    Abstract: An atomic storage module may be configured to implement atomic storage operation directed to a first set of identifiers in reference to a second, different set of identifiers. In response to completing the atomic storage operation, the atomic storage module may move the corresponding data to the first, target set of identifiers. The move operation may comprise modifying a logical interface of the data. The move operation may further include storing persistent metadata configured to bind the data to the first set of identifiers.

    Abstract: An aggregation module combines a plurality of logical address spaces to form a conglomerated address space. The logical address spaces comprising the conglomerated address space may correspond to different respective storage modules and/or storage devices. An atomic aggregation module coordinates atomic storage operations within the conglomerated address space, and which span multiple storage modules. The aggregation module may identify the storage modules used to implement the atomic storage request, assign a sequence indicator to the atomic storage request, and issue atomic storage requests (sub-requests) to the storage modules. The storage modules may be configured to store a completion tag comprising the sequence indicator upon completing the sub-requests issued thereto. The aggregation module may identify incomplete atomic storage requests based on the completion information stored on the storage modules.

    Abstract translation: 聚合模块组合多个逻辑地址空间以形成集合地址空间。 包含集合地址空间的逻辑地址空间可以对应于不同的各自的存储模块和/或存储设备。 原子聚合模块协调集合地址空间内的原子存储操作，并跨越多个存储模块。 聚合模块可以识别用于实现原子存储请求的存储模块，为原子存储请求分配序列指示符，并向存储模块发出原子存储请求（子请求）。 存储模块可以被配置为在完成向其发出的子请求时存储包括序列指示符的完成标签。 聚合模块可以基于存储在存储模块上的完成信息来识别不完整的原子存储请求。

    Abstract: Techniques are disclosed relating to writing data atomically to one or more recording media. In one embodiment, a request is received to perform an atomic write for a set of data. Responsive to the request, the set of data is written across a plurality of storage units including storing metadata at a dedicated location within at least one of the plurality of storage units. The metadata is usable to determine whether the writing completed successfully. In some embodiments, the request is received from an application that has been assigned an address range of the plurality of storage units. In such an embodiment, the address range is accessible to the application for storing data, and the dedicated location resides outside of the address range. In one embodiment, the metadata specifies an address range where the set of data was written and a sequence number.

    Abstract: A storage layer is configured to implement efficient open-close consistency operations. Open close consistency may comprise preserving the original state of a file until the file is closed. The storage layer may be configured to clone a file in response to a file open request. Cloning the file may comprise referencing file data by two separate sets of identifiers. One set may be configured to reflect file modifications, and the other set may be configured to preserve the original state of the file. Subsequent operations configured to modify the file may be performed in reference to one of the sets of identifiers, while the storage layer provides access to the unmodified file through the other set of identifiers. Closing the file may comprise merging the sets of identifiers according to a merge policy.
