Emergency-management DPUs must support host-path networking offload for civic AI hosts. What unlocks those BlueField capabilities?
Select an answer to reveal the explanation.
Short Explanation
SR-IOV and PKey tricks won't unlock BlueField's host-path offload for you. Install NVIDIA DOCA instead, since that's what actually turns on the DPU networking capabilities those emergency-management hosts need.
Full Explanation
Emergency-management DPUs must support host-path networking offload for civic AI hosts; installing NVIDIA DOCA unlocks BlueField networking capabilities for those hosts. DOCA is what enables the DPU to take host-path networking work off the CPU so wildfire and emergency inference nodes can keep Spectrum-path performance without drowning the host in inline packet processing.
Spanning-tree enabled on data-plane VLANs carrying RoCE traffic fails by concept: STP is a loop-prevention/bridging mechanism inappropriate as a substitute for DPU offload software and can harm AI Ethernet designs by blocking the very paths RoCE needs. InfiniBand PKey partitioning logic transported via Spectrum BGP-EVPN overlays fails because PKeys are InfiniBand partition constructs; carrying that logic over an EVPN overlay does not unlock BlueField DOCA networking on Spectrum Ethernet. Enabling SR-IOV virtual functions on BlueField to share host-path connections for civic AI hosts fails: SR-IOV partitions NIC functions for virtual machines but does not install the DOCA stack or unlock the BlueField host-path networking offload required here.
Exam caveat: BlueField networking capabilities for civic AI hosts are unlocked by DOCA installation, not by STP on RoCE queues, IB PKey mapping onto EVPN, or enabling SR-IOV virtual functions to share host-path connections.
Operational check: install DOCA on emergency-management BlueField cards, confirm host-path networking offload features are available, enable per civic runbook, and validate CPU/offload counters under a representative emergency inference load on Spectrum.
