The vSAN ESA ( Express Architecture) Capacity dashboard provides an overview of the capacity available across all the vSAN clusters. The dashboard displays the time remaining before capacity is projected to run out, the amount of capacity remaining, the number of vSAN clusters that might fit in the remaining capacity, and reclaimable resources that can increase the available capacity.
How to Use the Dashboard
- Overall Analysis
The All Clusters by Capacity Remaining and All Clusters by Time Remaining bar charts focuses on the number of vSAN disk against the used disk capacity percentage across vSAN clusters.
- Cluster Analysis
Select a vSAN ESA cluster from the vSAN Clusters table. The detailed capacity is automatically displayed.
The Utilization widget displays the utilization for all three elements, as you need to consider all three. Network is not shown as typically it is not a problem.
The Is Storage Pool Space Utilization Balanced heat map displays individual storage pools.
Reclaimable storage is a key component of proactive capacity management. You can view details for both VMs and non-VMs.
- The Storage Pools in Selected vSAN Cluster widget displays the utilization for Disks and Disk Space.
- Like a physical array, there can be hot spots and imbalance. The Is Physical Disk Space Utilization Balanced heat map displays individual physical disks.
- VM Analysis
You can analyze individual VMs in the selected cluster from the VMs in the selected vSAN Cluster table and check their usage and snapshot. To view the trend in Usage, click on a VM. In addition, the relevant configurations of the VM is displayed.
