摘要： Accordingly a method and interface allows an attribute data base used by an Information Manager to be quickly populated and accurately maintained. A single Bulk Attribute Retrieval Request triggers the primary storage device to collect object attribute information. The method allows for selective collection of objects and attributes by providing filters and attribute lists in the Requests. The Request may be used to provide an incremental scan with appropriate time stamp filtering. In addition, the size of the results can be controlled by the IM by eliminating attributes that are not of interest to the IM. The Request is advantageously issued over a FileMover interface, which is an HTTP connection, and encoded in XML, allowing the IM to easily customize the Request as desired.

摘要： A namespace server translates client requests for access to files referenced by pathnames in a client-server namespace into requests for access to files referenced by pathnames in a backend NAS network namespace. The namespace server also translates between different file access protocols. The namespace server may change the translation of a client-server network pathname from an old backend NAS network pathname to a new backend NAS network pathname for file migration without disruption to client access during file migration for load balancing or for a more appropriate service level. Client access can also be routed automatically and transparently to replicas in case of server or site failures. The namespace server may create the appearance of a virtual file system that contains multiple physical servers, a virtual share that contains physical shares from different servers, directories that contain files on different servers, and files that contain data from files on different servers.
摘要翻译：命名空间服务器将访问由客户机 - 服务器命名空间中的路径名引用的文件的客户端请求转换为访问由后端NAS网络命名空间中的路径名引用的文件的请求。命名空间服务器还可以在不同的文件访问协议之间进行转换。命名空间服务器可以将客户端 - 服务器网络路径名从旧的后端NAS网络路径名转换为用于文件迁移的新的后端NAS网络路径名，而不会在文件迁移期间客户端访问中断负载平衡或更适合的服务级别。客户端访问也可以在服务器或站点故障的情况下自动和透明地路由到副本。命名空间服务器可以创建包含多个物理服务器的虚拟文件系统的外观，包含来自不同服务器的物理共享的虚拟共享，包含不同服务器上的文件的目录以及包含来自不同服务器上的文件的数据的文件。

摘要： Extensions to the Fragment Mapping Protocol are introduced which protect a disk array from malicious client access by exporting file system access information to the storage device. FMP requests received at the storage device can be authorized at a block granularity prior to completion, thereby limiting the exposure of the disk array to malicious clients. Client authorizations can be cached at the storage device to enable the permissions to be quickly extracted for subsequent client accesses to pre-authorized volumes.
摘要翻译：引入片段映射协议的扩展，通过将文件系统访问信息导出到存储设备来保护磁盘阵列免受恶意客户端访问。可以在完成之前以块粒度授权在存储设备处接收到的FMP请求，从而限制磁盘阵列暴露于恶意客户端。客户端授权可以在存储设备上缓存，以便快速提取权限，以便后续客户端访问预授权卷。

摘要： A versioned file system comprises a set of structured data representations, such as XML. Each structured data representation corresponds to a “version,” and each version comprises a tree of write-once objects rooted at a root directory manifest. Each version in the versioned file system has associated therewith a “borrow window.” When it is desired to reconstruct the file system to a point in time (or, more generally, a given state), i.e., to perform a “restore,” it is only required to walk (use) a single structured data representation (a tree). During a restore, metadata is pulled back from the cloud first, so users can see the existence of needed files immediately. The remainder of the data is then pulled back from the cloud if/when the user goes to open the file. As a result, the entire file system (or any portion thereof) can be restored to a previous time nearly instantaneously. A “fast” restore is performed if an object being restored exists within a “borrow window” of the version from which the system is restoring. A version is pruned from the versioned file system by deleting all objects in the tree (associated with the version) that, at the time of pruning: (i) are not being lent to any other version within the borrow window of the version being pruned, and (ii) are not referenced in any other version whose borrow window is sufficiently large enough such that an object in the version could have been restored from that other version.

摘要： Managing file objects in a data storage system includes providing a plurality of metadata servers, each metadata server having information for only a subset of file objects in the storage system, each subset for each of the metadata servers being less than a total number of file objects for the system and includes providing at least one metadata location server, where an entity accessing a specific file object of the system determines which of the metadata servers contains data for the specific file object by first accessing the at least one metadata location server. Information for the subset of file objects may include a table having file identifiers and metadata location information. The metadata location information may point to data storage for a metadata object for a file.

摘要： A method of data sharing among multiple entities is provided. Each entity exports to a data store a structured data representation comprising a versioned file system local to that entity. The method begins by forming a sharing group that includes two or more entities. Sharing of the structured data representations by members of the sharing group is enabled. The filers use a single distributed lock to protect each version of the file system. This lock is managed to allow each filer access to the shared file system volume to create its new version. To share a fully-versioned file system, asynchronous updates at each of the filers is permitted, and each node is then allowed to “push” its individual changes to the store to form the next version of the file system. A mechanism also may be used to reduce the period during which filers in the group operate under lock.
摘要翻译：提供了多个实体之间数据共享的方法。每个实体向数据存储库导出包括该实体本地的版本化文件系统的结构化数据表示。该方法从形成包含两个或多个实体的共享组开始。启用共享组成员共享结构化数据表示。文件管理器使用单个分布式锁来保护文件系统的每个版本。管理此锁，以允许每个文件管理器访问共享文件系统卷以创建其新版本。要共享完全版本的文件系统，允许每个文件管理器的异步更新，然后允许每个节点将其各个更改“推送”到存储，以形成文件系统的下一个版本。也可以使用一种机制来减少组内的文件管理者在锁定期间的操作时间。
