Wal-mart’s data center remains mystery local news joplinglobe.com electricity receiver

Despite the glimpses through the fence of manicured grass and carefully placed trees, the overall impression is that this is a secure site that could withstand just about anything. Earth is packed against the sides. The green roof – meant, perhaps, to blend into the surrounding Ozarks hills – bristles with dish antennas. On one of the heavy steel gates at the guardhouse is a notice that visitors must use the intercom for assistance.

Wal-Mart’s ability to crunch numbers is a favorite of conspiracy theorists, and its data centers are the corporate counterpart to Area 51 at Groom Lake in the state of Nevada. According to one consumer activist, Katherine Albrecht, even the wildest conspiracy buff might be surprised at just how much Wal-Mart knows about its customers – and how much more it would like to know.

"We were contacted about two years ago by somebody who runs a security company that had been asked in a request for proposals for ways they could link video footage with customers paying for their purchases," Albrecht said. "Wal-Mart would actually be able to view photos and video of customers paying, say, for a pack of gum. At the time, it struck me as unbelievably outlandish because of the amount of data storage required."

But Wal-Mart, according to a 2004 New York Times article, had enough storage capacity to contain twice the amount of all the information available on the Internet. For the technically minded, the exact amount was for 460 terabytes of data. The prefix tera comes from the Greek word for monster, and a terabyte is a trillion bytes, the basic unit of computer storage.

The Jane data center is an enigmatic icon to the power of data, which has helped Wal-Mart become the largest retailer in the world, and to the corporation’s growing secrecy since founder Sam Walton’s death in 1992. When Wal-Mart constructed its primary data center at corporate headquarters in 1989, it wasn’t much of a secret: It was the largest poured concrete structure in Arkansas at the time, and Walton himself ordered a third story.

"Not only had we completely designed it, we were under construction," said Bill Ferguson, a founder of Askew Nixon Ferguson Architects in Memphis, Tenn. "They were pouring foundations, and Sam walked across the parking lot one Friday at the end of the day and said, ‘You know, let’s add a third floor and put some people up there.’"

Since then, Ferguson said, changes have been made to increase the integrity of the structure. The data center was designed with backup generators, fuel on site, and room and board for a skeleton crew in the event an emergency required an extended stay.

Ferguson said his firm learned to design data centers by working with FedEx, which also is based in Memphis, and that the 1989 Wal-Mart data center was built so that it could communicate via any means available – including copper wire, fiber optics and satellites.

The data center was completed in 2004 and was part of a project that included the Supercenter, which opened early last year, and a warehouse. The resulting economic impact on McDonald County, known for its rolling hills and lazy rivers, is difficult to underestimate, said Rusty Enlow.

Enlow is chairman of the county planning commission, a body created by popular vote in 1964 but which had not met until this month. Enlow said he doesn’t know why the commission never met, but he believes it was because whatever problem prompted its creation was solved before the board was appointed. He also said he’s not sure the planning commission has any real authority, or would want any (there is no zoning in the county), but that he and the other 18 members are eager to bring even more business into the county.

Enlow was director of the McDonald County Economic Development Council when Wal-Mart quietly began scouting for land. Only after the land had been bought south of the then-unincorporated community of Jane was it announced that the project was Wal-Mart’s, and even then, plans for the data center were closely held.

But Enlow said he watched during the construction of the data center, and that it appeared to be a single-story building that was built "like a bunker," with mounds of earth piled against the sides. He later was told that it would employ 15 to 20 people, and that the building was for data storage.

To facilitate the project, the Missouri Department of Transportation agreed to widen Highway 71 to four lanes from Jane to the Arkansas line; a grant was used to expand the public water district; and the Army Corps of Engineers approved a request to fill in a small portion of wetland along Bear Hollow Road.

In April 2005, Wal-Mart used the 160,000-square-foot Supercenter to demonstrate its micro-merchandising capabilities as part of a media conference. Employees demonstrated hand-held Telxon (pronounced Tel-zon) computers, which resemble hand scanners but hold a year’s worth of a particular store’s sales history on every item. The devices help store managers decide what to stock.

Pope said she had never been asked to sign a nondisclosure agreement before in her job as assessor, and that she didn’t keep a copy. She said she didn’t appraise the building and equipment, but rather came to an agreement with Wal-Mart on what it was worth.

Pope said she did not place a value on the data stored at the building. At an estimated worth of $42.4 million, is the Wal-Mart data center at Jane important enough to the infrastructure of the state – or the country – to be on Missouri’s list of critical assets?

Albrecht is the co-author of "Spychips," about the use of RFID, or radio frequency identification devices, by the government and corporations to track individuals. She lives in Nashua, N.H., and is getting ready to receive a doctorate of education in consumer education.

"To the best of our knowledge, the only consumer-level item that is (RFID) tagged at Wal-Mart are Hewlett-Packard products and some Sanyo television sets," she said. "Now, the privacy implications of that are fairly trivial, because you’re not going to be walking down the street carrying your printer box in your back pocket."

At Brockton, Mass., Albrecht said, the company used a surveillance camera on a shelf that was linked to chips in packages of razor blades. When someone picked up a package, she said, the shelf camera would be activated. Another camera would take a mug shot of the customer at the checkout stand.

The experiments apparently were aimed at decreasing theft or for use in merchandise research, she said. "Since 1999, I’ve been working on a phenomenon called retail surveillance, which is a whole panoply of technologies that are being secretly deployed," she said. "I think most people, when they learn about these technologies, are quite disturbed. There’s a sense that when you enter a retail space, you should retain some degree of privacy."

"There’s a lot of hand-wringing about how we can find out even more about our customers," she said. "And to the extent that Wal-Mart may be creating the ability to monitor consumers by RFID and identify them by video, I’m extremely concerned. … If that’s the case, they would need that kind of data storage."

"Electronic product codes (EPCs) can best be described as the next generation of bar codes. Unlike current bar codes, which only share that a carton contains product XYZ, EPCs can identify one box of product XYZ from another box of product XYZ.

"This is possible because EPCs are powered by radio frequency identification or RFID. EPCs do not track customers. … EPCs assist retailers in more closely monitoring where products are as they move from manufacturers to warehouses to a store’s backroom.
