How do I interpret NVMe over InfiniBand statistics?

Contributors

The View NVMe over Fabrics Statistics dialog box displays statistics for the NVMe subsystem and the NVMe over InfiniBand interface. All statistics are read-only, and cannot be set.

  • NVMe Subsystem statistics — Shows statistics for the NVMe controller and its queue. The NVMe controller provides an access path between a host and the namespaces in the storage array. You can review the NVMe subsystem statistics for such items as connection failures, resets, and shutdowns. For more information about these statistics, click View legend for table headings.

  • RDMA Interface statistics — Provides statistics for all NVMe over Fabrics ports on the RDMA interface, which includes performance statistics and link error information associated with each switch port. For more information about the statistics, click View legend for table headings.

You can view each of these statistics as raw statistics or as baseline statistics. Raw statistics are all of the statistics that have been gathered since the controllers were started. Baseline statistics are point-in-time statistics that have been gathered since you set the baseline time.
