FAQ
Ask a QuestionFind answers to common questions about our products.
What does “externally managed” mean for the MQM9790?
MQM9790 does not provide the local network operating environment typically available on a managed switch. Fabric initialization, routing, device discovery, and ongoing administration are handled by an external host running OpenSM or NVIDIA UFM.
Why can the fabric remain unavailable even after all switches, adapters, and cables are connected?
An InfiniBand fabric requires a running Subnet Manager to discover devices, assign LIDs, and establish routing. Physical connectivity alone does not create an operational fabric. Verify that OpenSM or UFM is running properly on a server connected to the InfiniBand network.
Is OpenSM sufficient, or should I deploy NVIDIA UFM?
OpenSM is often sufficient for smaller fabrics with a simple topology and limited operational requirements. NVIDIA UFM is better suited to multi-switch environments, larger GPU clusters, and deployments that require centralized monitoring, alerting, performance visibility, and faster fault isolation.
