  • Title : Cutting-down SSD Infrastructure for Full System Simulation
  • Speaker : Prof. Myoungsoo Jung


There are significant technology shifts in modern flash-based solid state disks (SSDs), and therefore, performance estimations by taking into account a variety of design parameters become more non-trivial. Unfortunately, detailed SSD models often exhibit unreasonably long simulation run-times and requires too much resources to estimate overall performance with diverse configurations. In this talk, we will introduce a high-fidelity simulation framework, which not only can reconfigure hardware parameters such as flash types, channel frequencies, and different interconnections, but also reconstruct software modules, including address translation, garbage collection and wear-levelling. In contrast to the existing simulators, this brand-new simulator can capture a wide spectrum of storage-internal performance as well as overall system performance by executing diverse CPU benchmarks.
