Performance Tuning Storage Systems Using DOEs

Member Submitted

This paper discusses the suitability of the design of experiments (DOE) methodology for storage performance tuning. The DOE estimates the main and interaction effects of three major storage factors viz, cache partition size (CPS), LUN strip size (LSS), and cache segment size (CSS) settings of an enterprise level storage system on the overall storage performance. Other factors influencing performance are kept constant throughout the experiment to minimize experiment duration and complexity. DOE has provided key ideas for effectively analyzing the relationship of storage factors in storage performance tuning.
