Abstract： As a key component for offloading and accelerating key services in cloud data centers, smart NIC is significant for improving the processing efficiency of network and storage services in data centers. The service needs of data centers are complicated, lacking the support of mature commercial chips, and the design of smart NIC is difficult to meet the multiple requirements of service offloading flexibility, high performance, cost economy and so on in a limited space. Designing a separate architecture scheme to physically decouple the smart NIC interface function from the service offload processing function, break through the physical space limit of the network card, reuse the service offload processing hardware resources, and improve the cost economy is an effective way to achieve the engineering and large-scale deployment of smart NIC.
Key words : smart NIC；virtio；elastic bare metal server；block offloading engine
