Not sure why you double posted this from here, especially when it doesn't involve vSAN...In any case, speaking from the position as an architect from a partner who delivers similar services, it sounds like in your case the partner/provider took the lazy route and just handed off something from VVD without doing any other leg work. Of course, there's nothing wrong with VVD and it's a solid way to approach designs, but it's not really meant as the end-all be-all approach for a customer design doc or environmental, as-built deliverable/prerequisites workbook. You may want to voice your concerns to the partner's practice manager or project manager to see what they have to say.
Thanks a lot for the comments. We have a big project with them involing all the VMware products. Looks like we have to escalate it now. Thanks again for pointing the right direaction!
