The insides of a 10G "router"
More recently, a network with 10G seemed only a lot of super-large and rich companies, gradually becoming an increasingly affordable solution. And now we can say that now even relatively small companies can afford to transfer their server infrastructure completely to 10G. What is very important for owners of clusters, and for all those who have tens of gigabytes of data run through the wires in the server rack every second. If you compare the combination of 4 1G ports in each server compared to 10G, then the infrastructure will be head and shoulders more expensive and more complicated than modern 10G solutions. It is especially pleasant that the opportunities for switching 10G-infrastructure are provided by Russian companies.
Typically, such devices are performed in the 1U form factor, and not long ago I was visiting an acquaintance who prepared one of these devices - ETegro Aegis RS200 10G. Actually, about him and talking about:

A simple-looking box hides in itself at least a simple, but at the same time interesting stuffing.
Two power supplies with hot swap function: if one of them fails, the second is capable of taking over the entire electronics inside: the power supply units are installed with double power margin (each) and only 12 volts are output at the output, for this reason they very simple and reliable, and most importantly - less heat and take up less space.
The motherboard is installed on special spacers, the height of which is ~ equal to the height of one network connector, thus providing the best "blowing" air, and the ports themselves are soldered directly to the board, without long legs or extension strips of adapters with cables. Four black radiators hide the “physical level” of the ports, one radiator for each of the four groups of 12 ports.
Under the silver radiator, there is a “fiery heart” - an unblockable switching matrix, providing bandwidth up to an impressive 960 gigabits per second. In order to achieve such traffic values, EACH of 48 ports must be loaded for 10 gigabits in both directions.
The small heatsink on the right is responsible for cooling the processor needed to control and implement L3 functions. There is no marking, but Freescale 8548 is specified in the specification. The manufacturer indicates that it is a SoC specially designed for use in such devices. Let's believe him a word.
Closer to the “end” of the card, a card reader for compact flash cards is installed. The main log is written to this card, and, if necessary, it can be quickly extractedand eaten .
In addition to these elements on the motherboard, a connector with a 512-megabyte RAM module is used (the SO-DIMM notebook format is used), which stores the routing table (up to 129 thousand lines, that is, 2600+ records for each port, if you divide equally) a module with 32 megabytes of flash memory, which stores the image of the system, as well as a handful of solid-state capacitors and other elements responsible for powering all this well-being.
As you can see, all the elements inside are quite simple, and the main work is performed by a single chip, the insides of which are a mystery covered in darkness.
Actually, that's all. As you can see, the device looks very simple, but behind its imaginary simplicity, there are amazing abilities in resolving huge traffic flows.
