You are asking that here?
HCIBench is a wrapper for VDBench. It automates VM deployments and uses VDbench to generate load and do benchmark performance testing. I have used HCIBench 1.5 and 1.6 when I am doing POCs to show customers how the same load compares between the two solutions (apples to apples). Based on vSAN growth rates, you can infer the results...
it supports on Nutanix.
