Abstract
A system for distributed file storage includes a plurality of servers providing, to a plurality of clients, file access services for accessing files stored on the plurality of servers. A list of neighbor servers is maintained by each server. The neighbor servers are a subset of the plurality of servers. At least one server of the plurality of servers is switched into a neighbor group of servers based on network distance. Each file is stored in the form of a plurality of N pieces on N servers, the pieces being generated from the file. The list is used to obtain information for reconstructing files stored on the neighbor servers, such that any K out of the N pieces can be used to reconstruct any file.
