Controller cards
This section explains the function of the three major cards that control the library. These cards are:
• Library robotics controller
• Interface Manager card
• Interface controller
Library robotics controller
The library robotics controller contains firmware to control the robot, communicate with the Interface
Manager card, manage the library servo and vision control, and monitor the door and load port sensor
status.
Robot commands are sent from hosts in the SAN to an interface controller, which directs them over an
internal Ethernet network to the library robotics controller. The library robotics controller translates these
commands into movements to be performed by the robot.

HP StorageWorks Interface Manager card
The HP StorageWorks Interface Manager card is an HP proprietary management card designed to
consolidate and simplify the management of multiple interface controllers installed in the library. It also
provides SAN-related diagnostics and management for library components, including the interface
controllers, tape drives, and robotics. The Interface Manager card, in conjunction with HP StorageWorks
