Do you want to worry about your storage system at 3 AM?

That's what all these appliances (regardless of vendor) get you for the extra cash: the manufacturers have test things out so they Just Work. Of course if you're comfortable with creating your own fail-over and redundancy system (or don't have the cash for the appliance), then there's no reason why you can't roll your own.

It's the usual trade-off: time or money.
