Abstract:

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.

709227, 709203, 709225

Abstract:

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.

International Classification:

G06F 17/30

US Classification:

707010000

Abstract:

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.

International Classification:

G06F 21/00

US Classification:

726 12, 709227

Abstract:

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.
