In this article, we present FastPath_MP, a novel low-overhead and energy-efficient storage multi-path architecture that leverages FPGAs to operate transparently to the main processor and improve the performance and energy efficiency of accessing storage devices. We prototyped FastPath_MP on both Arm-FPGA Zynq 7000 SoC and Zynq UltraScale+ MPSoC and evaluated its performance against standard microbenchmarks as well as the real-world in-memory Redis database. Our results show that FastPath_MP achieves up to 82% lower latency, up to 12× higher throughput, and up to 10× more energy efficiency against the baseline storage path of the Linux kernel.

快速路径_MP

在本文中，我们介绍了 FastPath_MP，这是一种新颖的低开销和高能效存储多路径架构，它利用 FPGA 对主处理器透明地运行，并提高访问存储设备的性能和能源效率。我们在 Arm-FPGA Zynq 7000 SoC 和 Zynq UltraScale+ MPSoC 上对 FastPath_MP 进行了原型设计，并根据标准微基准测试以及真实的内存中 Redis 数据库评估了其性能。我们的结果表明，与 Linux 内核的基线存储路径相比，FastPath_MP 的延迟降低了 82%，吞吐量提高了 12 倍，能源效率提高了 10 倍。
