Chapter 1. Introduction
This chapter introduces the IBM System Storage TS3500 Tape Library, machine type
3584, also referred to as the 3584 Tape Library. The information in this chapter is
specific to the TS3500 Tape Library with the Advanced Library Management
System (ALMS).
Overview
This topic describes the IBM System Storage TS3500 Tape Library, a highly scalable,
stand-alone device that provides reliable, automated tape handling and storage for
both mainframe and Open Systems environments.
Figure 2 on page 2 shows a 6-frame version of the TS3500 Tape Library. An
individual library, or
library string , consists of one base frame and up to 15
expansion frames and can include up to 192 tape drives and more than 20 000 tape
cartridges. The flexibility to connect multiple library strings to create a
shuttle
complex greatly increases opportunities for growth, as well as the maximum
cartridge capacity. In addition to scalability, the TS3500 Tape Library offers the
following enhancements:
v
Enhanced data accessibility through dual accessors that increase speed and
provide failover protection
v
Enhanced data security through support for tape drive encryption and
write-once-read-many (WORM) cartridges
v
Increased storage capacity with high-density (HD) frames that greatly increase
capacity without requiring more floor space
v
Increased growth flexibility with shuttle technology, even in physically
constrained environments
v Greatly increased cartridge capacity in a shuttle complex without the need for
additional tape drives
These features are explained in greater detail throughout this chapter.
