External partitioning of an automated data storage library into multiple virtual libraries for access by a plurality of hosts
TL;DR: In this article, the authors present a method and processor external to an automated data storage library for partitioning the data storage libraries into multiple virtual libraries for access by a plurality of hosts.

David Butka,Brian Gerard Goodman,Leonard George Jesionowski,Michael Philip McIntosh,Robin Daniel Roberts,Raymond Yardy +5 more
TL;DR: In this article, a power management system and method for multiple redundant power supplies is presented, where each power subsystem includes a power supply and a controller coupled to a power bus, and a master controller is provided to monitor normal operating conditions of the power subsystems and communication bus, even in the event of total or partial communication failure.
Patent
Security in an automated data storage library
TL;DR: In this article, an automated data storage library accesses data stored on storage media contained in cartridges in response to commands from an external host, where the library modifies the contents of the cartridge memory to prevent access to the data.
Patent
Media vaulting in an automated data storage library
TL;DR: In this paper, a logical library partition vault is created in the automated data storage library that is not accessible by any host computer and can only be accessed by an operator using a secure means.
Patent
Data storage library with efficient cartridge insert
TL;DR: In this paper, a location-centric library host manages cartridge movement according to functional storage addresses and functional I/O addresses, which are virtual locations used by the host in managing cartridge locations.
