Summary

We are in need of a faster Gateway. While our current Gateway (a Intel Pentium J4205 has an average passmark of 2442 (918 single) is more than powerful enough for our gigabit connection;

just a single wireguard connection can easily spike the CPU usage to around 70%.


We also want a smaller case (1U) so that we can have more space left in the rack.

Notes

  • an 11th gen Intel i3-1115G4 could easily do wireguard at ~2GB/s so ideally we want to get a system just as powerful or more powerful.
  • one option would be to move wireguard to Erratic instead, however that means that a remote reboot of Erratic will kill all connections.
  • Right now we have an UniFi Dream Machine Pro on loan to test if we like it.
  • CPUs are compared using cpubenchmark.net, cpus should be faster than what we have now.

Options

Bkhd 1U Server Intel Atom Quad Core C3558 6 Lan 2 Sfp + 10G

Comes in a 1U case, can be figured with either a 4-core Intel C3558 (2417 passmark, 852 single) or a 8-core Intel C3758 (4750 passmark, 868 single). Has 6 lan ports and two SFP ports. See also https://www.youtube.com/watch?v=a3EMMYTdOYo

According to the Youtube video it idles around 20w and would spike up to 25w under load. (4-core version)

pros

  • Comes as a 1U case
  • Seems to come with a 12v Meanwell PSU build-in
  • Lots of lan ports
  • Has two SFP ports
  • The 8-core is about twice as fast as our J4205

cons

  • Slower than than our J4205 single core wise.
  • The 4-core version is slower
  • China, so support could be icky (though we are a hackerspace)
  • No video out, only console.
