LinkedIn pumps water down to its server racks, uses an interesting spine and leaf network fabric


It takes a lot of horsepower to support LinkedIn’s 467 million members worldwide, especially when you consider that each member is getting a personalized experience, a web page that includes only their contacts. Supporting the load are some 100,000 servers spread across multiple data centers.  To learn more about how LinkedIn makes it all happen, Network World Editor in Chief John Dix recently talked to Sonu Nayyar, VP of Production Operations & IT, and Zaid Ali Kahn, Senior Director of Infrastructure Engineering.

Lets start with the big picture view of what you have for data centers around the world.

Nayyar:  We have three main data centers in the U.S. that serve LinkedIn.com worldwide, one in Richardson, Texas, one in Ashburn, Virginia, and a new one in Oregon that we just launched. We have a smaller data center in Singapore that we launched earlier this year, and its main purpose is to improve our member experience in APAC.  It has basically a complete set of data but it’s only for our members in APAC.  All four are connected by our MPLS backbone and 13 global points of presence (POPs). 

Are they all of similar architecture, or a mix given they were built at different times?
