4. Goal An efficient, accurate, flexible, and highly-configurable storage system simulator for some interesting research topics. Simulate behaviors of storage devices to understand storage performance and evaluate new architecture. Support three kinds of storage devices, including RamDisk, flash memory, hard disk Support multi-configuration, i.e. disk caching, scalability, etc.

5. Schedule November Choose programming language, probably SystemC. Design interface of whole storage system and configuration settings of black boxes(three kinds of storage devices) for basic and advanced functions. Check specifications of RamDisk, FlashMemory, and HardDisk for settings of our simulation tools. Spec input(configurations) and output(performance numbers). Think about case studies. Trace may be a problem. December (~January) Implementation and construct a preliminary model. Revise and test and verify the correctness of our work.

6. RF2 - Simulation model Model language : systemc Provide an environment to enable synchronous timing model in multi-tasks Composed of system process, disk hardware and requests from clients Treat all component as a black box for simplicity
