摘要: Compressed storage management includes assigning a selection priority and a priority level to multiple data units stored in an uncompressed portion of a storage resource. The management can further include compressing data units and storing the compressed data units in a compressed portion of the storage resource. The data units in the compressed portion are stored in regions, which each store data units having the same selection priority or the same selection priority level.

摘要: In accordance with one or more aspects, compressed storage management in a system includes determining which of multiple data units stored in an uncompressed portion of the storage resource are to be compressed and stored in a compressed portion of the storage resource. The management can further include returning one or more regions of the compressed portion for use in the uncompressed portion in response to storage resource pressure in the system, as well as compacting regions in the compressed portion to fill empty gaps in the compressed portion.

摘要: Embodiments of the invention provide techniques for managing cache metadata providing a mapping between addresses on a storage medium (e.g., disk storage) and corresponding addresses on a cache device at data items are stored. In some embodiments, cache metadata may be stored in a hierarchical data structure comprising a plurality of hierarchy levels. Only a subset of the plurality of hierarchy levels may be loaded to memory, thereby reducing the memory “footprint” of cache metadata and expediting the process of restoring the cache metadata during startup operations. Startup may be further expedited by using cache metadata to perform operations associated with reboot. Thereafter, as requests to read data items on the storage medium are processed using cache metadata to identify addresses at which the data items are stored in cache, the identified addresses may be stored in memory. When the computer is later shut down, instead of having to transfer the entirety of the cache metadata from memory to storage, only the subset of the plurality of hierarchy levels and/or the identified addresses previously loaded to memory may be transferred (e.g., to the cache device), thereby expediting the shutdown of the computer.
摘要翻译: 本发明的实施例提供了用于管理提供存储介质(例如,磁盘存储)上的地址之间的映射以及数据项上的高速缓存设备上的相应地址的缓存元数据的技术。 在一些实施例中,高速缓存元数据可以存储在包括多个层次级别的分层数据结构中。 可以仅将多个层次级别的子集加载到存储器,从而减少高速缓存元数据的存储器“占用空间”,并且加快在启动操作期间恢复高速缓存元数据的过程。 通过使用缓存元数据来执行与重新启动相关的操作,可以进一步加快启动。 此后,当使用高速缓存元数据来处理读取存储介质上的数据项的请求时,识别数据项存储在高速缓存中的地址,所识别的地址可被存储在存储器中。 当计算机稍后关闭时,不是必须将整个高速缓存元数据从存储器传送到存储器,所以只有先前加载到存储器的多个层次级别和/或已识别的地址的子集可以被传送(例如, 缓存设备),从而加速计算机的关闭。

摘要: Embodiments of the invention provide techniques for ensuring that the contents of a non-volatile memory device may be relied upon as accurately reflecting data stored on disk storage across a power transition such as a reboot. For example, some embodiments of the invention provide techniques for determining whether the cache contents and/or or disk contents are modified during a power transition, causing cache contents to no longer accurately reflect data stored in disk storage. Further, some embodiments provide techniques for managing cache metadata during normal (“steady state”) operations and across power transitions, ensuring that cache metadata may be efficiently accessed and reliably saved and restored across power transitions.
