Due to the nature of packet analysis and granular drill-down reporting features, Sensei require more horsepower than a standard L3-L4 firewall.
Sensei requires at least 4 GB of memory. Installer will not continue if you have less than 4 GB of RAM
A roadmap feature - Cloud reporting - will enable you to install Sensei to devices which have limited amount of memory. E.g. you'll be able to install Sensei to a Raspberry Pi.
CPU & Memory
Because the analytics module relies on Elastic Search to do Big Data processing, amount of the memory available in the system is crucial for the performance of the whole product.
At least dual-core (i5 and equivalent) or preferably quad-core modern CPU (i7 and equivalent) would be advisable.
