semi-OT: power requirements

[ted leslie]

I have this "dooh oppp" moment happen a couple times over all my years.
You have your available power, and you add your machines (over time, if by that,
even over hours), all is good.
Then one day perhaps a year later, you have a power outage,
and then for the first time all those machines start up at 
exactly the same time, and all the HD load up (on power) at the same time,
and pop goes the breaker(s), which at first you think, this is odd, it ran fine before!
so remember to factor in initial higher load on turn up of all the stuff.
