I recently built an OPNsense on dedicated hardware.
Hardware:
AMD Ryzen 7 7700
Asus TUF B650m-Plus
64 GB DDR5 ECC (2x Kingston KSM48E40BD8KM-32HM)
Intel i350-T4
Intel x710-DA2
Geekworm PiKVM-A8
300W be quiet! powersupply
Why:
I wanted to test how the Suricata Intrusion prevention performance is. However, even with such a high performance system it is not possible to run ips at 10G. The well known netmap single core theme, where suricata practically only runs in the single core, slows down the performance. Further optimizations are required in this respect.
Total system power consumption:
ca. 42 watt in idle (I have to measure again)
