There is a short post on OCP by Charlie Manese, Facebook Hardware Design team on Serviceability and operational efficiency, so I will just put the whole thing up.
Know the guys at Google have this data, wonder who else does?

At Facebook, because of our scale, we require that solutions deployed in our data center be engineered for maximum operational efficiency and serviceability.
The data center team works closely with the hardware design team to ensure this. Our designs incorporate features such as front-of-rack serviceability, toolless repair operations, and simplicity.
We’ve completed time-in-motion studies, streamlined processes for inventory and repair, and have developed scorecards to that help us evaluate and compare different hardware solutions.
Below is a table of the time-to-repair comparison of different kinds of web servers that have been deployed in our environment:
If you're interested in learning more about how Facebook thinks about serviceability and operational efficiency, and you missed the original event, I'll be joining a Hyve webinar on October 24, 2013.
