The VMware administrator uses the vSAN Utilization dashboard with the vSAN Contention dashboard to manage performance.

Design Consideration

The vSAN Utilization dashboard supports the vSAN Contention dashboard. Use it to identify vSAN clusters with high utilization in a selected data center. When utilization exceeds 100%, performance can be negatively impacted, especially when a VM experiences contention. By default, vRealize Operations Cloud has a 5-minute collection interval. For 5 minutes, there might be 300 seconds worth of data points. If a spike is experienced for a few seconds, it might not be visible if the remaining 300 seconds is low utilization.

To view the common design considerations among all performance management dashboards, see the Performance Dashboards.

How to Use the Dashboard

  • Clusters Utilization.
    • It lists all the vSAN clusters, sorted by the least performing.
  • Select a vSAN cluster from the clusters utilization table.
    • All the health charts show the KPI of selected cluster.
  • Disk Groups
    • It lists all the vSAN clusters, sorted by the least performing.
  • Select a Disk Group from the disk groups table.
    • All the health charts show the KPI of selected cluster.

Points to Note

  • The vSAN Utilization dashboard complements the vSAN Contention. For more information, see the points to note in the vSAN Contention Dashboard.
