Reliability analysis of redundant arrays of inexpensive disks


Journal Article

A reliability analysis of various disk array architectures (different levels of RAID) is performed. The dependence of reliability and mean time to data loss on various parameters of a disk array is characterized. A study of these characteristics reveals the impact of several design choices for a disk array on its reliability. Issues such as scalability of disk arrays, imperfect coverage of disk failures, cold versus hot spares, effect of predictive disk failures, and dependence of disk array reliability on data reconstruction time are studied. © 1993 Academic Press, Inc.
