21. “We are pushing 50kW a rack,” said Richard Donaldson, the Director of Infrastructure Management and operations at eBay. 

22. LinkedIn Hyperscale Data Center
“We took our data center through a transformation,” Yuval Bachar, LinkedIn’s principal engineer of global infrastructure architecture and strategy, said. 
Designed for simple scalability
They can go from running on tens of thousands of servers to running hundreds of thousands of servers.
Just below 18kW per cabinet currently
32kW rack potential
Key factors:
Server, power, and space costs associated with leased data center space
Why ChilledDoor
“The decision to use a high-density design was made after a detailed analysis of server, power, and space costs. It turned out high density was the most optimal route for LinkedIn,” Yuval Bachar, LinkedIn’s principal engineer of global infrastructure architecture and strategy, said.
