Bobby,

I don't understand why you would say this. One could kill a network in a variety
of less esoteric ways -- for instance  shorting two wires in the CAT5. What does
this have to do with the stability of an HA server? If (eg) an IP camera breaks
a newtork, the problem is with the camera.

It is conventional IP Best Practice to allocate servers on an at-least-
one-per-function basis. Why should HA servers deviate from what are established
best practices? An HA server is a discrete function. It is sound practice to
allocate at least one CPU to it --  not "kid gloving".

One can over-tax any machine ever built, whether by throughput, CPU cycles or
complexity of simultaneously running software. I can say from practical
experience with several different mini-ITX machines (which you have expressed an
affinity for)  that they can run out of CPU cycles with only a few HA tasks --
trying to also simultaneously run general purpose computing or networking chores
can bring them to their knees long before software interactions become a major
problem.
