Zusammenfassung:It is very important to recover data immediately at a single disk failure for critical applications such as multimedia storage systems, real-time systems and so on. As an efficient solution, the paper proposes a hybrid scheme to improve the performance before a failed disk is replaced with a new disk and it does not require an additional disk to recover data. The hybrid scheme is evaluated and its performance is analyzed for various request sizes using the simulation. The results show that the performance of the hybrid scheme is improved by up to 85% compared with that of RAID level 5 in the reconfigured mode.
