Surveying the World of the Biggest Server Farms

1sockchuck writes "Rackspace said this week that it is managing more than 50,000 web servers, raising the question: who else has that many? Of companies that publicly discuss their server counts, there are only a handful that are near or above the 50,000 server mark, including 1&1 Internet, The Planet, and Akamai, as well as Rackspace. The larger totals are found among companies that don't discuss how many servers they're running. The leading suspects: Google, Microsoft, Amazon and eBay."

Shouldn't it be easy to figure out?

Figure servers per sq ft and add up their total datacenter sq footage. Googles a bit harder due to changing strategy over their current server lines but a good guesstimate shouldn't be too hard.

Should still get you in the right ballpark, few companies are going to waste huge amounts of money building empty datacenters =)

Many of the production data centers I've worked on have been using VMs for web servers for quite some time (e.g. ESX 2.x). That includes one of the companies that is on the list of unknowns in the article. I'm surprised it wasn't addressed and that so many jumped to a physical server conclusion. However, even if the 50k servers are all VMs, that's a major management load. 50k of just about any configuration item takes some work.

A lot of datacenters get built in repurposed buildings - the square-footage is often misleading (some are even 60's era compute farm housing - 90% of the space may be unused.)

For low-latency datacenters, you build in the middle of cities. Then you find square-footage really doesn't cover it: the fire-marshall shows up and red-tags you because he doesn't want a six mega-watt dense power sink in the middle of his premium real-estate.

Also hopefully they are not counting virtual machines here.

It's almost guaranteed that they are talking virtual servers as well as some bare metal. Rackspace is talking about the 50,000 web servers that *THEY* manage--i.e. managed services. This figure likely doesn't include the thousands of rented colo machines which their customers manage themselves. The latter was Rackspace's first business model, a pure colo. It wasn't until relatively recently that they started offering managed services. It may very very turn out that the 50,000 server figure is the entire sum total of physical servers on their network.

4 years ago. I wonder if all those boxes are still running right now? I wonder what google does when it retires servers.....it would be kind of cool to have a couple of bonafide google racks doing something cool at my house.

Most of them won't go into detail, but Wall Street firms have immense server farms. Some of them are limited in size by the amount of electricity the New York City power grid can supply them. They also have huge data centers in less prime real estate, but microseconds are dollars in the financial markets, so they try to keep as many of their systems as close to the action as possible. There are entire floors of NYC skyscrapers full of racks modeling the financial markets in real time, conducting transactions, and crunching numbers for human analysts.
