一种智能网卡新型架构研究与设计

Research and design of smart NIC’s new architecture

作为云数据中心核心业务卸载及加速处理的关键部件,智能网卡对于数据中心网络、存储业务处理效率提升具有特殊意义。数据中心业务需求复杂多变,缺乏成熟商用芯片支持,智能网卡设计难以在受限空间内满足业务卸载灵活性、高性能、成本经济性等多重要求。设计一种分离架构方案,将智能网卡通信接口功能与业务卸载处理功能进行物理解耦,突破网卡物理空间限制,复用业务卸载处理硬件资源,改善成本经济性,是实现智能网卡工程化和大规模部署的有效途径。

As a key component for offloading and accelerating key services in cloud data centers,smart NIC is significant for im‐proving the processing efficiency of network and storage services in data centers.The service needs of data centers are compli‐cated,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.
