    Abstract: Techniques are disclosed relating to determining statistics associated with the storage of data on a medium. In one embodiment, a computing system maintains a management statistic for a storage device, and uses the management statistic as a proxy for a workload statistic for a storage block within the storage device. In some embodiments, the storage block is a first storage block included within a second storage block of the storage device. In one embodiment, the management statistic is a timestamp indicative of when a write operation was performed for the second storage block; the workload statistic is a write frequency of the first storage block. In one embodiment, the management statistic is a number of read operations performed for the second storage block; the using includes deriving, based on the number of read operation, a read frequency for the first storage block as the workload statistic.

    Abstract: Apparatuses, systems, methods and computer program products are disclosed for auto-commit memory management. A method includes receiving a memory request from a client, such as a barrier request or a checkpoint request. The memory request is associated with a volatile memory buffer of a non-volatile recording device. The memory buffer may be configured to preserve data in the non-volatile recording device in response to a trigger. A method includes issuing a serializing instruction that flushes data from a processor complex to the memory buffer. A method includes determining completion of the serializing instruction flushing the data to the memory buffer.

    Abstract: Techniques are disclosed relating to handling snapshot data for a storage device. In one embodiment, a computing system maintains information that indicates the state of data associated with an application at a particular point in time. In this embodiment, the computing system assigns an epoch number to a current epoch, where the current epoch is an interval between the particular point in time and a future point in time. In this embodiment, the computing system writes, during the current epoch, a block of data to the storage device. In this embodiment, the writing the block of data includes storing the epoch number with the block of data.

    Abstract: Techniques are disclosed relating to reclaiming data on recording media. In one embodiment, an apparatus has a solid-state memory array including a plurality of blocks. The solid-state memory array may implement a cache for one or more storage devices. Respective operational effects are determined relating to reclaiming ones of the plurality of blocks. One of the plurality of blocks is selected as a candidate for reclamation based on the determined operational effects, and the selected block is reclaimed. In some embodiments, the determined operational effects for a given block indicate a number of write operations to be performed to reclaim the given block. In some embodiments, operational effects are determined based on criteria relating to assigned quality-of-service levels. In some embodiments, operational effects are determined based on information relating virtual storage units.

    Abstract: A cache and/or storage module may be configured to reduce write amplification in a cache storage. Cache layer write amplification (CLWA) may occur due to an over-permissive admission policy. The cache module may be configured to reduce CLWA by configuring admission policies to avoid unnecessary writes. Admission policies may be predicated on access and/or sequentiality metrics. Flash layer write amplification (FLWA) may arise due to the write-once properties of the storage medium. FLWA may be reduced by delegating cache eviction functionality to the underlying storage layer. The cache and storage layers may be configured to communicate coordination information, which may be leveraged to improve the performance of cache and/or storage operations.
