摘要： An apparatus, system, and method are disclosed for data management. The method includes writing data in a sequential log structure. The method also includes receiving a time sequence request from a client. The method further includes servicing the time sequence request based on a temporal order of the data in the sequential log structure.

摘要： Apparatuses, systems, and methods are disclosed for snapshots of a non-volatile device. A method includes writing data in a sequential log structure for a non-volatile device. A method includes marking a point, in a sequential log structure, for a snapshot of data. A method includes preserving a logical-to-physical mapping for a snapshot based on a marked point and a temporal order for data in a sequential log structure.

摘要： 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.

摘要： 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.
摘要翻译： 数据服务模块通过在一个或多个存储设备上存储数据并且将与请求相关的信息附加到单独的元数据日志来响应于请求来执行日志存储操作。 元数据日志的日志顺序可以对应于接收请求的顺序，而不管将请求的数据写入存储设备的顺序如何。 请求可以对应于逻辑地址空间的标识符。 数据服务模块实现任意到任何翻译层，其被配置为将逻辑地址空间的标识符映射到所存储的数据。 虚拟化模块可以包括元数据管理模块，该元数据管理模块被配置为通过将聚合的检查点条目附加到元数据日志来检查点翻译层元数据。 数据服务模块可以利用逻辑标识符和底层存储位置之间的转换层来有效地实现逻辑操作操作。
