. External desktop form-factor. · Intelligent data compression maximizes performance and capacity by analyzing compressibility prior to recording. Cartridge memory enables fast loading of cartridges and stores pertinent information about the media. 32-Mbyte data buffer for extra fast backups on high-performance systems. Tape Alert drive performance monitoring and reporting. Third generation read channel for increased maturity and data integrity. Patented head positioner for increased data integrity. Shock dampened isolated chassis. Two levels of ECC for extra data safety and protection from errors. Reliable tape picking implementation for increased reliability. Custom-designed LSI circuitry for fast, efficient data processing. RISC processors for fast, efficient data processing. Supports a wide variety of UNIX platforms. 2 LTO-2 Half-Height Tape Drive User's Guide Chapter 2 2Installation and Quick Start This chapter explains how to install the internal and desktop LTO-2 Half-Height Tape Drives.

LTO-2 Half-Height Tape Drive User's Guide 5 Chapter 2 Installation and Quick Start Unpacking and Inspection Unpacking and Inspection Although drives are inspected and carefully packaged at the factory, damage may occur during shipping. Follow these steps to unpack the drive. 1 Visually inspect the shipping containers and notify your carrier immediately of any damage. 2 Place shipping containers on a flat, clean, stable surface; then carefully remove the contents. If the equipment is damaged, notify your Quantum representative. 3 Always save the containers and packing materials for any future reshipment. 2 Internal Tape Drive Guidelines and Cautions The following guidelines and cautions apply to handling and installing internal tape drives. Keep them in mind as you install the drive. · · Handle the drive by the sides rather than by the top cover to reduce the risk of dropping the drive or damaging it during installation. 2 Internal drives contain some exposed components that are sensitive to static electricity. To reduce the possibility of damage from static discharge, the drives are shipped in a protective antistatic bag. Do not remove the drive from the antistatic bag until you are ready to install it. Before you remove the drive from the antistatic bag, touch a metal or grounded surface to discharge any static electricity buildup from your body. Always lay the drive either on top of the antistatic bag or place it inside of the bag to reduce the chance of damage from static discharge. Install LVD drives only in an LVD environment. Do not mix LVD and HVD devices on the same SCSI bus. · · · 6 LTO-2 Half-Height Tape Drive User's Guide
