In this paper, the authors details a simulation intended to explore the viability of storage systems where data is placed intelligently depending on data-specific quality of service requirements and the characteristics of the underlying storage devices. Their implementation provides a framework for the automatic pro ling of a virtualized storage system, specification of data-level quality of service requirements, simulation of data streams acting on the storage system and visualization of the results. They demonstrate that an intelligent data placement algorithm can achieve a good match between desired and offered storage system quality of service.
