POSTER: computer news   ||   FACEBOOK IS DEVELOPING A PROPRIETARY SWITCH PORTS 100G	DATE:2015-11-22
Facebook, like other giants of the market data processing centers (DPC), a significant part of the equipment developed independently.  This allows  to create solutions for specific tasks and is not dependent on suppliers.  It is interesting to note that in this of Facebook went further than others.  It does not just create a platform, it makes them open and accessible to copy by others.   Currently, as reported by Facebook, the company's engineers are designing switches with 100-Gbit / s ports Ethernet.  According to the plan of the company, the cost of each 100-Gbit / s ports should be reduced to $ 1 / GB.  To do this, the developers simplified specification standard Ethernet 100G to the range of 500 meters instead of   2 km and reduced requirements for the working temperature and lifespan platform. At the heart of the new switching platform Facebook Wedge 100 is a switch Broadcom Tomahawk with an aggregate capacity of 3.2 Tbit / s.  Any such decision will use 32 100 Gb / s port.  Prior to that the company will continue to use Facebook Wedge 40 switches with 16 ports of 40 Gbit / s (sample design in the picture above).  The capacity of the modern industry-standard 400G runs at full capacity, data center owners complain.   Related Products :
