A method for adding intelligence into the tape drive subsystems of a media storage library. The present invention improves overall system availability by enhancing existing control, monitoring, and diagnostic functionalities. As a result of inserting intelligence into the drive trays, certain control and monitoring functions traditionally performed by the main library controller may be performed locally at the drive trays. Since certain functions are performed locally at the drive trays, fewer connections are required between the tape drive trays and the main library controller. Also, the main library controller's performance is not degraded as the number of tape drives increases. The present invention also provides flexibility to the storage system since new features and functions may be added to the drive tray subsystem without the need to modify the base library cabling infrastructure.

Method for intelligent tape drive subsystem control and monitoring in a tape library

A system and method for transmission of communication signals between a controller and a robotic device in a data storage library. The system and method include a substantially planar electrical insulator having opposed first and second sides, and first and second substantially planar oppositely charged electrical conductors on the first and second sides of the insulator for use in providing electrical power to the robotic device. The system and method also include circuitry for generating the communication signals for transmission between the controller and the robotic device on one of the first and second conductors. The width of the second conductor is less than the width of the first conductor and the second conductor is substantially centered on the second side of the insulator relative to the width of the first conductor to reduce fringing of an electromagnetic field resulting from a transmitted communication signal.

System and method for transmitting communication signals to an automated robotic device in a data storage system

A system, method, and product are disclosed for associating subcomponents with a storage library. A unique identifier is stored in a particular storage library. Each subcomponent that is a part of the particular storage library is then associated with the particular storage library by storing a copy of the unique identifier within each subcomponent. In order for a subcomponent to be usable by a particular storage library, the particular storage library's unique identifier must be stored within the subcomponent.

A system and method for distributing electrical power to an automated robotic device for transporting media cartridges in a data storage library. A power distributor includes multiple sections having first and second electrical conductors. A first power supply powers the first and second conductors of each section of the power distributor, and is connected to the first and second conductors of at least two section of the power distributor. A second power supply powers the first and second conductors of each section of the power distributor, and is connected to the first and second conductors of at least two sections of the power distributor. Power to each section of the power distributor is maintained in the event of a failure of one of the power supplies, and in the event of an electrical discontinuity in the power distributor.

Redundant power supply system and method for an automated robotic device in a data storage system

The present invention provides two redundant tape library controllers that mirror each other's function. A secondary controller can immediately take over from the primary controller if the primary unit fails or if a redundant path leading to the primary controller fails.
