ABSTRACT:
Embodiments of the invention provide methods and apparatus for improving the performance of file transfer to a client from a distributed storage system which provides single name space to clients. In one embodiment, a system for providing access to files in a distributed storage system comprises a plurality of storage nodes and at least one computer device connected via a network. Each storage node is configured, upon receiving a file access request for a file from one of the at least one computer device as a receiver storage node, to determine whether or not to inform the computer device making the file access request to redirect the file access request to an owner storage node of the file according to a preset policy. The preset policy defines conditions for whether to redirect the file access request based on at least one of file type or file size of the file.
