Facebook has made the Wedge 100 with a bent toward toollessness and hot-pluggability. Facebook has thousands of these switches in operation across their data centers and if they need to be serviced, it has to be done quickly.

While the Wedge 100 uses some of the same hardware as the Wedge 40, it has been changed to address pain points in the previous version.įrom a hardware side, the Wedge 100 is all about serviceability. While the Wedge 100 replaces the Wedge 40, it is still backward compatible with existing 40G devices and uses the same FBOSS and OpenBMC software. The reason for this, is so they can replace hardware or software with newer, better technology as soon as they need to. That being the case, Facebook uses fully open and disaggregated hardware.

Facebook is now announcing that the Wedge 100 specification has been accepted by the OCP and brings Facebook one step closer to its goal of 100G data center.įacebook is one company that when it changes a good portion of the world notices. At the time Facebook had opened up the design of the Wedge 100 to the Open Compute Project (OCP). In March of this year, Facebook announced its Wedge 100 top of the rack (TOR) switch.
