摘要： Embodiments are disclosed relating to garbage collecting storage blocks in a storage device. In one embodiment, data is selected for relocation from a storage block in a storage device during reclaiming of the storage block. The data may be selected based on metadata that identifies whether data is valid at a time when the reclaiming is initiated. In some embodiments, prior to relocating data from the storage block, the metadata is captured from a data structure that identifies whether data on the storage device is valid. In one embodiment, a determination of whether the selected data has become invalid due to other data that is stored during the reclaiming is made. In some embodiments, in response to determining that the selected data has become invalid, the selected data is specified as invalid in the data structure.

摘要： A cache automation module detects the deployment of storage resources in a virtual computing environment and, in response, automatically configures cache services for the detected storage resources. The automation module may detect new storage resources by monitoring storage operations and/or requests, by use of an interface provided by virtualization infrastructure, and/or the like. The cache automation module may deterministically identify storage resources that are to be cached and automatically caching services for the identified storage resources.

摘要： A virtual storage layer (VSL) for a non-volatile storage device presents a logical address space of a non-volatile storage device to storage clients. Storage metadata assigns logical identifiers in the logical address space to physical storage locations on the non-volatile storage device. Data is stored on the non-volatile storage device in a sequential log-based format. Data on the non-volatile storage device comprises an event log of the storage operations performed on the non-volatile storage device. The VSL presents an interface for requesting atomic storage operations. Previous versions of data overwritten by the atomic storage device are maintained until the atomic storage operation is successfully completed. Data pertaining to a failed atomic storage operation may be identified using a persistent metadata flag stored with the data on the non-volatile storage device. Data pertaining to failed or incomplete atomic storage requests may be invalidated and removed from the non-volatile storage device.
