You rarely need to fail over to the passive system.
And management will never, ever let you do a full-up test, nor will they allow you to spend the money to build a scaled-up system which can handle the full load, because they can't stand the thought of hardware sitting there gathering dust.

Active/passive is an obsolete 35-year-old mainframe paradigm, and it deserves to die the death. With modern technology, there's just really no excuse not to go active/active, IMHO.
There's always one good reason: money. Some things just don't active/active nicely on a budget. Then you're trying to explain why you want to spend money on a SAN when they really want to spend the money on new "green" refrigerators. (That's not a joke, it really happened.) ~Seth
