vSphere 8.0 Update 3 introduces a new vSAN Data Protection capability for the vSAN Express Storage Architecture (ESA) and it is currently delivered as a standalone VMware OVA (see Duncan's post in case you are wondering where to download) which, once deployed and configures, enables a new vSphere UI plugin as shown in screenshot below.
After going through the manual (vSphere UI) deployment workflow, which also included some non-traditional input like requiring the raw vCenter Server TLS certificate, I was interested in automating the deployment using PowerCLI.
