Microsoft builds first major container-based datacenter

Containers filled with preconfigured, ready-to-run servers are being touted as a quicker, more modular way to expand datacenters on the fly

Microsoft and Sun Microsystems both may claim to have pioneered the "datacenter in a box" concept, but Microsoft appears to be the first company that is rolling out container-based systems in a major way inside one of its datacenters.

At a conference in Las Vegas last week, Michael Manos, Microsoft's senior director of datacenter services, said in a keynote speech that the first floor of a datacenter being built by the software vendor in the Chicago area will hold up to 220 shipping containers, each preconfigured to support between 1,000 and 2,000 servers, according to various news reports and blog posts.

That means the $500 million, 550,000-square-foot facility in the Chicago suburb of Northlake, Ill., could have as many as 440,000 Windows servers on the first floor alone or up to 11 times more than the total of 40,000 to 80,000 servers that conventional datacenters of the same size typically can hold, according to Manos. He was quoted as saying that Microsoft also plans to install an undisclosed number of servers on the building's second floor, which will have a traditional raised-floor layout.

Microsoft's public relations staff didn't immediately respond to a request for comment Monday about the speech that Manos gave at the Data Center World conference. But James Hamilton, a technical architect on Microsoft's Windows Live Platform Services team, has posted multiple entries about the speech by Manos on his public blog.

Microsoft has said that it plans to begin operations at the Northlake datacenter by the end of the summer. The company is on a datacenter building spree aimed at meeting the sharp growth in processing demand that its Windows Live and Office Live online services are expected to generate. Other IT facilities are being built in San Antonio, Dublin, and rural Quincy, Wash., the last of which would be Microsoft's largest datacenter at 1.5 million square feet.

Cooled by the oft-chilly winds blowing off of Lake Michigan, Chicago was rated in a study conducted last year as the most energy-efficient U.S. city in which to build a datacenter. But the density of Microsoft's datacenter in Northlake is requiring the company to construct three electrical substations that will provide a total of 198 megawatts of electricity for powering and cooling systems, according to a story posted by the Data Center Knowledge online news site.

That's enough electricity to power almost 200,000 homes, and Manos told Data Center Knowledge that about 82 percent of the $500 million bill for the Northlake datacenter is going toward the facility's mechanical and electrical infrastructure.

Long used by the U.S. military, containers filled with preconfigured, ready-to-run servers are being touted as a quicker, more modular way to expand datacenters on the fly than installing racks of servers one by one. Google and Sun have both filed patent claims on server-filled containers, although the former isn't thought to be actively deploying them. Besides Sun, other vendors of container-based setups include IBM, Dell, and Rackable Systems.

Despite its huge size and 24/7 operations, Microsoft's Northlake datacenter won't provide much of a lift to the IT job market in the Chicago area. Manos has said that the new facility would employ only about 30 people, including systems administrators as well as building security and janitorial staffers. In contrast, Google has said that a $600 million datacenter it is building in Council Bluffs, Iowa, will have about 200 employees when it opens next year.

Microsoft's theory, according to a 2007 presentation by Hamilton (download Word document), is that a smaller staff will actually boost the datacenter's reliability. Hamilton claimed that between 20 percent and 50 percent of system outages are due to "human administrative error," and argued that letting malfunctioning hardware die off was a wiser strategy for a redundantly networked datacenter than trying to fix the systems and thus potentially risking a larger failure.

"As parts fail, surviving nodes continue to support the load," Hamilton wrote. "In this modified model, the constituent components are never serviced and the entire module just slowly degrades over time as more and more systems suffer non-recoverable hardware errors." He added that even if 50 of the servers in a 1,000-system module suffered fatal hardware failures, the module would still be "operating with 95 percent of its original design capacity."
