SPDK Based User Space NVMe Over TCP Transport Solution
summary
SPDK implements both host and target NVMe-over-TCP transports, interoperates with the Linux kernel, and shows concrete benchmarks: 4K random 70/30 R/W workloads with up to ~16 initiator connections, delivering roughly 2–2.5× better throughput for the same CPU and about 20–30% lower latency versus kernel targets. Implementation uses a polled user-space threading model and a socket wrapper; future work includes user-space TCP (VPP+DPDK) integration and ADQ on Intel E810 NICs to further cut latency and offload CPU.
