Facebook also makes the switches: Wedge, the open source switch

Facebook also switches and announced the top-of-rack switch called Wedge and equipped with its own Linux-based FBOSS operating system.

The undisputed leader of social networks also wants to have a say in the data center network infrastructure sector. The first prototypes are already ready

By Fabio Bossi

During the recent Gigaom Structure Conference, held in San Francisco at the end of June, the company of Mark Zuckeberg announced that it had concluded, under the Open Compute Project (OCP), the development of the top-of-rack switch called Wedge and equipped with its own operating system, FBOSS, obviously based on Linux. The design of the switch was attended by companies of the caliber of Broadcom, Intel, Mellanox and Accton, while Cumulus Networks and Big Switch Networks contributed to the creation of the software part. The project of the new switch, of which some prototypes have already been put to work in the Facebook datacenter, it will be made available with an open source license by the end of the year, if everything goes as planned, and therefore it can also be adopted by other companies that do not have the resources necessary to develop their own systems. The SDN philosophy (Software Designed Networking ) of the Wedge switch provides for the separation of hardware and software in order to make the device more flexible, scalable and efficient. Equipped with 16 40 Gigabit / s moon Ethernet ports, expandable up to 32, the Wedge switch includes two power supplies in one chassis, one standard Application Specific Integrated Circuit (ASIC) with network interfaces and a microserver, specifically based on of a Group Hug card always realized within the Open Compute project. All the components of the switch, as well as its chassis, can be replaced with elements sized according to different needs, thanks to its modular design.wedge "width =" 150 "height =" 150 "srcset =" 150w, https: //www.digitalic. it / wp-content / uploads / 2014/07 / wedge-300x300.png 300w, 1024w, https: // 360w, 750w " sizes = "(max-width: 150px) 100vw, 150px" /> For example, in the first prototypes the Group Hug a model equipped with an Intel processor, but thanks to the all-round form factor of this project it will be possible to adopt solutions based on a wide range of Cpu, including those produced by AMD and those based on ARM architecture. From the software point of view, on the other hand, the Linux-based FBOSS operating system actually makes the switch an additional server (which could even be based on the same hardware as the it connected), which as such can be monitored and gestures exactly with the same methods. This solution makes it possible to optimize the use of network connections, to resolve problems more easily and to react very quickly to sudden changes in network traffic. In Wedge's announcement that Facebook published in one of its blogs it was in fact underlined how, thanks to its particular technology, the new switch has allowed to increase by 90% the traffic in the perimeter network resources of the datacenter. For now the traditional vendors of the sector do not have shown particular concerns following Wedge's announcement, although several analysts say the Open Compute switch could threaten part of their business. The executives of Cisco System and Juniper Networks, two of the companies that could suffer the most from the development of the project, stated that the Wedge switch carries hidden costs and that it can only be of interest to a limited number of users, those with infrastructures very large, if not gigantic, like those of giants such as Facebook, Google and Amazon.</p>
