摘要: In an embodiment, a method to provide data consistency in a storage system, includes: providing, by a server to a proxy cache, a lock associated with a delegated file in the server; in response to a write request from a client, modifying data in a cached copy of the delegated file in the proxy cache; revoking, by the server, the lock associated with the delegated file, in response to a request from another device to access the delegated file so that the delegated file is now a formerly delegated file; and writing the modified data to the formerly delegated file in the server to update the formerly delegated file; and permitting access to the formerly delegated file by the another device.

摘要: The invention includes a method for selecting a replicated node from a domain of replicated nodes in a computer network. The method comprises maintaining a list of the replicated nodes; receiving a name resolution request to resolve a name for the domain into a network address; selecting one of the replicated nodes based on predefined selection criteria and in response to the name resolution request; and sending a network address of the selected replicated node to a network address associated with the name resolution request.
