摘要： Aspects of the invention relate to sharing content stored on an object addressable storage (OAS) system among a plurality of users of the OAS system and authenticating users to an OAS system. In some embodiments, a user may store content units on the OAS system and control access by other users to these content units. In some embodiments, when a user grants one or more other users access to a content unit stored on the OAS system, the OAS system may send a notification of grant of access to the other user(s).
摘要翻译：本发明的方面涉及在OAS系统的多个用户之间共享存储在对象可寻址存储（OAS）系统上的内容，并向OAS系统认证用户。在一些实施例中，用户可以在OAS系统上存储内容单元并且控制其他用户对这些内容单元的访问。在一些实施例中，当用户授权一个或多个其他用户访问存储在OAS系统上的内容单元时，OAS系统可以向另一个用户发送授权访问的通知。

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 edge device. The cache has a prefetch policy that selects from among the content units based upon at least one prefetch criterion. The prefetch policy imposes a limit on at least one prefetch operation. The limit is selected from the group consisting of: a total number of content units to be prefetched; a time range during which content units were stored to qualify as prefetch candidates; and a total volume of content to be prefetched.

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 replacement policy that selects from among the content units in the cache based upon at least one replacement criterion selected from the group consisting of: an identity of a source that wrote an evaluated content unit; when the replacement is performed subsequent to a request to access at least one content unit, an identity of a requestor that issued the request; a size of an evaluated content unit; a content type of an evaluated content unit; and when metadata was written along with an evaluated content unit, the substance of the metadata.

摘要： One embodiment is a system for locating content on a storage system, in which the storage system provides a location hint to the host of where the data is physically stored, which the host can resubmit with future access requests. In another embodiment, an index that maps content addresses to physical storage locations is cached on the storage system. In yet another embodiment, intrinsic locations are used to select a storage location for newly written data based on an address of the data. In a further embodiment, units of data that are stored at approximately the same time having location index entries that are proximate in the index.

摘要： One embodiment is a method and apparatus for modifying retention periods in a storage system, in which previously defined retention periods for units of data may be reduced. In another embodiment, the retention period of a unit of data may be modified in response to the occurrence of an event by renewing previously defined retention periods until the occurrence of the event is detected. If the occurrence of the event is detected, a retention period associated with that event may be established for the unit of data. In yet another embodiment, retention classes are used to define retention periods for units of data so that the retention period of a unit of data may be modified without modifying the unit of data itself. In a further embodiment, a request to the storage system to reduce a retention period includes authentication information that the storage system may use to verify the request.

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 embodiment of the invention, a utility may be installed (e.g., by a system administrator) on a storage system. The utility may read content units on the storage system that are stored in one data format, and convert the content units to a second data format. In one embodiment, in response to a read request for a content unit, a data format in which to return the content unit may be selected and the content unit may be returned in that data format. In another embodiment, mapping information may be created that specifies in which data format a content unit should be returned in response to a request for the content unit. The mapping information may be stored either on the storage system that stores the content unit, the computer requesting access to the content unit, or any other computer or device in the computer system.
摘要翻译：在本发明的一个实施例中，可以在存储系统上安装实用程序（例如由系统管理员）。实用程序可以读取以一种数据格式存储的存储系统上的内容单元，并将内容单元转换为第二数据格式。在一个实施例中，响应于对内容单元的读取请求，可以选择其中返回内容单元的数据格式，并且可以以该数据格式返回内容单元。在另一个实施例中，可以创建映射信息，该映射信息指定响应于对内容单元的请求而应当返回内容单元的哪个数据格式。映射信息可以存储在存储内容单元的存储系统上，请求访问内容单元的计算机或计算机系统中的任何其他计算机或设备。
