To fully understand the impact of SSD design and microarchitecture on end-to-end application performance, researchers must delve deeper than treating SSDs as black-box components. Unfortunately, acquiring multiple SSDs for research is costly and inefficient, as the underlying microarchitecture remains hidden from the system designer. Although simulators have become the preferred method for studying SSDs, existing software-based simulators are limited in terms of real data transfers and cannot simulate the overhead associated with NVMe and PCIe interfaces. Additionally, simulating an entire SSD using software is a time-consuming process, constraining the number of experiments that can be conducted within a reasonable timeframe. To address these challenges, we introduce FSSD, an FPGA-based emulation system that accurately models NAND flash access patterns, the latency, and the energy consumption of a real NVMe SSD. FSSD capitalizes on the flexibility of an FPGA, enabling users to customize SSD microarchitecture features and explore the design space for data-intensive applications. Based on FSSD, we further introduce FSSD-EM with a built-in Garbage Collection (GC) algorithm and energy modeling module. In contrast to most software simulators that rely on Virtual Machines (VM), FSSD-EM is capable of interacting with real Operating Systems (OS).
