    • A boat trailer step assist includes a first and second support arm in pivotal relation to one another which provide steps that assist a user in entering or exiting a boat when trailered or in the process of being trailered. The support arms are arranged at an angle relative to the trailer tongue, with the first step at the level of the trailer tongue. When not in use, the second support arm pivots downward for compact stowage. When deployed, the support arms are in alignment with one another. A grab handle may be provided to assist the user in climbing or descending the steps.

    • A clone splitting technique enables efficient online splitting of blocks shared between a parent virtual volume (vvol) and a clone in accordance with a shared block splitting procedure executing on a storage system. Online splitting of shared blocks denotes allowing execution of read/write operations directed to the clone, as well as to the parent vvol, as the shared blocks are split. The clone splitting technique removes any connection between a clone and its parent vvol, thereby allowing the clone to be used as a first-class volume. Moreover, the technique removes such connection while allowing both the clone and parent vvol to remain available online and writeable (accessible) to clients during the shared block splitting procedure.
    • 克隆分割技术使得能够根据在存储系统上执行的共享块分割过程在父虚拟卷(vvol)和克隆之间共享的块的有效在线拆分。 共享块的在线拆分表示允许执行针对克隆的读/写操作以及父vvol,因为共享块被拆分。 克隆分割技术可以删除克隆与其父vvol之间的任何连接,从而允许将克隆用作一级卷。 此外,该技术消除了这种连接,同时允许克隆和父vvol在共享块分割过程期间在线保持可用并且可写(可访问)到客户端。

    • A storage system is provided that implements a file system configured to optimize the amount of readahead data retrieved for each read stream managed by the file system. The file system relies on various factors to adaptively select an optimized readahead size for each read stream. Such factors may include the number of read requests processed in the read stream, an amount of client-requested data requested in the read stream, a read-access style associated with the read stream, and so forth. The file system is also configured to minimize cache pollution by adaptively selecting when readahead operations are performed for each read stream and determining how long each read stream's retrieved data is retained in memory.

    • A storage system implements a storage operating system configured to concurrently perform speculative readahead for a plurality of different read streams. Unlike previous implementations, the operating system manages a separate set of readahead metadata for each of the plurality of read streams. Consequently, the operating system can “match” a received client read request with a corresponding read stream, then perform readahead operations for the request in accordance with the read stream's associated set of metadata. Because received client read requests are matched to their corresponding read streams on a request-by-request basis, the operating system can concurrently perform readahead operations for multiple read streams, regardless of whether the read streams' file read requests are received by the storage system in sequential, nearly-sequential or random orders. Further, the operating system can concurrently perform speculative readahead for the plurality of different read streams, even when the read streams employ different readahead algorithms. The invention may be implemented by file-based or block-based storage systems, or combinations thereof.
    • 存储系统实现存储操作系统,该存储操作系统被配置为同时对多个不同的读取流执行推测性的预读。 与先前的实现不同,操作系统管理多个读取流中的每一个的单独的一个先行元数据集。 因此,操作系统可以将接收到的客户端读取请求与对应的读取流“匹配”,然后根据读取流的相关元数据集执行针对请求的读取头部操作。 由于接收到的客户端读取请求在逐个请求的基础上与其对应的读取流匹配,所以操作系统可以同时对多个读取流执行预读操作,而不管读取流的文件读取请求是否被存储系统接收 在顺序,几乎顺序或随机的订单。 此外,即使当读取流采用不同的预读算法时,操作系统也可以并行地执行多个不同读取流的推测性预读。 本发明可以通过基于文件或基于块的存储系统或其组合来实现。

    • A cloning technique enables efficient and substantially instantaneous creation of a clone that is a writable copy of a “parent” virtual volume (vvol) in an aggregate of a storage system. A base snapshot is provided from the parent vvol. In addition, a new vvol is created, along with a new file system identifier, a new subdirectory in the aggregate and a new storage label file. The new vvol is embodied as a clone and comprises an appropriately sized container file, wherein initially the container file has no data. Moreover, a volume information (volinfo) block for the clone is created that is a slightly modified version of the volinfo block from the base snapshot; the modified volinfo block is written to the container file. The clone is then instantiated by loading a file system associated with the new vvol onto the clone and bringing the clone “online”.
    • 克隆技术能够有效地并且基本上即时创建作为存储系统的聚合中的“父”虚拟卷(vvol)的可写拷贝的克隆。 从父vvol提供基本快照。 此外,还创建了一个新的vvol,以及新的文件系统标识符,聚合中的新子目录和新的存储标签文件。 新的vvol被实现为克隆并且包括适当大小的容器文件,其中最初容器文件没有数据。 此外,创建克隆的卷信息(volinfo)块,其是来自基本快照的volinfo块的稍微修改的版本; 修改后的volinfo块被写入容器文件。 然后通过将与新vvol相关联的文件系统加载到克隆并将克隆“联机”来实例化克隆。
