Apple’s data center in Maiden, N.C., will be accompanied by a second, smaller data center, reports the “Winston-Salem Journal” (http://macte.ch/oICBR).

According to Apple’s design plans on file with Catawba County, the new 21,030-square-foot data center, also referred to as a “tactical” data center, will store clusters of servers. Permits filed with the county list the cost of the new 11-room data center at $1,885,129, notes the “Journal.”

The article adds that an electrical permit on file refers to the building as a “non-occupied equipment building.” Rick Frady, building services chief for Catawba County, told the “Journal” that a non-occupied building just means it’s not open to the public. He said the future building was described to him as a stand-alone metal building with a concrete pad.

Last year it was announced that Apple would build a data center in Catawba County on the outskirts of Maiden. Maiden and Catawba County agreed to US$7.3 million in incentives for Apple in order for them to build the center there. The company will build a 500,000-square-foot facility along U.S. Highway 321.
