  • Patent number: 10387328
    Abstract: An apparatus, system, and method are disclosed for managing a non-volatile storage medium. A storage controller receives a message that identifies data that no longer needs to be retained on the non-volatile storage medium. The data may be identified using a logical identifier. The message may comprise a hint, directive, or other indication that the data has been erased and/or deleted. In response to the message, the storage controller records an indication that the contents of a physical storage location and/or physical address associated with the logical identifier do not need to be preserved on the non-volatile storage medium.

  • Publication number: 20180284707
    Abstract: A dispatch optimization system leverages ambient and market forecast data as well as asset performance and parts-life models to generate recommended operating schedules for gas turbines or other power-generating plant assets that substantially maximize profit while satisfying parts-life constraints. The system generates operating profiles that balance optimal peak fire opportunities with optimal cold part-load opportunities within a maintenance interval or other operating horizon. During real-time operation of the assets, the optimization system can update the operating schedule based on actual market, ambient, and operating data. The system provides information that can assist operators in determining suitable conditions in which to cold part-load or peak-fire the assets in an optimally profitable manner without violating target life constraints.

  • Publication number: 20170249242
    Abstract: In various embodiments, an apparatus, system, and method may increase data integrity in a redundant storage system. In one embodiment, a request is received for data stored at a storage system having a plurality of storage elements, where one or more of the plurality of storage elements include parity information. A determination is made that one of the plurality of storage elements is unavailable, the unavailable storage element being a functional storage element and including at least a portion of the data. Responsive to the determination, the data is reconstructed based on at least a portion of the parity information and data from one or more of the plurality of storage elements other than the unavailable storage element; a response is provided to the request such that the response includes the reconstructed data.

  • Patent number: 9734086
    Abstract: The invention includes a proxy request receiver module and a proxy request command module. The proxy request receiver module executes on a designated command proxy host and receives a proxy request from a requesting host. The requesting host is one of two or more hosts. Each of the hosts executes an operating system independent from the other hosts and a shared device. One of the hosts is designated as the command proxy host. A system bus connects the hosts and shared device. The proxy request includes a control request to be executed by the shared device sufficient to configure the shared device for a data transfer between the requesting host and shared device independent of the command proxy host. The control request is free of data. The proxy request command module transmits the control request to the shared device.

  • Publication number: 20170147241
    Abstract: An apparatus, system, and method are disclosed for efficiently managing commands in a solid-state storage device that includes a solid-state storage arranged in two or more banks. Each bank is separately accessible and includes two or more solid-state storage elements accessed in parallel by a storage input/output bus. The solid-state storage includes solid-state, non-volatile memory. The solid-state storage device includes a bank interleave that directs one or more commands to two or more queues, where the one or more commands are separated by command type into the queues. Each bank includes a set of queues in the bank interleave controller. Each set of queues includes a queue for each command type. The bank interleave controller coordinates among the banks execution of the commands stored in the queues, where a command of a first type executes on one bank while a command of a second type executes on a second bank.

  • Patent number: 9606914
    Abstract: An apparatus, system, and method are disclosed for allocating non-volatile storage. The storage device may present a logical address, which may exceed a physical storage capacity of the device. The storage device may allocate logical capacity in the logical address space. An allocation request may be allowed when there is sufficient unassigned and/or unallocated logical capacity to satisfy the request. Data may be stored on the non-volatile storage device by requesting physical storage capacity. A physical storage request, such as a storage request or physical storage reservation, when there is sufficient available physical storage capacity to satisfy the request. The device may maintain an index to associate logical identifiers (LIDs) in the logical address space with storage locations on the storage device. This index may be used to make logical capacity allocations and/or to manage physical storage space.

  • Patent number: 9600184
    Abstract: An apparatus, system, and method are disclosed for coordinating storage requests in a multi-processor/multi-thread environment. An append/invalidate module generates a first append data storage command from a first storage request and a second append data storage command from a second storage request. The storage requests overwrite existing data with first and second data including where the first and second data have at least a portion of overlapping data. The second storage request is received after the first storage request. The append/invalidate module updates an index by marking data being overwritten as invalid. A restructure module updates the index based on the first data and updates the index based on the second data. The updated index is organized to indicate that the second data is more current than the first data regardless of processing order. The modules prevent access to the index until the modules have completed updating the index.

  • Patent number: 9442844
    Abstract: A storage layer for a non-volatile storage device presents a large, logical address space having a logical capacity that may exceed the storage capacity of the non-volatile storage device. The storage layer implements persistent storage operations within the logical address space; storage operations performed within the logical address space may be persisted on the non-volatile storage device. The storage layer maintains storage metadata to allocate ranges of the logical address space to storage entities. The storage layer provides for allocation of contiguous logical address ranges, which may be implemented by segmenting logical identifiers into a first portion referencing storage entities, and a second portion referencing storage entity offsets. The storage layer persists data on the non-volatile storage device in a sequential, log-based format.
