A data center company will convert a former fab near Dallas into a massive data center that will offer between 700,000 and 1.4 million square feet of server space. The company, QTS, followed a similar path with a huge former Qimonda facility in Richmond. In Silicon Valley, Facebook's servers live in an old Seagate plant converted by Fortune Data Centers. Up in Oregon, a former Hynix chip plant is becoming a data center. These facilities offer several attributes that make them good covnersion prospects: lots of existing power and cooling capacity, with raised floor already available in many faciltiies. Data center companies says this existing infrastructure saves them money, leaving less to retrofit.
