Library scalability
Libraries can be used as stand-alone libraries, or they can be combined in a rack to
form a larger library called a multiple library stack . A multiple library stack can
contain from two to four libraries. A multiple library stack appears to the host as one
library, and cartridges can be passed between libraries. See “Stacking libraries” on
page 15 for more information.
Table 3 provides information about each library combination.
