I have been on a search for documentation of VCF 9.1 deployment and I found the most detailed on yet!
Her name is Leaha and she is very active in updating her documentation and she is also working on creating a blog for people with homelab who could consolidate the requirements of VCF deployment in terms of usage and add-ons.
Would recommend a 100% to go have a read through her blog for VCF 9.1 deployment
