Paper Title: Enabling Realistic Simulations of the Latest Multi-Queue SSDs

Paper Abstract: As the I/O demands of SSD-based storage systems keep increasing, manufacturers are striving to meet them. For example, new high-bandwidth interfaces. such as PCIe/NVMe, have replaced the conventional SATA host–interface protocol. However, existing simulation tools do not capture the new features. A new simulator MQSim models them accurately. It faithfully captures new high-bandwidth protocol implementations, steady-state SSD conditions, and the full end-to-end latency of requests in current SSDs. Results show that by modeling critical features of the latest SSDs, MQSim has led to the uncovering of important issues not captured by existing simulators.
