Inside Ten of the World’s Largest Data Centers

Data centers touch all our lives. Businesses rely on data centers to house mission critical information and run operational initiatives across the organization.Today’s largest data centers feature state-of-the-art technology, operation rooms spanning thousands of square meters, and are required to hold billions of pieces of customer and business information. As demand for cloud services increase these centers comprise tens or sometimes hundreds of thousands of servers, multi-petabyte storage systems and increasingly are situated in locations where cheap energy is plentiful.

In pictures, here is an inside look at ten of the world’s largest data centers.

Microsoft’s Quincy Washington Data Center

The recent NY Times data center technology slideshow illustrates in photographs just how impressive data centers are and how important they are to our day-to-day lives.

As servers become more powerful, more kilowatts are needed to run and cool them. Data centers worldwide now consume more energy annually than Sweden.

Inside Facebook’s Data Center

Inside Facebook's Data Center
Facebook’s data centers store more than 40 billion photos, and users upload 40 million new photos each day – about 2,000 photos every second. Via Data Center Knowledge, “Not surprisingly, the racks are packed.”

1&1’s Data Center

1&1's Data Center
Via InformationWeek, 1&1’s data center is in Lenexa, Kansas, just outside Kansas City, the second largest railroad hub in the U.S. Five server rooms hold 860 racks and can accommodate at least 40,000 servers.

Inside a Google Data Center

Awarded a patent on a portable data center modeling in October 2008, Google’s data center features a “container hanger” filled with 45 containers, holding up to 1,160 servers each, and uses 250 kilowatts of power. Referred to as Data Center A, it spans 75,000 square feet and has a power capacity of 10 megawatts. (Information courtesy of Data Center Knowledge)

San Diego Supercomputing Center

Via NetworkWorld, San Diego Supercomputing Center’s new building features cool concrete exteriors, special windows treatments and windows that actually open. This image illustrates how by using robotic virtual tape libraries, SDSC is able to reduce energy costs.

Building a Data Center in 26 Weeks

Digital Realty Trust Data Center Project
Digital Realty Trust builds data center facilities all over the world. This photo gallery on Flickr provides a look at its data center construction process for their site located at 1201 Comstock in Santa Clara, California.

Who are we missing? Surely companies like Amazon and eBay should be on this list, though we had trouble verifying the authenticity of data center images found online. We’d love to hear about data center images and links we missed via the comments below or send Wikibon a message on Twitter!

Update – March 26, 2010

This came in from the back channel.

Recovery Point’s Multiple Miles of Chiller System Feeds

Miles of Chiller System Feeds

This is a shot of some of the miles of chiller system feeds that sit under the raised floor of a Recovery Point data center used to host dense blade servers. The design and construction has achieved Uptime Institute’s Tier III level certification and provides a redundant and concurrently maintainable infrastructure. This means that the servers never have to come down for maintenance, and the infrastructure can be maintained while the chillers are still running.

  1. I thought this article was about the world’s 10 largest data centers? It is entirely inaccurate. You mention NJ2 in Weehawken, NJ, but what about 60 Hudson in Manhattan? 60 Hudson is way bigger than this place. 1&1’s facility is mentioned with 860 racks, but I can count at least 20 facilities just in the U.S. that hold more than this. I work in DC’s around the country for a living and I can assure you that most(all?) DC’s on this list are by no means the largest facilities in their respective country, much less the world. I can’t account for some of these private DC’s since I have never seen them, but looking at the numbers there are few on this list that I would say may actually qualify.

  2. Send pictures and we’ll update it.

  3. Most data centers will revoke your access for taking pictures or recording video of anything, period. In fact, most will ask you at the door if you have any cameras or video recording equipment at the entrance. This is to protect other customers equipment or particular setup from being recorded by a competing company and for security. If you can get me permission to take pictures inside 60 Hudson or any of the various Equinix and Coresite facilities around the U.S., I’d be glad to provide pictures of very large DC’s.

  4. Wow! This is bigger than the Kansas City Colocation centers I know but these data centers belong to really huge companies anyway. I wonder how much it would cost to host your stuff there lol
