Abstract: A battery management system (BMS) controls lithium battery access on a utility vehicle. The BMS includes a battery interface that couples with a lithium battery, a load interface that couples with a set of loads of the utility vehicle, and control circuitry coupled with the battery interface and the load interface.

Furthermore, after the battery interface is mechanically reconnected to the load interface, the control circuitry maintains connection between the battery interface and the load interface to convey power from the lithium battery to the set of loads of the utility vehicle through the battery interface and the load interface.

The technique involves operating electronic circuitry of the utility vehicle in a normal operating mode in which the electronic circuitry charges the lithium battery to a normal charge level. The technique further involves, after operating the electronic circuity in the normal operating mode, transitioning the electronic circuitry from the normal operating mode to a storage mode in which the electronic circuitry is configured to set an amount of charge on the lithium battery to within a predefined storage range (or level) which is lower than the normal charge level. The technique further involves, in response to transitioning the electronic circuitry, adjusting the amount of charge on the lithium battery from an initial charge level which is outside the predefined storage range to an adjusted charge level which is within the predefined storage range.

Abstract: A method for managing metadata in a storage system is disclosed. The system includes a processor, a storage medium, a first metadata table that maps every data block's LBN to its unique content ID, and a second metadata table that maps every content ID to its PBN on the storage medium. During a data movement process, the processor is configured to determine the content ID of the data block and update its entry in the second metadata table without accessing the first metadata table. A method is also disclosed to reduce the size of the first metadata table. Only content ID is stored in the first metadata table and its LBN is determined by the metadata entry's relative position in the table. Metadata entries are stored in metadata blocks and deduplicated.

Abstract: Methods, systems, and computer readable media for backing up and restore a deployment on a cloud computing platform are described. A deployment on a cloud computing platform includes a set of virtual machines and corresponding disks. A deployment may include multiple subunits designated as deployment jobs. A respective job specification file specifies respective resources used by each deployment job. The resources include various scripts specifying actions to take before, during, and after a backup. A backup orchestrator, upon receiving a backup request for the deployment, executes the scripts in a pre-specified sequence ordered by script type. When a particular type of scripts executes, the corresponding script for each deployment job, if specified in the specification file to correspond to that type, executes. When all scripts of a particular type finish execution, scripts having a next type execute. Accordingly, the operations of backing up multiple deployment jobs are synchronized and orchestrated.
