The exterior of the QTS Metro Atlanta data center.

With 990,000 square feet of total enclosed space, the QTS Atlanta Metro Data Center is one of the world’s largest data centers, with its own on-site Georgia Power substation. The site is currently in the third phase of a multi-year expansion that will more than double its original 200,000 square feet of raised floor space. This video from QTS (Quality Technology Services) provides a look inside the huge facility and the infrastructure that keeps it humming.
