Abstract:

A distributed heterogeneous or homogeneous file storage system divides logical responsibility for data from actual control of the data by using separate file and storage managers. Each file manager provides access to stored files and stores metadata associated with each of the files for which it is responsible. A file manager control component allocates responsibilities among file managers, assigns management responsibilities for individual files, and maintains a record of which files are assigned to each manager. Each storage manager is responsible for managing storage of files on data storage devices and maintains a record of the location of each stored file. A storage manager control component allocates responsibilities among storage managers, assigns responsibilities for individual files, and maintains a record of which files and storage devices are assigned to each manager. A client provides user access, initiates actions within the system, and implements a redundant data recovery and reconstruction scheme.
