Facebook Erects Supercomputers With Giant Stacks of Mac Minis
BY CADE METZ 12.06.13
If you walk into one of the massive data centers that underpin Facebook’s ever-expanding online empire, you’ll find tens of thousands of computer servers. Many of them are designed by Facebook, and most run Linux, the open source operating system that drives so much of the modern web. But those aren’t the only machines you’ll find.

You’ll also find Mac Minis. Lots and lots of Mac Minis.

The Apple Mac Mini is a small, square computer sold without a display, keyboard, or mouse. It looks kinda like a makeup case with an Apple logo on it. The thing was conceived as a home machine. You could toss it onto your desk and attach peripherals already lying around the house. But nearly a decade after its debut, the Mini has assumed a very different role at Facebook. Mark Zuckeberg and Co. operate a vast fleet of Mac Minis so they have a place to test the Facebook iOS app — the app that lets hundreds of millions of people use the world’s most popular social network from the iPhone and the iPad.

This is all well and good, but by god the iOS FB app isn't very good, is it?

How are they getting the Infiniband cables connected to get the low latency (200 nanoseconds) and high data throughput (up to 300Gbps)?
