Aiming at the disadvantage of high availability based on node redundant, a high availability scheme based on storage devices redundant was researched and designed in large-scale cluster system with network storage devices by working on system kernel. The advantages of low-cost, low-complexity of maintenance and high-utilization of resources were received. Besides, an asynchronous prototype system of high availability based on log was implemented. Test proved that anticipated goals in system performance, data consistency and availability were achieved.
