In an array storage system based on EVENODD, the traditional single disk failure recovery requires reading all the remaining data. Even if the hybrid recovery method is used, the theoretical limit of the data reading cost can be reduced by only 25%.To further reduce the read overhead for single disk failure recovery, improve the reliability of storage system, this paper proposes an improved method for EVENODD single disk failure recovery. This method is to reduce the amount of data that needed to read during recovery by adding a local redundant. The experimental results show that the improved method has significantly improved the recovery time comparing with the EVENODD.
