Using a queuing model of disk arrays, we study the performance and tradeoffs in disk array subsystems and develop guidelines for designing these sub-systems in various CPU environments. Finally, we compare our model with some earlier simulation results. Key Words and Phrases: Disk array, Striped disk, Synchronized disk i Copyright c fl 1990 by Mikito Ogata and Michael J.
