Liebert was just the manufacturer of the environmental controls/HVAC. They're pretty much the standard in precision HVAC and data centers it seems.
And you are right about the time and money spent figuring all this out. I was at their data center looking at their infrastructure, taking down model #'s, measuring, etc, for almost a whole day. Then it took another 3 weeks of buying hardware, testing it, seeing what made it overheat, measuring power consumption under different loads, etc.
In retrospect the company could have bought me a new 4-door sedan with the money spent on this project. But the thing is that just Having a second rack in a data center is a $1000/mo proposition (on average). Having a single 20-amp circuit is a $400/mo deal. It all add's up real quick, specially when you are paying premium boku rates for the facility.
