A city wants BlueField DPU-Arm services to accelerate east-west traffic for multi-node health models. What should ops deploy?
Select an answer to reveal the explanation.
Short Explanation
East-west health-model traffic belongs on the DPU path—deploy DOCA services on BlueField DPU-Arm. USB Wi-Fi and leaving the DPU idle will not offload that fabric. Turning off east-west traffic stops the multi-node models cold.
Full Explanation
To accelerate east-west traffic for multi-node health models, civic ops should deploy DOCA services on the BlueField DPU-Arm for networking offload. DOCA on the DPU provides the NVIDIA path to accelerate and manage AI fabric services without pretending USB Wi-Fi or host-only hacks are equivalents. That deployment matches municipal multi-node training networking needs where east-west chatter between ranks is a first-class performance path. Leaving BlueField unused while hoping the host CPU absorbs fabric work misses the DPU value proposition.
Replacing all BlueField DPUs with USB Wi-Fi adapters removes the DPU offload platform and cannot meet RDMA-class east-west requirements for health-model training. Running DOCA only on the host CPU and leaving DPU-Arm unused wastes BlueField capability and misses the DPU service model. Disabling east-west traffic so health models cannot communicate breaks multi-node training outright and is not an acceleration strategy.
Exam caveat: east-west acceleration for civic multi-node AI maps to DOCA on BlueField DPU-Arm—not host-only DOCA theater or consumer Wi-Fi substitutions. Operational check: deploy DOCA networking services on the BlueField DPU-Arm, verify service health in BCM/DPU views, run a multi-node health-model job, and confirm east-west offload/telemetry reflects DPU-side services rather than disabled fabric.
