Abstract
Design of storage system configuration is one of the key issues for providing dependable IT systems. An appropriate RAID storage configuration should consider both performance and availability. To assist the design, this paper presents the performability models for RAID10 and RAID6 that can be used to compare the configuration quantitatively. A performability advantage of RAID6 over RAID10 in sequential read access is discovered by the numerical study in conjunction with performance benchmark results.
