Apple is building a smaller, ultra-high-security data center alongside the massive computing facility in western North Carolina where it serves up its iCloud services and other online tools, according to a local report.

The Hickory Daily Record reports that the company has filed design plans with the local government in Catawba County, North Carolina, describing a 21,030-square-foot "tactical" data center where it will house clusters of computer servers.

Permits filed with the county, the paper reports, say that the 11-room facility will include "man traps" that require entry through two security doors rather than just one and that it will be surrounded by its own 8-foot-high chain-link fence – even though Apple's Maiden site already includes its own security protections.

Neither Apple nor Catawba County officials immediately responded to requests for comment.

Opened last year, Apple's existing Maiden data center covers a whopping 500,000 square feet, and county permits have long indicated that the company planned to erect a second building on its Maiden site. But it was unclear whether this new building would operate as a data center. The company also plans to build a 24- to 200-kilowatt fuel cell plant for powering its NC operation, and many assumed that this would be housed in the new 21,030-square-foot facility – including Wired.

According to The Hickory Daily Record, Apple's plans put the price of the new "tactical" data center at $1,885,129. Previously, the company has said it will end up spending $1 billion on the site, which will also house a solar farm. When Apple announced the main, 500,000-square-foot Maiden facility last year, the company pegged its investment at $500 million.
