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.
