    Abstract: A data services module performs log storage operations in response to requests by storing data on one or more storage devices, and appending information pertaining to the requests to a separate metadata log. A log order of the metadata log may correspond to an order in which the requests were received, regardless of the order in which data of the requests are written to the storage devices. The requests may correspond to identifiers of a logical address space. The data services module implements an any-to-any translation layer configured to map identifiers of the logical address space to the stored data. The virtualization module may include a metadata management module configured to checkpoint the translation layer metadata by, inter alia, appending aggregate, checkpoint entries to the metadata log. The data services module may leverage the translation layer between the logical identifiers and underlying storage locations to efficiently implement logical manipulation operations.

    Abstract: Techniques are disclosed relating to storing translations in memory that are usable to access data on a recording medium. In one embodiment, a request is sent for a memory allocation within a non-pageable portion of a memory in a computer system. Responsive to the request, allocated memory is received. Translations usable to map logical addresses to physical addresses within a storage device are stored within the allocated memory. In some embodiments, the translations are usable to access an area within the storage device used to store pages evicted from the memory. In one embodiment, a size of the memory allocation is determined based on a size of the area. In another embodiment, a size of the memory allocation is determined based on a size of a partition including the area. In some embodiments, the storage device is a solid-state storage array.

    Abstract: A cache log module stores an ordered log of cache storage operations sequentially within the physical address space of a non-volatile storage device. The log may be divided into segments, each comprising a set of log entries. Data admitted into the cache may be associated with respective log segments. Cache data may be associated with the log segment that corresponds to the cache storage operation in which the cache data was written into the cache. The backing store of the data may be synchronized to a particular log segment by identifying the cache data pertaining to the segment (using the associations), and writing the identified data to the backing store. Data lost from the cache may be recovered from the log by, inter alia, committing entries in the log after the last synchronization time of the backing store.
