From DPU to Fabric: Multi-Tenant Network Automation with NVIDIA NICo and Aviz ONES
Multi-tenant AI infrastructure spans two networking domains. The first is the GPU host and DPU layer, where tenant networking begins. The second is the data center fabric, where that tenant needs to reach storage, shared services, and external networks. Both domains must work from the same tenant information. NVIDIA Infra Controller (NICo) and Aviz ONES handle this by splitting the work clearly. NICo manages GPU hosts and their BlueField-3 DPUs and sets the network identity for each tenant. ONES takes that identity and extends it across the AI fabric. NICo: The Source of Truth for Tenant Identity NICo works closest to the workload. When a GPU server is assigned to a tenant, NICo configures its BlueField-3 DPU with the details needed to identify and isolate that tenant: VLAN VNI VTEP information Since these values are created during host provisioning, NICo holds the authoritative tenant network identity. The fabric does not assign its own identifiers. It uses the ones NICo already a...
