公众号记得加星标⭐️，第一时间看推送不会错过。 数据中心通常被认为是 CPU（x86、ARM、RISC-V）和 GPU（NVIDIA、AMD、定制 ASIC）之 间的较量。但在这些备受瞩目的竞争背后，另一场静悄悄的革命正在上演：ARM 悄然取代了英特尔 和 AMD 在数据处理单元 (DPU) 市场的份额。 DPU（也称为 SmartNIC）负责数据中心的"管道"。它们通过管理数据包处理、TCP/IP 和 RDMA 来 减轻网络负载。它们处理压缩、加密和 NVMe-over-Fabrics (NVMe-oF) 等存储服务。它们强制执行 安全隔离，这在多租户云环境中至关重要，因为信任边界会不断受到考验。此外，它们还负责执行编 排任务，否则这些任务会浪费宝贵的 CPU 周期。 NVIDIA （ 通 过 Mellanox 开 发 的 BlueField ） 、 Marvell （ OCTEON ） 、 AMD （ Pensando ） 和 Broadcom 均在其 DPU 中采用了 ARM 内核。原因很简单：ARM 内核体积小、功耗低、可授权， 并且已经嵌入到网络芯片中。当英特尔推出其基础设施处理单元 (IPU) 计 ...
