Showing Results for DPUs & SmartNICs

DPUs (Data Processing Units) and SmartNICs are programmable network adapters that offload packet processing, security, storage virtualization, and telemetry tasks from host CPUs to dedicated on-card processors. This category includes PCIe adapters from vendors such as NVIDIA BlueField, Intel IPU (Infrastructure Processing Unit), Marvell OCTEON, and Pensando/AMD DSC series, spanning 25 GbE through 400 GbE line rates, with form factors ranging from standard PCIe cards to OCP 3.0 mezzanine modules. Key buying considerations include host interface bandwidth (PCIe 4.0 vs. 5.0), on-card ARM core count and memory capacity, supported offload engines (RDMA/RoCEv2, NVMe-oF, IPsec/TLS, OVS), and SDK/programming model compatibility with your orchestration stack.

Primary use cases include hypervisor bypass and micro-segmentation enforcement in cloud and private datacenter deployments, NVMe-oF storage target acceleration, GPU-to-GPU RDMA fabric management in AI training clusters, and zero-trust network security enforcement without host CPU overhead. Infrastructure teams building disaggregated storage architectures, network engineers implementing eBPF-based observability at line rate, and AI operators managing high-density GPU nodes all rely on DPUs and SmartNICs to free host compute resources for workloads rather than infrastructure overhead.
