摘要： An intelligent network client has the capability of accessing a first network server in accordance with a first high-level file access protocol, and responding to a redirection reply from the first network server by accessing a second network server in accordance with a second high-level file access protocol. For example, the intelligent network client can be redirected from a CIFS/DFS server to a NFS server, and from an NFSv4 server to a CIFS server. Once redirected, the intelligent network client performs a directory mounting operation so that a subsequent client access to the same directory goes directly to the second network server. For example, the first network server is a namespace server for translating pathnames in a client-server network namespace into pathnames in a NAS network namespace, and the second network server is a file server in the NAS network namespace.

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 NAS network namespace. The namespace server also translates between different file access protocols. If a client supports redirection and is requesting access to a file in a file server that supports the client's redirection, then the namespace server may redirect the client to the NAS network pathname of the file. Otherwise, the namespace server forwards a translated client request to the file server, and returns a reply from the file server to the client. A file server may redirect a redirection-capable client's access back to the namespace server for access to a share, directory, or file that is offline for migration, or for a deletion or name change that would require a change in translation information in the namespace server.
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机请求转换为对NAS网络命名空间中路径名引用的文件的访问请求。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。如果客户端支持重定向并请求访问支持客户端重定向的文件服务器中的文件，则命名空间服务器可能将客户端重定向到该文件的NAS网络路径名。否则，命名空间服务器将转换的客户端请求转发到文件服务器，并将文件服务器的答复返回给客户端。文件服务器可能将重定向重定向客户端的访问重定向到命名空间服务器，以访问脱机的共享，目录或文件进行迁移，或者需要在命名空间中更改翻译信息的删除或名称更改服务器。

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： A hierarchical storage system is constructed from file servers and a policy engine server by building upon a file migration service. Offline attributes are added to file system inodes in a primary file server, file system parameters are added in the primary server, an offline read access method field is added to a connection database, and the primary file server is programmed to use these attributes and parameters for selecting a particular method (such as a partial read migration or a pass through read method) for read access to an offline file. In this fashion, the primary file server is provided with flexibility for selecting a particular one of a number of migration methods depending on various conditions, in order to improve the trade-off between the cost of storage and delay in file access.

摘要： A read-write snapshot copy facility is constructed from a hierarchical storage management facility. The read-write snapshot copy file system initially comprises stub files pointing to the files in a read-only snapshot copy file system. When an application writes to a file in the read-write snapshot copy, the read-write snapshot copy facility migrates a copy of the file to replace the stub file, and then writes to the migrated file. Because the read-write snapshot copy facility references the files in the read-only snapshot file system in a network namespace using standard protocols such as NFS or CIFS, the read-write snapshot copy facility permits referencing of distributed read-only snapshot file systems in an open (heterogeneous) network environment, and the read-write snapshot copy is scalable by linking the read-write snapshot copy facility to multiple file servers containing read-only snapshot file systems.
