GPUDirect Storage performance relies heavily onRDMA-capable network hardware and proper configurationto enable direct memory access between storage and GPUs, bypassing CPU involvement for faster data transfers. Therefore, the first troubleshooting step should be to verify that RDMA-capable hardware is present and correctly configured. Adjusting GPU clocks, CPU speed, or GPU memory does not address the fundamental networking requirement for GPUDirect Storage.

In NVIDIA AI infrastructure, theNVIDIA Fabric Managerservice is responsible for managing GPU fabric features such as NVLink partitioning on HGX systems. This service periodically polls the GPUs to monitor and manage NVLink states. By default, the GPU polling subsystem is set toevery 30 secondsto balance timely updates with system resource usage.

This polling interval allows the Fabric Manager to efficiently detect and respond to changes or issues in the NVLink fabric without excessive overhead or latency. It is a standard default setting unless specifically configured otherwise by system administrators.

This default behavior aligns with NVIDIA’s system management guidelines for HGX platforms and is referenced in NVIDIA AI Operations materials concerning fabric management and troubleshooting of NVLink partitions.

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.
