Rather than listing specific locations, OnePartner's list identifies types of places, allowing the list to be useful to anyone considering building, expanding or leasing data center space. "The goal was to give people some solid guidelines, along with some examples," says Deaderick. "The list has some really interesting examples. As we compiled the report, there were some surprises. Google Earth is a terrific research tool if you're considering leasing space in a commercial data center. As we were compiling examples, we identified a very large commercial data center that matches at least three of the 10 place types."
