ABSTRACT:
Embodiments of the present invention provide systems and methods of centralized mapping of media library partitions. According to one embodiment, the present invention can include a first controller connected to a data transport element of a media library and a second controller connected to a media changer of the media library. The first controller can receive a command from a host application based on a media library partition presented to that host and forward the command to the second controller. The second controller can receive the command from the first controller, translate logical addresses referenced in the command to physical addresses and forward the command to the media changer. The second controller, can also prioritize the command on a FIFO basis or according to other prioritization scheme known in the art.
