"How will Uptime Institute measure reliability in its new Tier classifications? Will they take IT load and power equipment compliance to the ITIC/CBEMA curve into account? This is the only published IT load vs. input power comparable I could find. "

"I'm mot sure Uptime "measures" reliability, as that's scientifically difficult - watch the center for a thousand years and measure how much downtime it has? - it's more assessing the reliability according to specific best practices.

Efficiency is easier to measure, and they didn't say how that will be measured. "

"I've seen interesting videos about data centers (I found some at torrent SE http://www.torrentbasket.com ). They get more and more popular. As for me, I also think that they become more and more efficiant each year."
