摘要： Techniques are described for a proxy system to provide a client device with transparent access to multiple network file servers. The proxy system may appear to the client device as a single network file server. The proxy may be configured to forward requests received from the client device to multiple servers as well as provide responses from the server back to the client. Further, the proxy system may authenticate itself, as the client, to each of the multiple network servers using authentication credentials supplied by the client. After prompting a user to submit credentials to establish a session with a first network server, the proxy system may send a session timeout error code, prompting the client to submit a fresh authentication request used by the proxy system to establish a session with a second network server.

摘要： A system and method for performing policy-based storage management using data related to access frequency and file attribute accumulation. A switch device provides transparency for transactions between a client and a storage network. The transparency allows objects (e.g., files or directories) to be moved (e.g., migrated) on the storage network without affecting a reference to the object used by the client (e.g., a file handle). A monitoring module generates accumulation data associated with the transactions for use in policy-based management. The accumulation data can describe uses of the file such as how often certain files are accessed, modifications to files such as creations of new directories or files, and other uses.

摘要： A NAS switch provides mirroring in a NAS storage network that is transparent to client. A source file server exports an original NAS file handles indicative of object locations on the source file server to the NAS switch. The NAS switch modifies the original NAS file handles to an internal file system and maps the original NAS file handles to a switch file handles independent of location. The NAS switch exports the switch file handles to a client. The client looks-up objects and makes NAS requests to the source file server using switch file handles. The NAS switch performs mirroring of a namespace when during processes such as data migration, data replication, and data snapshot.

摘要： A NAS (Network Attaches Storage) switch authenticates a client on multiple file servers for proxy services. The NAS switch enables proxy services by successively authenticating the client on the file servers using referrals. The NAS switch further comprises a connection manager to establish connections to the client and the file servers, a referral manager to redirect the client for successive authentications, and a transaction manager to perform data transfers with the file servers on behalf of the client. The system components support DFS (Distributed File System), and communicate using a protocol dialect that supports referral mechanisms such as NFSv4 (Network File Server version 4) or CIFS (Common Internet File System). The transaction manager also performs a protocol dialect translation service when the connection manager negotiates one protocol dialect with the client, and a different protocol dialect with the file server.

摘要： The present invention provides selective migration in a storage network in accordance with a policy. The policy can include rules that establish which objects are migrated from a source file server to a destination file server based on file attributes (e.g., file type, file size, last access time, frequency of access). For example, large multimedia files that consume I/O bandwidth on expensive or critical file servers, without adding much value to enterprise productivity, can be migrated to a commodity or less critical file server.
摘要翻译： 本发明根据策略提供了在存储网络中的选择性迁移。 该策略可以包括基于文件属性（例如，文件类型，文件大小，最后访问时间，访问频率）确定哪些对象从源文件服务器迁移到目的地文件服务器的规则。 例如，在昂贵的或关键的文件服务器上消耗I / O带宽的大型多媒体文件，而不增加企业生产力的价值，可以迁移到商品或不太关键的文件服务器。
