Facebook's datacenter footprint is constantly growing to adapt to the vast amount of new services we provide to people. This results in a dramatic scaling challenge that our engineers have to deal with on a daily basis. Not only do we need to build and evolve the physical infrastructure that connects myriads of servers together, but also ensure that the network is running smoothly and meets strict performance goals. And with the introduction of our own switching software and our networking products we have entered into a new era of unprecedented opportunities to re-think traditional networking and iterate quickly in an area that was previously very closed to innovation. Network Engineers at Facebook are hybrid software/network engineers who ensure that Facebook's network and related services run smoothly and have the capacity for future growth. Infrastructure Network Engineers are focused on Cooling, Space, Power, and Fiber, and how to scale those in the right combination to support the growing and evolving network requirements. This infrastructure needs to be supported by systems and tools that allow for accurate planning for both network growth as well as providing the signal needed to initiate expansion of the infrastructure sufficient time to build it. To be successful, an understanding of electrical, cooling, and fiber connectivity as it applies to networking gear is a requirement.
