Facebook Ops: Each Staffer Manages 20,000 Servers

Delfina Eberly,  Director, Data Center Operations, Facebook, presented the Tuesday morning keynote about optimizing data center operations. In terms of hardware, Facebook, because it runs such an enormous volume of servers, focuses on serviceability, including starting from the ground up by influencing server design to ensure easiest and least time consuming methods to repair equipment in the data hall.

That includes the scalability of the people that work in the company’s data centers. Each Facebook data center operations staffer can manage at least 20,000 servers, and for some admins the number can be as high as 26,000 systems, according to Delfina Eberly, Director of Data Center Operations at Facebook. Eberly was the keynote speaker Tuesday morning at the7×24 Exchange 2013 Fall Conference, speaking on “Operations at Scale.”

Facebook’s perspective on serviceability and operational efficiency

Time to repairBy Charlie Manese, Facebook Hardware Design team 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.

Facebook throws down efficiency gauntlet with real-time data and open-source dashboards

Facebook's Power Usage Efficiency (PUE) and Water Usage Efficiency (WUE) dashboardWhen I first visited Facebook’s data center in Prineville, Ore., in 2011, I felt privileged to spot some figures on the facility’s power-usage effectiveness (PUE) on a screen affixed to a wall. The PUE number, which gives a sense of how much of the energy gets consumed by computing gear, wasn’t exactly what some reporters wanted to know — total number of megawatts would have been better than PUE, and that sort of information came later — but it was a start toward transparency. Now, the PUE data won’t be such a big deal to catch a glimpse of anymore.
