A device, system, and method are directed towards enabling a user to disambiguate an identity of a member included in a user's social network (USN), and towards enabling an operation to be performed based on information about the member. The USN is determined. The namespace identifier (NID) of the member is received. If the NID is non-unique within the USN, member distinctions are determined for members in the USN who are associated with the same NID. The member distinctions are sent to the user. The user makes a selection of one of the members associated with one of the member distinctions. Based on the selection, information about the selected member is received. The operation is enabled to be performed based on the information about the selected member. The operation may include addressing the selected member, enabling a communication between the user and the selected member, or the like.

A plurality of network file manager switches interoperate to provide remote file virtualization. Copies of file data and / or metadata are maintained at a central site and at one or more remote sites. The network file manager switch at the remote site may satisfy certain client requests locally without having to contact the network file manager switch at the central site. A global namespace is maintained and is communicated to all network file manager switches.

A global namespace (GNS) is constructed across heterogeneous network-attached storage (NAS) devices by organizing metadata servers into a cluster layer having cluster nodes and a consistent hashing overlay layer having overlay nodes. The global namespace is distributed based on workload at the cluster and overlay nodes, and a portion of the GNS namespace may be migrated from one layer to the other. Cluster nodes may be added to the cluster layer, overlay nodes may be added to the consistent hashing overlay layer. Further, a cluster node may become an overlay node or an overlay node may become a cluster node. To access the global namespace, a request for namespace metadata managed by a cluster node is serviced by the cluster node, but if the requested namespace metadata have been migrated to the consistent hashing overlay layer, the cluster node will forward the request to the responsible overlay node for servicing.

A method and apparatus for managing network attached storage that includes detecting frequency of access from a client to a data item that is in a first server in the network attached storage, a global namespace of the network attached storage indicating an access address for accessing the data item, the access address including a first address of the data item in the first server; in response to the frequency being higher than a predetermined threshold, copying the data item from the first server to a second server in the network attached storage which is proximate to the client, so as to form a data image; and updating the global namespace so as to add to the access address a second address of the data image in the second server whereby the data access efficiency of the network attached storage can be considerably improved.

Embodiments relate to forwarding of packets in link aggregation environments. A method for forwarding a packet through an extended switch including a first port extender and a second port extender directly or indirectly communicatively coupled to respectively a first interface and a second interface of a controlling bridge includes, associating a first port extender interface of the first port extender with a global namespace or an interface-specific namespace. The method further includes receiving a packet through the first port extender interface, marking the received packet with an indication of the namespace configuration of the first port extender interface, processing the marked packet in the controlling bridge based at least in part upon the indication, and transmitting the processed packet out of the controlling bridge.

The disclosed embodiments disclose techniques for maintaining global name consistency for a distributed filesystem. Two or more cloud controllers collectively manage distributed filesystem data that is stored in one or more cloud storage systems; the cloud controllers ensure data consistency for the stored data, and each cloud controller caches portions of the distributed filesystem. During operation, a cloud controller receives a client request to perform a namespace operation upon a filesystem object. The cloud controller contacts the cloud controller that manages (“owns”) the portion of the global namespace for the distributed filesystem that includes the filesystem object. This second cloud controller ensures the consistency of the filesystem object across the distributed filesystem during the namespace operation.

The invention provides an intelligent data service method based on a distributed system. A master node of the distributed system is used for managing global file namespace; and in processes of writing files into the distributed system and reading files from the distributed system, the master node of the distributed system is used for analyzing and processing requests of clients, selecting specific data preprocessing programs, distributing the programs to slave nodes of the distributed system for subsequent data preprocessing and transmission. According to the intelligent data service method based on the distributed system, prior distributed system storage space can be clustered rapidly in data intensive application environments; computing resources of the distributed system are fully used, so that data services can be provided intelligently according to requests of external computing devices; and part of data processing loads are further transferred from external computing devices to the distributed system, and accordingly, bandwidth requirements for providing data services for external computing devices are reduced.
