Abstract: An apparatus, system, and method are disclosed for storage address translation. The method includes storing, in volatile memory, a plurality of logical-to-physical mapping entries for a non-volatile recording device. The method includes persisting a logical-to-physical mapping entry from the volatile memory to recording media of the non-volatile recording device. The logical-to-physical mapping entry may be selected for persisting based on a mapping policy indicated by a client. The method includes loading the logical-to-physical mapping entry from the recording media of the non-volatile recording device into the volatile memory in response to a storage request associated with the logical-to-physical mapping entry.

Abstract: Apparatuses, systems, methods, and computer program products are disclosed for hybrid checkpointed memory. A method includes referencing data of a range of virtual memory of a host. The referenced data is already stored by a non-volatile medium. A method includes writing, to a non-volatile medium, data of a range of virtual memory that is not stored by the non-volatile medium. A method includes providing access to data of a range of virtual memory from a non-volatile medium using a persistent identifier associated with referenced data and written data.

Abstract: A storage layer may be configured to over-provision logical storage resources to objects. The storage layer may provision the resources in response to, inter alia, a request to open and/or create a zero-length file. The storage layer may be further configured to store data of the objects in a contextual format configured to associate the data with respective logical identifiers. The storage layer may determine an actual, storage size of the object based on the associations stored on the stored associations. Storage clients may rely on the storage layer to determine the size of the object and, as such, may defer and/or eliminate updates to persistent metadata.

Abstract translation: 可以将存储层配置为向对象过度提供逻辑存储资源。 尤其是响应于打开和/或创建零长度文件的请求，存储层可以提供资源。 存储层可以被进一步配置为以配置成将数据与相应的逻辑标识符相关联的上下文格式来存储对象的数据。 存储层可以基于存储在所存储的关联上的关联来确定对象的实际存储大小。 存储客户端可以依靠存储层来确定对象的大小，并且因此可以延迟和/或消除对持久性元数据的更新。

Abstract: Resources of an address space are managed in dynamically sized ranges, extents, sets, and/or blocks. The address space may be divided into regions, each corresponding to a different, respective allocation granularity. Allocating a block within a first region of the address space may comprise allocating a particular number of logical addresses (e.g., a particular range, set, and/or block of addresses), and allocating a block within a different region may comprise allocating a different number of logical addresses. The regions may be configured to reduce the metadata overhead needed to identify free address blocks (and/or maintain address block allocations), while facilitating efficient use of the address space for differently sized data structures.
