A fan assembly includes a radial blower unit configured to exhaust air radially from an inlet axis of the radial blower unit. The fan assembly also includes baffles each partially surrounding the radial blower unit. The baffles are rotatable between an open position and a closed position around respective pivot axes, and the baffles have respective centers of mass aligned with the respective pivot axes.

Air flow control in data storage systems

A system includes an enclosure with a first side wall, a second side wall, and a first wall assembly. The first wall assembly extends between the first side wall and the second side wall and includes a first shaft-holding portion, a first plurality of latch assemblies having a first latch end and a first pivot end, and a first shaft that extends within the first shaft-holding portion and that is coupled to the first plurality of latch assemblies at respective first pivot ends of the first plurality of latch assemblies.

Data storage retainer systems, methods, and devices

A system includes a chassis and a top cover assembly. The top cover assembly is coupled to the chassis. The top cover assembly includes a first lid, a second lid, a middle cover between the first lid and the second lid, and a hinge coupling together the first lid, the second lid, and the middle cover.

Data storage system enclosure covers

A system for selectively disallowing unwinding of a storage library robotic mechanism cable assembly in a direction that would otherwise allow a platform of the robotic mechanism to move downwardly via the force of gravity while at the same time allowing for winding up of the cable assembly and the platform, such as during shipping, manual access, replacement of the robotic mechanism, and/or the like. The system may include a ratchet pawl for engaging between adjacent teeth of a drive assembly of the robotic mechanism and an actuator for selectively moving or allowing for movement of the ratchet pawl into and out of the engaged position. In one embodiment, the system may include an electric switch or the like to sense when the pawl is engaged with the drive assembly.

Z-drive shipping lock for storage library robotic assembly

Utilities (e.g., systems, apparatuses, methods) that reduce robotic assembly contention in media element storage libraries by translating (e.g., displacing) a robot arm of a first robotic assembly mounted over a first storage array of a storage library away from a central reference plane as the robot arm is being pivoted into a first position adjacent the first storage array to allow a robot arm of a second robotic assembly to slide or otherwise move past the robot arm of the first robotic assembly, even when the robot arms of the first and second robot arms are disposed at the same height (e.g., along a z-axis) within the storage library. For instance, a pivot member of the robot arm may be mounted on a carriage that is configured to translate between the first and second storage arrays in response to the pivot member being pivoted about a pivot axis.

Simultaneous pivoting and translation of robot arm of storage library

System for simultaneous pivoting and translation of robot arm of storage library

Utilities that increase the volume of media elements that can be simultaneously loaded and/or unloaded into or from a storage library, facilitate mounting of media element magazines into a storage library, and limit access to an interior of a storage library by users during operation of robotics assemblies of the storage library. One disclosed utility includes a cartridge access port for use with a storage library that has a storage container that is pivotable (e.g., swingable) between at least first and second positions. In the first position, the storage container is adjacent an opening in the housing of the library for loading and unloading of media elements by a user into or from the container via the opening. After the storage container has swung into the second position, the storage container is spaced from the opening and faces the interior of the library for access by a robotics assembly.

Management of robotics assembly and cartridge access port of media element storage library

Embodiments include systems and methods for providing throughput increase and/or physical expansion of a data storage library. Some embodiments include multiple robotic assemblies, each having its own hand assembly, which are electrically and mechanically integrated for concurrent use in a single storage library environment for increased throughput. Other embodiments include an active vertical pass-through assembly that operates to ferry cartridges from one storage library environment to another, vertically adjacent storage library environment. Some such embodiments use existing robotic mechanisms of the libraries to exploit a shared slot through which vertical pass-through functionality can be realized. Other embodiments include an active horizontal pass-through assembly that operates to ferry cartridges from one storage library environment to another, horizontally adjacent storage library environment. Some such embodiments include a separate robotic mechanism that couples with each library and actively passes a cartridge among them and is adjustable to varying spans between the libraries.

Vertical pass-through for a data storage library

Embodiments of the invention include systems and methods for selective gripping and/or releasing of media cartridges using a robotic ratcheting gripper mechanism. Embodiments operate in context of a data storage library having a number of media cartridges physically located within slots of one or more magazines. A robot with a hand assembly uses a gripper mechanism to retrieve and ferry the cartridges between the magazines and one or more media drives. A novel gripper mechanism is provided that toggles between open and closed states according to movement of the gripper. In some embodiments, movement of a carriage from a retracted to an extended position extends the gripper mechanism and toggles its state, while movement of the carriage from the extended to the retracted position retracts the gripper mechanism while maintaining its state. Certain embodiments implement this functionality with simple mechanical components.

Ratcheting gripper for a storage library

Systems and methods are described for providing magnetic biasing of a carriage in context of linear guides. In one embodiment, a robotic mechanism is configured to travel on a platform assembly within a structural context. The platform assembly transports a carriage in a Z direction, and the carriage transports the robotic mechanism in an X direction. The carriage moves in the X direction along rails (e.g., and/or other types of linear guides) in a substantially floating or unbiased manner. For example, one or more alignment features on the carriage are in communication with the rails to allow the carriage to move relatively freely within an alignment region defined by the alignment features. When the carriage reaches its desired X location, magnetic features bias the carriage into a substantially accurate, secure, and repeatable position.

Linear rail magnetic biasing for a storage library

Systems and methods are described for providing a magnetic clutch to limit Z-directional motion of a mass (e.g., a carriage for transporting a robotic mechanism in context of a storage library). According to embodiments, the mass is suspended by cabling, and its Z-directional movement is controlled by a Z-drive assembly. The Z-drive assembly includes a drive gear made of a magnetic or conductive material, and the drive gear is in magnetic communication with a biasing magnet. Embodiments configured the biasing magnet with a particular magnetic moment and a position relative to the drive gear, so that the spinning of the drive gear induces magnetic currents that tend to counteract the motion of the gear. For example, in the event of power loss to the Z-drive assembly, magnetic clutching is used to limit or prevent motion of the mass under the force of gravity.

Magnetic Z-directional clutch

Multi-directional media element magazine for media element storage library

Systems and methods are described for fixed rotational positioning of a robotic hand assembly using mechanical wrist locking techniques. A wrist is configured to rotate the hand assembly and point grip components in a desired direction (e.g., for pick and place operations). Tolerances of components of the wrist can accumulate to manifest rotational positioning error. Embodiments include wrist locking techniques for locking the wrist in a desired rotational position. Some implementations couple grip components with wrist lock components in such a way that movement of the grip components causes the wrist lock assembly automatically to move between locked and unlocked states. For example, retracting the grip components pushes a wrist lock latch into an unlocked position (allowing the wrist to rotate). Extending the grip components allows the latch to move to a locked position where it interlocks with an alignment feature to lock the wrist into an accurate, predetermined angle.
