Abstract: A storage controller may be configured to assess the reliability of a solid-state storage medium. The storage controller may be further configured to project, forecast, and/or estimate storage reliability at a future time. The projection may be based on a currently reliability metric of the storage and a reliability model. The portions or sections of the solid-state storage media may be retired in response the projected reliability metric failing to satisfy a reliability threshold. The reliability threshold may be based on data correction and/or reconstruction characteristics. The projected reliability metrics of a plurality of erase blocks of a storage division may be combined, and one or more of the erase blocks may be retired in response to determining that the combined reliability metric projection fails to satisfy the reliability threshold.

Abstract: A storage layer is configured to store data at respective offsets within storage units of a storage device. Physical addresses of the data may be segmented into a first portion identifying the storage unit in which the data is stored, and a second portion that indicates the offset of the data within the identified storage unit. An index of the data offsets (e.g., second portions of the physical addresses) may be persisted on the storage device. The first portion of the address may be associated with logical addresses of the data in a forward index. The forward index may omit the second portion of the physical addresses, which may reduce the memory overhead of the index and/or allow the forward index to reference larger storage devices. Data of a particular logical address may be accessed using the first portion of the physical address maintained in the forward index, and the second portion of the media address stored on the storage device.
Abstract translation: 存储层被配置为在存储设备的存储单元内的相应偏移处存储数据。 数据的物理地址可以被分割成识别其中存储数据的存储单元的第一部分，以及指示所识别的存储单元内的数据的偏移的第二部分。 数据偏移的索引（例如，物理地址的第二部分）可以被持久存储在存储设备上。 地址的第一部分可以与前向索引中的数据的逻辑地址相关联。 前向索引可以省略物理地址的第二部分，这可以减少索引的存储器开销和/或允许前向索引引用较大的存储设备。 可以使用保存在前向索引中的物理地址的第一部分和存储在存储设备上的媒体地址的第二部分来访问特定逻辑地址的数据。

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 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: 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.
