ABSTRACT:
A sewer system for storing and supplying data to a destination. The server system includes a plurality of disk drives for storing data, a buffer memory for temporarily storing a portion of the data from the disk drives which is soon to be supplied, a reconstruction unit for reconstructing a portion of the data from at least one of the disk drives using a portion of the data from a plurality of the remaining disk drives so that at least one of the disk drives holding data belonging to the current parity group can be bypassed (either because that disk is faulty or because there are already many queued read-requests for it), a control unit for controlling the server system, and an output unit for outputting data from either or both of the buffer memory and the reconstruction unit. The server system prevents congestion problems from persisting, reduces buffering requirements, and provides load balancing and fault tolerance. Preferably, the server system is a video storage server and the data being stored is video data. Methods of storing data to and retrieving data streams from the disk drives are also disclosed.
