The Storage Performance Development Kit (SPDK) provides a set of tools and libraries for writing high performance, scalable, user-mode storage applications.
The SPDK project has a team of core maintainers who are responsible for providing technical oversight for the SPDK project, including final review and merging of patches into the SPDK code base. As the SPDK project continues to grow, the core maintainer team also needs to grow by adding contributors who are already demonstrating technical skill and leadership within the project. SPDK has seen increased interest in orchestration, especially the SPDK CSI Kubernetes plugin, so we are pleased to announce that Yibo Cai and Antti Kervinen are joining the core maintainer team with a specific focus on the spdk-csi project. Yibo and Antti will be responsible for helping define and refine the architecture and design for spdk-csi, as well as being primary reviewers for all incoming patches.

Although NVMe was still in its infancy, organizations integrating NVMe SSDs recognized the challenges they faced as the performance and efficiency of the storage software became increasingly critical to overall system performance. When Intel kicked off the SPDK Open-Source Community in 2015, a global phenomenon was born that was laser-focused on demonstrating the outstanding performance and efficiency enabled by running software designed for NVMe devices. In the beginning, the community demonstrated that it’s possible to build systems capable of millions of IOPS (I/O operations per second) using standard hardware. However, when solid-state media based on technologies like the Intel® Optane™ arrived, a whole new class of NVMe SSDs with higher throughput and an order of magnitude reduction in hardware latency the community saw an opportunity to redesign the SPDK NVMe driver. In 2019, a new SPDK NVMe driver capable of over 10 million IOPS (using a single CPU core!) was released and accompanied by a blog with deep technical insights on the techniques SPDK employs to achieved great performance. But the SPDK community is about both performance and scalability, so in 2021 we demonstrated a system that scaled to 80 million IOPS. We’re kicking off 2023 with another mind-blowing accomplishment.
