"WebSPDK provides both a user space NVMe-oF target and initiator that extends the software efficiencies of the rest of the SPDK stack over the network. The SPDK NVMe-oF target uses the SPDK user-space, polled-mode NVMe driver to submit and complete I/O requests to NVMe devices which reduces the software processing overhead.
