ABSTRACT:
Method and system for distributing prefragmented data processing loads in a fault tolerant system linked in a ring topology of disk subsystems and data processing nodes. The data processing load of the node under fault is shifted in one direction along the ring, and adjacent nodes in the same direction along the ring successively shift their entire data processing loads to their immediately adjacent data processing nodes. The adjacent data processing nodes in the non-shifted direction absorb increased workloads by one net data fragment each until the entire data processing load of the data processing node under fault is absorbed.
