Facebook server secrets opensourced

first_imgIf you work in corporate IT, or you just share an affinity or passion around high-end server technology and datacenter infrastructure, you’ll be pleased with Facebook’s latest move. The company is opening up on its datacenter design, sharing everything from the manufacturer, make, and model of the servers that keep Facebook online and available at all times to the way its datacenter is powered and cooled to keep those servers running happily.Part of the initiative is to give Facebook fans an eager look behind the curtain of how the social networking behemoth runs its operations and who’s technology the company leverages, but also to give other people who work in corporate IT an indication of what it takes to keep an operation as massive as Facebook up and running.For starters, Facebook’s servers are made almost entirely by Rackable Systems, a company that designs and builds custom servers and the racks to hold them (if you want something that’s not mountable in a standard 42 U rack.) Rackable Systems – which acquired Silicon Graphics, Inc. and took its name in 2009 – has long been a leader in custom server design and manufacturing, as well as its legacy products including RapidScale (TerraScale/TerraGrid) hybrid server and storage solutions.Facebook is working with the company to build custom Intel and AMD-based servers that are modular and have easy-to-swap components. The servers themselves snap together using clips and holes instead of screws and bolts, and feature a 1.2 mm zinc plating with no logos or other branding on the outside of the server. If you walked into a datacenter full of Facebook servers, you would likely see racks upon racks of gleaming zinc plates.Facebook’s servers feature a mix of Intel Xeon 5500 and 5600 quad-core processors (server-class versions of the last generation of Core i7 processors) and AMD 8 and 12-core processors. The servers also have switchable, dual-mode power supplies that can draw power over A/C and D/C.All of these servers are in a datacenter that’s designed to be modular and environmentally friendly. Facebook opened up its datacenter design to the public as well, including the power and cooling designs of its racks and cabinets, the battery backups in each rack, and the motion sensitive LED lighting in the datacenter that only lights up the areas where technicians are working. Facebook is even using the warm air piped out of the datacenter to heat their offices and the outside air when it’s too cold in the vicinity.Overall, Facebook has shared information about the way their datacenters are built, the design of their racks and cabinets, the technology that makes up their servers, and more. Facebook’s goal is to help other businesses build energy-efficient technology infrastructure.Read more at GigaOmlast_img read more
