HW configuration for 10GbE router/firewall



  • Hi all,

    Have two Dell R420 (8 GB RAM each, regular HDD's in mirror) on hand and two Chelsio T520-LL-CR cards. Want to build HA firewall/router for 10Gbe WAN/LAN. Nothing fancy, no VPN, just plain old block all incoming on WAN and NAT all from LAN to WAN.  :)

    Any special considerations to keep in mind like BIOS settings or maybe some HW incompatibilities you guys can spot from this example? I red somewhere that Chelsio T520 can heat up pretty nicely so maybe to go with some 2U server chassis?

    Any help is much appreciated!

    Cheers!



    • in the BIOS try enable HT support based on the internal CPU

    • enable PowerD (hi adaptive)

    • high up or narrow down both and play with both points together or plain it should be fiddled out in many
      different combinations to get mostly the best effect or benefit from it, as I see it right.
      – high up mbuf size (or narrow down as said above)
      -- change the num.que amount to 1, 2 or 4

    If anything is alright and runs like it should all is mostly fine, but if the amount of mbuf size increases
    once or more often under heavy load or under strong network traffic it could be nice to have more then
    8 GB RAM!!! Don´t get me wrong, but the most users are only watching their machine if all is running
    well and if "something is occurring" they are often not able to do so.

    An additional cooler might be helping on the heating problem well or placing that 1U devices inside of a
    cooled Rack or inside of a cooled server room is the best thing to serve the fans fresh and cool air.

    I can bump up each node to 16 GB DDR3 (4 x 4 GB) and will try the BIOS settings as well.

    For the cooler, I'm not sure I can do much, will test under heavy load in 1U and see how it goes…

    Thank you for the tips!

    At the netgate shop they are also talking about a heating situation that can be going to high in some situations
    and there fore I would really have a look on this!
