I understand. But when the server goes down. All five instances go down. Which can put a company, or a department, out of business for hours or days.

If your company grosses $40 million per year you lose the cost of a $100,000 server every 24 hours you are out of business. I doubt there are too many companies using Oracle on $100,000 servers that don't make that much money annually. Tell your CFO to do the math.
