I would not be quite so quick to discount a SAN. We have
just received ours and I am adding to our cluster after 3
months of testing. I have worked hard for almost a year
to get one in.
You can build as much complexity as you want into it-but

with sufficient spares, and the Linux heads we get and can

Speaking from experience?
The expectation when building a fail-over system is that the systems
is higher even though the mtb-partial-f is shorter (more parts that can
Of course the probability, that the failover logic / software is the new
is not zero either.
