Abstract
Namespace service in a distributed file system using a database management system. A namespace database is configured on a namespace server with namespace identifiers and associated file location information. The namespace server is separate from the data servers in the distributed file system. A client proxy arrangement interfaces with client applications and with the namespace server to obtain from the namespace server location information associated with files referenced in file access requests and submit storage access requests to the appropriate data servers. The separate namespace server and data servers enhances scalability of the distributed file system.
