System requirements depend primarily on the number of IP flows that will be received and processed by the system. The bigger the network traffic volume, the higher the number of IP flows. This reflects strongly on IP flow processing speed and Raw Data file size. The former rises the CPU speed requirement and the latter rises the amount of HDD space needed to store Raw Data.
In addition to this, HDD space requirement rises with the number of Traffic Patterns and subnets you create and with the amount of Raw Data files you decide to store on your system. The number of Traffic Patterns you create also affects the IP flow processing speed.
