2.5GB Networking

    • New
    • Official Post

    While 10GB NIC's and switches are still a bit pricey for home networking, it appears that 2.5GB is within reason.

    - Has anyone upgraded their network to 2.5GB?

    - How is 2.5GB working out regarding reliability and performance?
    - Do you have any recommendations for NIC's and / or a switch?
    (OR)
    - Would you recommend waiting a bit for 10GB to come down in price?

    Any info or thoughts would be appreciated.

    Has anyone upgraded their network to 2.5GB?

    I bought this switch when I first got my Helios 64. It is linked to my primary switch via 10GB. Switch works very well.


    How is 2.5GB working out regarding reliability and performance?

    When the Helios 2.5GB NIC wasn't segfaulting, it was very good. I blame that on the implementation not the 2.5GB protocol. I've been eyeing up the odroid-h3+ but I might just buy a 2.5GB nic (dual port, intel chipset) for one of my other systems instead.


    Would you recommend waiting a bit for 10GB to come down in price?

    I think 2.5GB is fast enough for most people since their systems can't saturate 10GB. I have nvme to help me do that. 10GB has been around for years and still expensive. I have old Emulex 10GB adapters from ebay that work but use a good amount of energy. I like my switch though.

    That switch is interesting, especially for the number of ports and the price. It seems to have access, distribution and basic QOS capabilities, in the same box.


    Are you using Cat5E or Cat6? While I'm exclusively Cat5E most of my runs are short, less that 40ft. I'm guessing, with short lengths, that Cat5E would work with 2.5GB. Anecdotal accounts say it should.

    I don't get what's going on with 10GB. It's been out for a -l-o-n-g time without price drops that would make it more attractive to home users.

    Have you bought anything 2.5GB or up in the used market? I found -> this nic to be kind of interesting.

    My in-wall wiring is shielded 550MHz Cat6 and up to probably 100 ft long. Cables between my switches and servers in my server closet should all be cat6 patch cables.

    I would agree.

    All of my 10GB adapters are used. My primary server has a Solarflare SFC9020 dual port 10gbe adapter in it now. Using all cheap SFP+ cables
