Abstract
A data library comprising a plurality of partitions, at least one data transfer element, each of the data transfer elements assigned to one of the partitions and assigned an internally unique element address, a plurality of data storage element slots, each of the slots assigned to a partition and assigned an internally unique element address, at least one media transport element shared by the partitions to move media between the slots and the at least one data transfer elements, the transport assigned an internally unique element address, and a library controller that assigns a different logical unit designation to each of the partitions and that assigns external element addresses to the transport, the data transfer elements, and the slots for each of the partitions and maps the internally unique addresses to the external addresses, the controller restricting movement of media to and from the slots assigned to a same of the partitions.
