NVIDIA NCP-AIO - NVIDIA AI Operations

Comprehensive and Detailed Explanation From Exact Extract:

TheUFM Telemetryplatform provides basic network monitoring and validation capabilities, making it suitable for organizations that require foundational insight into their network status without advanced analytics or AI-driven cybersecurity features. Other platforms such as UFM Enterprise or UFM Pro offer broader or more advanced functionalities, while UFM Cyber-AI focuses on AI-driven cybersecurity.

Generatingdebugging logsenables detailed visibility into the internal operations of the Docker daemon. These logs expose low-level errors, misconfigurations, and runtime issues that standard logs might not capture, making them essential for diagnosing why a container repeatedly fails to start.

For troubleshooting and performance optimization on NVIDIA DGX systems such as DGX H100, theNVIDIA System Management (nvsm)tool is used to gather system health and diagnostic data. The command nvsm dump health is the correct command to generate and export detailed system logs related to the health report of the DGX system.

nvsm show logs --save is not a recognized command format.

nvsm get logs retrieves logs but does not specifically dump the health report logs.

nvsm health --dump-log is not a standard documented nvsm command.

Therefore, nvsm dump health is the valid and documented command used to generate system logs focused on health reporting, useful for diagnosing performance issues in DGX H100 systems.

This usage aligns with NVIDIA’s system management tools guidance for DGX platforms as described in NVIDIA AI Operations documentation for troubleshooting and performance optimization.

Communication issues between UFM server and InfiniBand switches often result from misconfigured or missingsubnet manager configurationon the switches. The subnet manager controls fabric membership and routing, so verifying and correcting its setup is essential for proper UFM operation. Rebooting, adding GPUs, or disabling firewalls are less likely to resolve fabric-level communication problems.

To verify the optimal communication path and diagnose issues between two nodes in an InfiniBand fabric, theibtracertcommand is used. It traces the route that InfiniBand packets take through the fabric, identifying each hop and any potential bottlenecks or faulty links along the path.

ibstatusprovides status information about local InfiniBand devices and ports.

ibpingtests connectivity and latency between nodes.

ibnetdiscoverdiscovers and prints the topology of the InfiniBand fabric but does not trace specific paths.

Therefore,ibtracertis the appropriate tool for path optimization verification between two compute nodes.

In NVIDIA Base Command Manager (BCM), assigning theprovisioning roleto a node enables that node to manage software images and perform provisioning tasks for other nodes in the cluster. This role allows automated deployment and configuration of cluster nodes, ensuring consistency and simplifying large-scale management. It is not primarily responsible for container orchestration, GPU monitoring, or storage management.

NVIDIA Fabric Manager is designed to manage and optimize fabric resources like NVLink and NVSwitch inenterprise-class platforms such as HGX and DGX systems. These platforms have the necessary hardware fabric components. The L40S Certified and GeForce series are either not compatible or do not require Fabric Manager.

The Base Command Manager command shell (cmsh) accepts the-cflag to execute multiple commands sequentially. Usingcmsh -c “main showprofile; device status apc01”runs themain showprofilefollowed bydevice status apc01commands in one invocation, allowing scripted or batch execution from the management node shell.

NVIDIA Fabric Manager manages the NVLink and NVSwitch fabric resources within HGX systems, enabling efficient resource allocation, communication, and virtualization necessary for AI/ML workloads. This is critical for virtualization as it ensures optimized interconnect performance between GPUs. Video encoding, graphical rendering, or memory upgrades are outside the scope of Fabric Manager.
