I recently shared on how you can deploy the latest VMware Cloud Foundation (VCF) 5.1 release with vSAN Express Storage Architecture (ESA) using Nested ESXi and leveraging a custom vSAN ESA HCL JSON file, which I had created to workaround the required vSAN ESA pre-check during the VCF Bringup process.
I will admit, I actually did not the create the custom vSAN ESA HCL JSON file manually, it was auto-generated using automation 😉
My initial goal was to make it easier for anyone to play with VCF 5.1 using both Nested ESXi as well any physical system that is capable but may is not on the official VMware vSAN ESA HCL. After a lot of trial and error testing with Nested ESXi, I finally had a functional PowerCLI script that can then be used to run against a standalone ESXi host to dynamically generate a compatible custom vSAN ESA HCL JSON file that can then be used with both VCF 5.1 with vSAN ESA or even a standalone vCenter Server deployment for vSAN ESA enablement.
