Chapter 1

1Overview

This chapter provides an overview of the ATL M-Series libraries and their features.

Library Capacity

ATL M1500

Library

ATL M2500

Library

The ATL M1500 library can contain up to two tape drives and up to 21 DLT/SDLT cartridges or 25 LTO cartridges. The cartridges are stored in two independently removable cartridge magazines and one fixed cartridge slot.

The ATL M2500 library can contain:

•Up to five tape drives and up to 84 DLT/SDLT cartridges or 100 LTO cartridges

•Six tape drives and up to 73 DLT/SDLT cartridges or 87 LTO cartridges

ATL M-Series User’s Guide

Chapter 1 Overview

SCSI Configuration

The cartridges are stored in up to eight independently removable cartridge magazines and up to four fixed cartridge slots.

SCSI Configuration

The ATL M1500 and ATL M2500 library modules come configured for LVD SCSI. One SCSI bus is provided for the library robotics and for each tape drive installed. These SCSI buses are SCSI-2 fast/ wide (8/16 bit), Ultra SCSI, Ultra 2 SCSI, or Ultra 3 SCSI, depending on the drives installed.

Library Scalability

The ATL M1500 and ATL M2500 library modules can be used as stand-alone libraries, or can be combined with other ATL M1500 and ATL M2500 library modules and a StackLink mechanism in a standard 19-inch rack to form a larger library system (called a multiple library stack). The multiple library stack appears as a single large capacity library to the host.

The StackLink mechanism connects the library modules in the multiple library stack and transports cartridges from module to module. Each tape drive has access to all the tape cartridges in the stack.

Once the StackLink mechanism is installed in the rack, you can add library modules simply by sliding them into place and making the necessary electrical connections.

Table 1 lists the capacities of all the sizes of multiple library stack you can create using ATL M1500 library modules. Table 2 lists the capacities of all the sizes of multiple library stack you can create using ATL M2500 library modules. You can obtain different capacities by combining ATL M1500 and ATL M2500 library modules in a multiple library stack.

Back Panel

Figure 5 ATL M1500

Back Panel

Each cartridge magazine holds 10 DLT/SDLT cartridges or 12 LTO cartridges. The bins in the left magazines are numbered from 1 through 10 (or 12 in LTO libraries) from front to back. The bins in the right magazines are numbered from 1 through 10 (or 12 in LTO libraries) from back to front.

The ATL M1500 has one fixed cartridge slot behind the left magazine. The ATL M2500 has four fixed cartridge slots, one behind each left magazine. The fixed cartridge slots can be used as additional data cartridge bins, or can be used to hold cleaning tapes, which can be moved to a tape drive when cleaning is required.

A bar code reader is attached to the library’s robotic hand. This bar code reader automatically identifies the cartridges in the library, if the cartridges are fitted with acceptable bar code labels.
