Re: Why choose 120 volts?

Yes - think of all the nasty partial failure cases that can be eliminated -
each entire datacenter is either up or down.  Much simpler!

Getting back to reality, I've watched more than one electrician do a
two-finger liveness test on a 120v circuit, and done it myself.  240v
HURTS, and I've not seen a pro finger it deliberately.  But I haven't
actually asked.

So when one server fails, all the rest fail too?

Doesn't even need non-standard servers - just wire them all in series.

Why stop there? Grab a 20,000 volt feeder and create a Tesla datacenter.
