The IBM TS4500 is a highly scalable, stand-alone tape library that provides high-density tape storage and
high-performance, automated tape handling for open systems environments. Figure 1-21 shows a three-
frame version of the TS4500 tape library. An individual library consists of one base frame and up to 17
expansion frames and can include up to 128 tape drives and more than 23,000 tape cartridges.
