Summary:In order to implement huge data storage of high performance in embedded environment, more and more SSDs with Non-Volatile Memory Express (NVMe) standard are deployed and virtualized on heterogeneous multi-core platforms. Existing solutions of emulating NVMe SSD between guest operating system (OS) and remote OS rely on virtual machines (VMs), which bring in long I/O latency due to their expensive context switch and extra data transfer. In this paper, we propose NVMe over remote processor messaging (NVMe-over-RPMsg), a software framework that emulates remote storage system as local NVMe device, without requiring VMs. We implemented a prototype using ZCU102 FPGA board. The evaluation results show that NVMe-over-RPMsg has 45.4% reduction in latency and 1.74X improvement in throughput than native QEMU solution.
