摘要： Embodiments of the present invention enable dynamic repartitioning of data storage in response to one or more triggers. In embodiments, a trigger may be a user-initiated action, a system-generated action, and/or an inference based on storage usage parameters. Applications of the present invention are its use in embodiments of a storage management system comprising a file system manager and a volume manager, where the placement of data into a partition (data storage region) may be specified by matching one or more disk region placement data attributes assigned to data with corresponding disk region attributes. In embodiments, dynamic repartitioning comprises adjustment of the location of the boundary between adjacent disk partitions and, if necessary, rebalancing of the data stored within the partitions by identifying mismatched data and relocating it to the partition with which it is associated.

摘要： Techniques for universal cache management are described. In an example embodiment, a plurality of caches are allocated, in volatile memory of a computing device, to a plurality of data-processing instances, where each one of the plurality of caches is exclusively allocated to a separate one of the plurality of data-processing instances. A common cache is allocated in the volatile memory of the computing device, where the common cache is shared by the plurality of data-processing instances. Each instance of the plurality of data-processing instances is configured to: identify a data block in the particular cache allocated to that instance, where the data block has not been changed since the data block was last persistently written to one or more storage devices; cause the data block to be stored in the common cache; and remove the data block from the particular cache. Data blocks in the common cache are maintained without being persistently written to the one or more storage devices.

A common cache is allocated in the volatile memory of the computing device, where the common cache is shared by the plurality of data-processing instances. Each instance of the plurality of data-processing instances is configured to: indentify a data block in the particular cache allocated to that instance, where the data block has not been changed since the data block was last persistently written to one or more storage devices; cause the data block to be stored in the common cache; and remove the data block from the particular cache. Data blocks in the common cache are maintained without being persistently written to the one or more storage devices.
摘要翻译：描述了用于通用缓存管理的技术。在一个示例性实施例中，在计算设备的易失性存储器中将多个高速缓存分配给多个数据处理实例，其中多个高速缓存中的每一个高速缓存独占地分配给多个数据处理实例中的单独一个，处理实例。在计算设备的易失性存储器中分配公共高速缓存，其中公共高速缓存由多个数据处理实例共享。多个数据处理实例的每个实例被配置为：识别分配给该实例的特定高速缓存中的数据块，其中由于数据块最后持续写入一个或多个存储设备，数据块尚未改变; 使数据块存储在公共高速缓存中; 并从特定缓存中删除数据块。维持公用高速缓存中的数据块，而不会持续写入一个或多个存储设备。
