The text discusses how SmartNICs, which offload tasks from CPUs, have been replaced by DPUs and IPUs, which offer more control and acceleration at the processing level. The text mentions Intel's BlueField-3 DPU and Marvell's OCTEON 10 DPU as examples of these technologies. DPUs and IPUs differ from SmartNICs in that they have control planes and can be self-managed, allowing for more efficient and secure large-scale computing applications. The text also mentions Facebook's report on the benefits of IPUs in microservices architecture and the advantages of using IPUs instead of CPUs for infrastructure processing.本文介绍了数据处理技术的演变，从 SmartNIC 到 DPU 和 IPU，重点介绍分布式计算和连接分布式计算能力的高速网络需求。本文讨论了从 CPU 卸载任务的 SmartNIC 如何被 DPU 和 IPU 所取代，后者在处理级别提供更多控制和加速。文中提到了 Intel 的 BlueField-3 DPU 和 Marvell 的 OCTEON 10 DPU 作为这些技术的示例。DPU 和 IPU 与 SmartNIC 的不同之处在于，它们具有控制平面，并且可以自我管理，从而实现更高效、更安全的大规模计算应用程序。该文本还提到了 Facebook 关于 IPU 在微服务架构中的优势以及使用 IPU 而不是 CPU 进行基础设施处理的优势的报告。 | |

While NICs are built around ASICs designed as ethernet controllers, SmartNICs are defined as network cards that allow software to be loaded onto the NIC after purchase to add new features or support other functions. The main difference between a regular NIC and a SmartNIC is that the latter offloads processing from the host CPU and is designed around FPGA platforms. SmartNICs require additional computational power and onboard memory, which regular NICs lack. The article compares the SmartNIC offerings of six companies: Broadcom (Brocade), Intel, Nvidia (Mellanox), Xilinx (Xilinx), Netronome, and Pensando. Broadcom's Stingray SmartNIC uses a single chip method, while Intel's N3000 SmartNIC uses multiple chips. Xilinx's Alveo U25 uses a Zynq SoC, which includes an FPGA and an Arm CPU. Pensando's DSC-25 uses a Capri processor with parallel P4 processing units. The article also discusses the potential benefits of SmartNICs, such as offloading network processing tasks from the host CPU and extending computing power to the network edge.本文讨论了传统网络接口卡 （NIC） 和 SmartNIC 之间的区别。NIC 是围绕设计为以太网控制器的 ASIC 构建的，而 SmartNIC 则被定义为允许在购买后将软件加载到 NIC 上以添加新功能或支持其他功能的网卡。常规 NIC 和 SmartNIC 之间的主要区别在于，后者从主机 CPU 卸载处理，并且是围绕 FPGA 平台设计的。SmartNIC 需要额外的计算能力和板载内存，而普通 NIC 则缺乏这些。本文比较了六家公司的 SmartNIC 产品：Broadcom （Brocade）、Intel、Nvidia （Mellanox）、Xilinx （Xilinx）、Netronome 和 Pensando。Broadcom 的 Stingray SmartNIC 使用单芯片方法，而 Intel 的 N3000 SmartNIC 使用多芯片。Xilinx 的 Alveo U25 使用 Zynq SoC，其中包括一个 FPGA 和一个 Arm CPU。Pensand 的 DSC-25 使用带有并行 P4 处理单元的 Capri 处理器。本文还讨论了 SmartNIC 的潜在优势，例如从主机 CPU 卸载网络处理任务，并将计算能力扩展到网络边缘。 | |
