The IBM TotalStorage Enterprise Automated Tape Library (3494) (Figure 1) can be attached to host systems by two methods. The first method is attachment to host systems through a communications path to the control unit of an IBM 3490E, an IBM 3590, an IBM 3592, or a combination thereof. The second attachment method stems directly from the library manager to open systems hosts through a host attachment feature. This attachment provides direct communication between the open system host and the 3494 library manager.

The details for each callout in Figure 1 are explained in the text that follows.

This ATLDS is capable of supporting multiple control units and tape drives. See Table 1 for more information concerning configuration capabilities.
