| SSG software runs on general purpose computers. However, due to deep code optimization and integration with the hardware, the hardware configuration has to meet some specific requirements: | SSG software runs on general-purpose x86 servers that are installed in a 19-inch rack and have redundant AC/DC power and cooling fans. Due to the high degree of code optimization and integration with hardware, there are some special requirements: |

| Server performance is determined based on peak traffic volume value on the channel. When choosing a CPU, RAM, it is necessary to take into account that the calculation is presented for asymmetric traffic. This means that when installing "in-line" for peak incoming traffic of 12 Gbps (Max IN traffic), you need to purchase a SSG-20 license and a platform with parameters: 1 CPU 16 cores and more, RAM 64GB and more. | Server performance is determined based on peak traffic volume value on the channel.
