Storage system is set up by using the basic capability of a storage device, such as adding layers of hardware and software to obtain a highly reliable, higher performance, and easily managed system. We present the design, implementation, and evaluation of the HRDCC (HUST-RAID Dual Controller based on Controller). To address the problem of single point of failure with a single RAID controller, HRDCC was devised to avoid data loss or even data corruption. Evaluations of the storage system dependability have focused mainly on disk arrays, including the dependability of array hardware and RAID mec...
