SPDK-Based User Space NVMe Over TCP Transport Solution

Explore the design, implementation, and development plan of TCP transport for NVMe over Fabrics (NVMe-oF) in SPDK in this 37-minute conference talk. Delve into the recently released NVM express specification for TCP transport (TP8000) and learn about SPDK's implementation on both host and target sides. Examine experimental results demonstrating the performance and scalability of SPDK's NVMe-oF TCP transport implementation. Discover techniques for further performance improvement, including leveraging user space TCP stack and hardware features like ADQ on Intel's E810 NIC. Gain insights into the target code design, TCP transport support, service efficiency, read command performance, latency, ongoing processes, interoperability, and the advantages of using SPDK for NVMe over TCP transport solutions.
