1. The NIC SR-IOV is used. Each OSD uses an exclusive VF NIC. 2. The DPDK interrupt mode is added. 3. The single-CPU core and multiple NIC queues are implemented to improve performance. 4. The admin socket command is added to obtain the NIC status, collect statistics, and locate faults. 5. Adjust the CEPH throttling parameters, TCP, and DPDK packet sending and receiving buffer sizes to prevent packet loss and retransmission. 6. The Crimson message component uses the Seastar DPDK.
