Google launches 10 Gbps optical routers

Google engineers do-it-yourself build servers running on a unique operating system and proprietary file system. Commercial software in Google data centers is almost never used, and standard open source programs change beyond recognition. The company aims to optimize each element in the infrastructure of data centers to maximize productivity. They redo everything they can . Now it came to the routers that are needed for communication between servers.

There is information that Google engineers have begun to develop high-performance routers on their own technical characteristics, which do not correspond to any device on the market. It is possible that they have already started installing new routers in data centers. All this is done in secret.

Judging by the components that Google has been making in bulk for several months, the company releases 10GbE routers on Broadcom chipsets. It uses optical transmitters SFP +, which are also purchased in large quantities. Most likely, the 20-port Broadcom BCM56800 model was chosen as the platform.

According to preliminary estimates, approximately 500,000 servers operate in Google data centers. However, judging by the number of purchased SFP + modules, the company installs approximately 5,000 10GbE ports per month (the servers and the routers themselves).
