摘要： Client data corresponding to a single client can be stored. A decision to proceed with a defragmentation of two or more particular core groups can be determined. A destination core group to receive client data can be identified. At least one additional core group can be initiated to manage interim data write requests from the single client. Each of the two or more particular core groups can be closed to data write requests. A defragmentation of the two or more particular core groups can be performed by merging into the destination core group. The destination core group can be availed to data read and delete requests. The two or more fragmented core groups can be reallocated for other uses. The additional core groups continue to receive read and write requests. The destination core groups further can be merged and defragmented further.

摘要： Techniques are provided for implementing intelligent defragmentation in a storage system. A storage control system manages a logical address space of a storage volume. The logical address space is partitioned into a plurality of extents, wherein each extent comprises a contiguous block of logical addresses of the logical address space. The storage control system monitors input/output (I/O) operations for logical addresses associated with the extents, and estimates fragmentation levels of the extents based on metadata associated with the monitored I/O operations. The storage control system identifies one or more extents as candidates for defragmentation based at least on the estimated fragmentation levels of the extents.

摘要： A method for organizing a storage file is described in the embodiments of the present disclosure. The method includes: performing predetermination for organizing and scanning on a selected storage file to determine whether the selected storage file needs to be scanned for fragmentation and organized; and scanning the selected storage file for fragmentation and organizing the storage file, if it is determined that the selected storage file needs to be scanned for fragmentation and organized. Thereby, the time spent on organizing the file is reduced and the efficiency for organizing the file is improved.

摘要： Systems and methods for on-site filtering and prioritizing logged data prior to transmission to a support server are described. An analyzer application executing on the same system as a filesystem application may retrieve a core file dump in response to an unexpected behavior. An actively running thread at the time of the unexpected behavior may be identified, and thread relationship rules are used to generate a list of related threads based on sharing a common resource with the actively running thread. A relevance factor may be determined for each of the sub-components of the related threads based on a positioning within a hierarchical tree of the related threads. Log files from the sub-components may then be selected for a support file bundle, based on the relevance factors and the file sizes of the log files fitting within a size limit, then transmitted to the support server.

摘要： Unified management, automation, interoperability, and synchronization of virtual and physical device systems utilizing components of a no-code, event-driven edge computing platform on any device and/or across difference devices. In an embodiment, a system on a device accesses a first events dataset which represents a two-dimensional structure. Each row in the events dataset is processed by the system to create or update the state of a runtime dataset which represents a two-dimensional structure. The state of the runtime dataset comprises an instance of an event-defined system including event-defined processes. In an embodiment, the event-defined processes are executed by the system to process a second events dataset, wherein the execution of the event-defined processes further updates the state of the runtime dataset and may create one or more new events for processing.

摘要： Aspects directed towards data storage management are provided. In one aspect, a data storage system receives fragmentation level information from data storage devices, and host data from a host device to be stored in the data storage devices. Based on the received fragmentation level information, a target data storage device is selected from the data storage devices, and the host data is sent to the target data storage device. In another aspect, a data storage device determines threshold conditions that trigger a defragmentation process. For this aspect, a fragmentation level metric indicating a proximity of the data storage device to initiating the defragmentation process is calculated based on the threshold conditions and a current amount of data stored in a non-volatile memory (NVM). The fragmentation level metric is then sent to a storage management device.

摘要： A storage system is provided that performs a defragmentation operation or proactive garbage collection in its memory based on a command from a host. The command specifies which blocks in the memory should take part in the defragmentation operation by specifying a maximum amount of valid data that a block can have to qualify for defragmentation. That way, the storage system only performs defragmentation on those blocks that meet the validity criteria provided by the host. This can help improve performance of the storage system while reducing the degree of negative tradeoffs that may come with defragmentation or proactive garbage collection.
