摘要： A network storage server system includes a distributed object store, a presentation layer, a metadata subsystem, and a content management subsystem. The object store has no namespace and provides location-independent addressing of data objects. The presentation layer provides multiple interfaces for accessing data stored in the object store, including a NAS interface and a Web Service interface, and provides at least one namespace for accessing data via the NAS interface or the Web Service interface. The Web Service interface allows access to stored data via the namespace or without using the namespace (“raw object” access). The metadata subsystem stores user-specified and/or system-generated metadata relating to data objects and allows data objects to be identified and retrieved by searching on the metadata. The content management subsystem autonomously manages lifecycles of data objects according to user-specified policies, based on metadata associated with the data objects and tracked by the metadata subsystem.

摘要： A distributed object store in a network storage system uses location-independent global object identifiers (IDs) for stored data objects. The global object ID enables a data object to be seamlessly moved from one location to another without affecting clients of the storage system, i.e., “transparent migration”. The global object ID can be part of a multilevel object handle, which also can include a location ID indicating the specific location at which the data object is stored, and a policy ID identifying a set of data management policies associated with the data object. The policy ID may be associated with the data object by a client of the storage system, for example when the client creates the object, thus allowing “inline” policy management. An object location subsystem (OLS) can be used to locate an object when a client request does not contain a valid location ID for the object.
摘要翻译：网络存储系统中的分布式对象存储使用与存储的数据对象的位置无关的全局对象标识符（ID）。全局对象ID使数据对象无缝地从一个位置移动到另一个位置，而不会影响存储系统的客户端，即“透明迁移”。全局对象ID可以是多级对象句柄的一部分，其还可以包括指示存储数据对象的特定位置的位置ID，以及标识与数据对象相关联的一组数据管理策略的策略ID。策略ID可以由存储系统的客户端与数据对象相关联，例如当客户端创建对象时，从而允许“内联”策略管理。当客户机请求不包含对象的有效位置ID时，可以使用对象位置子系统（OLS）来定位对象。

摘要： A network storage server system includes a distributed object store and a metadata subsystem. The metadata subsystem stores metadata relating to the stored data objects and allows data objects to be located and retrieved easily via user-specified search queries. It manages and allows searches on at least three categories of metadata via the same user interface and technique. These categories include user-specified metadata, inferred metadata and system-defined metadata. Search queries for the metadata can include multi-predicate queries.

摘要： A network storage server system includes a presentation layer that presents multiple namespaces over the same data stored in an object store, allowing users to simultaneously access data over multiple protocols. The system supports object location independence of the stored data objects by introducing a layer of indirection between directory entries and storage locations of stored data objects. In one embodiment, the directory entry of a data object points to a redirector file that includes an object locator (e.g., an object handle or a global object ID) of the data object. The directory entries of data objects are stored in a directory namespace (e.g., NAS path namespace). In another embodiment, a global object ID of the data object is directly encoded within the directory entry of the data object.

摘要： Methods and systems are described comprising a plurality of nodes each comprising at least one processor and at least one storage device providing storage for the system along with an interconnect configured to establish connections between pairs of nodes. The nodes may be configured (e.g. programmed) to determine from a file identifier that identifies a particular file that a node desires to access, which of the plurality of nodes stores the desired file. The interconnect may then establish a connection between the node and the node storing the file to permit the node desiring access to access the file (e.g., read or write the file). Further, the system comprising the plurality of nodes (e.g., a cluster computing architecture) may be balanced or nearly balanced.
