<p>A server system (2) for storing and supplying data to a destination includes a plurality of disk drives (4) for storing data, a buffer memory (8) for temporarily storing a portion of the data from the disk drives (4), a reconstruction unit (10) for reconstructing a portion of the data from at least one of the disk drives (4) using a portion of the data from a plurality of the remaining disk drives (4) so that at least one of the disk drives (4) holding data belonging to the current parity group can be bypassed (either because that disk (4) is faulty or because there are already many queued read-requests for it), a control unit (12) for controlling the server system (2), and an output unit (14) for outputting data from either or both of the buffer memory (8) and the reconstruction unit (10). The server system (2) reduces congestion problems, reduces buffering requirements, and provides load balancing and fault tolerance. The server system may be a video storage server. <IMAGE></p> |
