Ebay will formally open a new data center in Phoenix in two weeks that will use free cooling despite the city's notorious high temperatures.

Temperatures in Phoenix, Arizona -- one of the most arid places in the U.S. -- routinely exceed 100 degrees Fahrenheit (38 degrees Celsius). That's about the opposite of the typical cool-weather environments companies often choose to build data centers.

But in about two weeks, eBay will formally open its latest data center there, a facility the company hopes will be used for as long as 20 years.

"Who would want to build a data center in Phoenix?" asked Mike Lewis, director of eBay's Mission Critical Engineering. "Yes, it's hot."

EBay already has a facility next to the latest data center, which was a project "Mercury," said Lewis, who spoke at the DatacenterDynamics conference in London on Wednesday.

It started with a two-floor warehouse that was intended to store and test equipment for the existing Tier 4 data center next door. But that facility was filling up, "so we decided may we will turn this [warehouse] into a Tier 2, lower-cost facility," Lewis said. Staff from the existing data center would run both facilities.

Lewis said eBay wanted to build a facility that could be quickly expanded with minimal impact on the company's operations. It wanted parts of the data center to be different tier categories. It also wanted it to be as dense as possible, with the ability to place containers containing server racks on the roof and get those containers running within 24 hours.

EBay put out 50 requests for proposal and received 17 responses, which Lewis described as harnessing talent and brain power "for a problem honestly we didn't know how to solve."

The company's selected contractors came up with a design for a six-megawatt facility that would could be upgraded to 12 megawatts, with an ability to increase that capacity in two- megawatt increments, Lewis said. It has about 7,000 square feet of main server space, with 7,000 square feet of space for containers on the roof.

To speed up deployment of new server racks, eBay has been working with vendors and rack manufacturers on a concept Lewis called "rack and roll."

Rather than eBay doing the early configuration work, it is ordering racks to specification, where a vendor fills the rack with servers, does all of the cabling and labeling and loading of the OS. Then it goes to eBay, which can have it configured with its own applications within four hours.
