Managing High-Speed Fabrics#
The high-speed InfiniBand fabrics are managed with NVIDIA Unified Fabric Manager (UFM). UFM is a powerful platform for managing scale-out computing environments. UFM enables data center operators to efficiently monitor and operate the entire fabric, boost application performance, and maximize fabric resource utilization.
While other tools are device-oriented and involve manual processes, UFM automated and application-centric approach bridges the gap between servers, applications, and fabric elements, thus enabling administrators to manage and optimize from the smallest to the largest and most performance-demanding clusters.
The dashboard for UFM is shown in Figure 14.

Verifying that UFM is Running#
Use the service ufmha status command to verify UFM is running:
1ufm001# service ufmha status
