When to use VMWare over free hypervisors?

I would think they certainly could mandate that, but, what seems obvious is that they shouldn't be telling the company how to get there. That is IT's job.
They CAN make that mandate and everyone under them has to follow it. But making that mandate means a few things:
- The board is now running the IT department direction. That's insane. Who pays the board members to run an infrastructure department.
- Things like this are never mandates in business. Business and mandates don't go together, they are opposing concepts.
- Boards doing this mean, by definition, that they are going against their own mandate of representing the business. Mandate is another way here of saying "not acting ethically."
- How does the board realistically have the tools at their disposal to know when a decision like this is viable?
- If the people above the CEO are doing the job of the people in the trenches, what are the rest of the employees for?
- Imagine if the stock holders started doing stuff like this, it would sound crazy, right? It's crazy for anyone to do this, whether it is the CIO, CEO, Board, Chairman, Shareholders.... none of that makes sense. The higher in the stack you go, the crazier it gets.

We also need HA, not just for this, but because its a business decision from the board on the level of service they want to provide. So...
So it is REALLY important to then realize that the board is running IT. They are not a true board, but actually hands on techs at that point. They are the acting IT department. Nothing particularly wrong with that, but really weird for decisions like that to be taken on by a board.
Now this is where I question Scott.
Is it not ok for the board to mandate 99.999%+ setup?
No. It's not doing their job as the board, it's not doing their legal responsibility to the investors. It's a business failure and potentially a legal one.
Exceptions: When life outranks the fiduciary mandate of the business.
Right, duh what was I thinking? They can't ask for this in a vacuum. They have to know the cost v benefits to make sure it makes financial sense.

And my comments, board should be replaced by company management team, the Cs.

Exactly. If they did analysis and knew that it made sense, they'd still be being ridiculous and doing IT's job for it, but they would not deliver a mandate but rather a cost/risk analysis that would say when HA made sense and at what cost. It would never be HA of X level at unlimited cost.
There are ways for the board to take over IT, but if they do it, they should do it well. Taking over IT is weird, but you can make an argument for a case for it. But taking over IT and doing something that normal IT people would be considered failures for having done (not doing the one most important job IT is there to do - the analysis) is pretty bad all around. Failing at being the board, failing at IT all at once.

The Cs shouldn't do it either. You just expect the board to know even moreso than the Cs not to make a mistake like this. But really, even the people in the trenches should know that mandates make no sense, because if they don't realize that a mandate like that can't work, how do they do their own jobs?

Got it

@stacksofplates like let the san use uts own snapshot/backup sw?
Yes, which isn't quite fully offloaded, but a reliable means of communications so that the SAN can do the majority of the work.
Actually vVols is different than SAN Snap-ins in how snapshot offload is done. VMFS snapshots do not exist at all in the case you use them. You also get a management, and command integration so you can set compliance requirements (encryption, retention, replication, performance minimums) and apply policies automatically (using OpenStack, VCD, vRA etc) and it will validate that those configurations are continuously met and alert if not. Nifty stuff.
