Reliability and performance of RAIDs
1995
IEEE transactions on magnetics
We define and analyze the ACATS declustering scheme for use with the classic Level 5 as well as MDS RAIDs. ACATS provides a paradigm for distributed sparing and checking as well. Using Markov models we calculate the reliability of classic Level 5 as well as MDS RAIDs both with and without ACATS. Our results demonstrate, for fixed hardware configurations, tradeoffs between performance and reliability within these RAID organizations. Our analysis assumes a transaction oriented environment.
