True, but it's a jugging/balancing act, and you *have* to get it right.

If an HA solution that only handles a maximum of two nodes is fine for 
you, then a pair of Linux boxes running DRBD may be enough, but what if 
you need more?

Or have a requirement for geographically separated systems, to handle 
big-time worst-case stuff.

Of course the low-cost solution can work, but it's not always simple.
