Two or more people for throughput -- in parallel.  But do you use two people 
to rack a 1U server?

I find that racking a ~32-35 lb. 1U server into position U42 is fine.  In 
fact, at my height (6'4" tall), position U30 is probably the hardest 
location. :)   I've found that sufficient height, decent strength, and good 
physical coordination are important, but otherwise it's never been a 
problem.  Don't know what OSHA would say. :)

Oh wait, are you talking racking without rails?  Yeah, that almost always 
takes two people no matter what the weight or height.

I've never worked with a 50U rack so can't comment there.
