    摘要： One embodiment is directed to the deletion of content units from a storage system. When a content unit is deleted, a reflection may be created and stored on the storage system. The reflection identifies the deleted content unit and may include additional information, such as a portion of the content of the content unit and audit information regarding the deletion of the content unit.

    摘要： One aspect involves mounting a file system stored on a CAS system. The file system has a directory structure that includes a plurality of directories arranged in a hierarchy and including a root directory at the top of the hierarchy. Each of the directories is represented by a content unit stored on the CAS system, the content unit having a content address that is computed based, at least in part, on at least a portion of the content of the content unit. The file system is mounted by specifying the content address of the content unit that represents the root directory and determining the file system to be mounted based on the content address of the content unit that represents the root directory.

    摘要： In one aspect, two ways of accessing a content unit stored on a CAS are provided, wherein the content unit has a content address that is computed based, at least in part, on at least a portion of its content. A first interface is provided to a file system in which the content unit is logically stored as a logical unit identified by a logical identifier, wherein the content unit is accessed in response to a request to the first interface to access the logical unit and identifying the content unit via the logical identifier. A second interface is provided through which the content unit can be accessed via the content address, wherein the content unit is accessed in response to a request to the second interface to access the content unit and identifying the content unit by the content address.

    摘要： Caching techniques for use in a computer system comprising a core and at least one edge device. The core comprises at least one object addressable storage (OAS) system that stores a plurality of content units and provides an interface that enables content units to be accessed via object identifiers. The at least one edge device is configured to access at least some of the content units. At least one cache is configured to be disposed logically between the core and the at least one edge device and to temporarily store a subset of the content units. The at least one cache is further configured to have a limit on a maximum number of content units that can be stored on the at least one cache simultaneously.

    摘要： Caching techniques for use in a computer system comprising a core and at least one edge device. The core comprises at least one object addressable storage system. At least one cache is disposed logically between the core and the at least one edge device. The cache has a prefetch policy that selects from among the content units based upon at least one prefetch criterion selected from the group consisting of: a source that wrote an evaluated content unit; a size of an evaluated content unit; a content type of an evaluated content unit; when the prefetch is performed subsequent to a request to access at least one of the plurality of content units, an identity of the requestor; when the prefetch is performed subsequent to a request to access at least one of the content units stored at a first time, proximity of a time at which an evaluated content unit was stored relative to the first time; and metadata written with the evaluated content unit.
