We have grown from a handful of regions to 15 locations around the world. Even as the demands increase, we are bound by hard physical constraints of power and optics supply availability. Because of these dual pressures of increasing demand and physical constraints, we decided to rethink and transform our data center network from top to bottom, from topologies to the fundamental building blocks used within them. In this post, we’ll share the story of this transformation over the last two years.

Pirlo was designed to eliminate and automate many of these manual processes. In this post we will describe Pirlo, a flexible system designed to validate and configure network switches and to ensure the reliability of servers before they enter production. We will explain the design of Pirlo and its components, and show how some of the design choices we have made enable Dropbox to manage our physical infrastructure operations efficiently and safely.
