Скачать или смотреть SDC 2023 - Deep Dive & Comparison of NVMe RAID Solutions: Performance Analysis & Datapath Breakdown

In this presentation, I will delve into the world of NVMe RAID and present a comprehensive analysis and comparison of various NVMe RAID engines. Through comparative testing and performance analysis using state-of-the-art performance analysis tools, I have identified bottlenecks in these engines when handling different workloads. During the presentation, I will provide valuable insights and comparisons, showcasing significant figures that highlight the performance differences among the tested NVMe RAID solutions. Furthermore, I will conduct an in-depth examination of the datapaths employed by these engines, shedding light on their inner workings and architecture. Key focus areas of the presentation will include popular NVMe RAID engines such as mdraid, xiraid, RAID 5f from SPDK, and other notable products. By exploring their strengths and weaknesses, attendees will gain a comprehensive understanding of the capabilities and limitations of each solution. This presentation aims to provide the audience with practical knowledge and actionable insights, enabling them to make informed decisions when selecting the most suitable NVMe RAID solution for their specific requirements. The findings and comparisons shared will contribute to the ongoing advancement and optimization of NVMe RAID technology, driving improved performance and efficiency in storage systems.
