Hi,
SQL Express support 5 ESX host and 50 virtual machine. However you have 58 virtual machine. In your initial post you have mention " 30 VMs with their replicas been managed by the vCenter Server" what does this mean ? Are this back of virtual machine taken using Veam ?
1. How frequently backup is schduled.
2. Do you see any frequent task in vCenter "Task/Event" , any messages that occurs frequently.
3. To ensure that the default Statistics Level is set to 1:
- Using the vSphere Client, log into vCenter Server as an administrator.
- Navigate to Administrator> vCenter Server Settings> Statistics.
- Under Statistics Intervals, ensure the Statistics Level column is set to 1.
- To change the value, select the Interval Duration, click Edit and select Level 1 from the dropdown.
