NVMe over fabrics (NVMe-oF) extends NVMe protocol from PCIe to fabrics and aims at providing high performance on accessing remote NVMe devices. In this talk, an accelerated NVMe-oF target is introduced with SPDK (storage performance development kit) technique. SPDK provides a set of tools and libraries for writing high performance, scalable, user-mode storage applications. It achieves high performance by moving all of the necessary drivers into user space and operating in a polled mode (similar with the idea in DPDK) instead of relying on interrupts, which avoids kernel context switches and eliminates interrupt handling overhead. The accelerated NVMe-oF target relies on SPDK’s framework, user space NVMe driver, environment library encapsulated from DPDK’s EAL library (e.g., thread and memory management) and standard fabrics library (e.g., ibverbs) to provide high performance block service. Compared with Linux kernel’s NVMe-oF target, our solution can is much more efficient with 10X improvement in per CPU core aspect.
