I just want to counter this one point.  POWER9 is absolutely not power
hungry.  I've seen the 8-core chips idle at under 10W, with active loads
maybe in the 40-60W range.  We're dogfooding one machine in a typical
office setting, and it dissipates nearly no heat -- it's using less
power than the older Xeon it replaced.
