IOPs Capacity

[joeflint]

Hi, i have questions around IOPs.

(1) On VSAN how can one calculate the IOPs capacity on an individual ESXi host and the entire vSAN cluster?

(2) The same question for ESXi hosts using array based storage?

Is there a formula or documentation available how to do this?

I have a customer asking for numberous VMs with various IOPs requirement, and need to find a way to review IOPs capacity

thanks

The definitive way would be to run a storage benchmark application, test under various conditions and configurations, and observe the results. HCIbench is a popular one.
