Abstract:
A clustered server network for receiving, storing and retrieving usenet articles. The clustered server network includes various sets of clustered servers. One set of clustered servers receives articles from peer usenet networks, while another set of clustered servers stores only header information for each unique article. A third set of clustered servers may be dedicated to storing, in a redundant fashion, each unique article. The articles are stored based on a deterministic calculation so that each unique article stored is found in at least one particular server(s). The redundant storage of each unique article eliminates a need for a backend server cluster for storing one copy of every article. A usenet system provides for continuous operation even if any server in any cluster becomes non-operational. A server rebuild function is provided in the usenet system.
