Abstract: A technique provisions a computerized device with a main operating system. The technique involves loading, while the computerized device operates as a preboot execution environment (PXE) protocol client, a limited boot image from a PXE server over a network (e.g., booting the limited boot image using the trivial file transfer protocol or TFTP). The technique further involves executing the limited boot image loaded from the PXE server to operate the computerized device as an advanced protocol provisioned client. The technique further involves downloading, while the computerized device executes the limited boot image to operate as the advanced protocol provisioned client, the main operating system into local memory from an operating system server over the network (e.g., booting the main operating system using the file transfer protocol or FTP). The computerized device may store a copy of the main operating system in a local non-volatile cache if available.

Abstract: A technique assigns tasks to workers within a work area. The technique utilizes electronic circuitry which can be disposed at a single location (e.g., a server), or distributed among multiple locations (e.g., in the cloud). The technique involves receiving task entries which (i) identify tasks in need of attention and (ii) define task requirements for performing the tasks. The technique further involves generating task assignments based on matching the task entries to worker profiles which (i) identify workers who are available for task assignment and (ii) define worker characteristics of the workers. The technique further involves providing the task assignments to the workers while the workers are distributed among different locations within the work area. The task assignments direct the workers to perform the tasks identified by the task entries in accordance with the task requirements defined by the task entries.

Abstract: Embodiments include systems and methods for controlling power distribution and supply across independently powered modules in a storage library. Embodiments operate in context of a data storage library having a base module and one or more expansion modules. Each expansion module is independently powered, and each is in communication with the base module via a powered data communications network. In some embodiments, when the base module power supply is on, a base controller in the base module provides network power over the powered data communications network. The network power causes expansion controllers in each expansion module to boot up and power on the power supplies of their respective modules. When the base module is powered down, power is no longer available to the expansion controllers, and the respective power supplies can be hard-coded to shut down automatically under that condition.

Abstract: Track anomalies are detected by measuring track impedance. A robotic device is moved along the track. A conductor on the track is contacted with a pair of pickups moved by the robotic device. Track health is determined based on impedance sensed between the pickups.

Abstract: The present invention provides removable-unit storage modules, which can be combined into a network. The storage modules comprise storage cells arranged in a rule based structured configuration, and robotic hands to which move along tracks in order to retrieve objects from the storage cells. In one embodiment, the storage cells are used to contain data storage units. Several modules can be combined into a network by means of bridge tracks which connect the tracks of different modules, allowing the robotic hands to move between modules. The bridge tracks can be dynamically connected and disconnected from the modules, allowing the network configuration to change according to user needs. The individual modules are mobile and can be transported to other locations and connected with other removable-unit storage networks.

Abstract: An automated library system having multiple storage cells for storing multiple data cartridges. Rails are provided adjacent to the storage cells to guide one or more robots among the storage cells. Primary coils are disposed proximate the rails. A power supply produces an alternating current in the primary coils. One or more magnetic cores are mounted on each robot. Each magnetic core is adjustable to form a normally gap-less closed magnetic path, and a gapped magnetic path when transitioning between primary coils. Alternating currents in the primary coils induce secondary alternating currents in secondary coils wound around the magnetic cores. The secondary alternating currents are controlled and converted into mechanical movement that include loading and unloading the data cartridges to and from the robots, and moving the data cartridges along the rails.

Abstract: Track anomalies in an automated storage library are detected by transmitting a track health signal from one portion of the track. The presence of a track anomaly is determined based on any reception of the transmitted signal at another portion of the track.

Abstract: Power strip health is monitored by detecting power supplied through the power strip as sensed by a robotic device. An indication of power is sensed from the power strip with a first power pickup and a second power pickup. The second power pickup is located on the robotic device away from the first power pickup along a direction of travel of the robotic device. A determination is made that the difference between the power sensed with the first power pickup and the power sensed with the second power pickup exceeds a threshold. A power strip failure is determined based on this difference.

Abstract: Brush failure detection on a robotic device for use with a data storage library is accomplished through the use of two brushes drawing power from the same conductor. For example, each brush conducts electrical current between the robotic device and a conductor. Electronics determine operating status of each brush based on a measurement of the difference in current conducted through each brush in the pair of brushes.

Abstract: Operations along a track suffering some track anomaly are resumed by bridging the anomaly with a robotic device. The track supports operation of a plurality of robotic devices. The anomaly prevents the flow of electrical current from reaching an affected section of the track. A robotic device is moved to the anomaly so that electrical current flows into a first pickup on the robotic device located on one side of the anomaly and out of a second pickup on the robotic device located on another side of the anomaly.
