Apple has filed its master plan for its data center facility in Prineville, Oregon. The San Francisco Chronicle reports that the plan shows two buildings with more than 500,000 sq. ft. of “data halls”; the overall facility is expected to cover about 107 acres. No time table is given in the plans for construction. “They really didn’t say how long they are looking at,” Prineville senior planner Joshua Smith said. Apple is already building a 10,000 sq. ft. data center on the Princeville property it purchased in February.
