I’m looking at quad port 2.5Gbe Intel PCIe cards. These cards seem to be mostly x4 physically (usually PCIe gen 3) whilst I have a PCIe Gen4 X1 slot, which is more the theoretical bandwidth that the card can support. The card needs at the most PCIE Gen 3 X2 == PCIE Gen 4 X1 in terms of bandwidth.

How do I fit the card into a PCIe x1 slot? Won’t it lose performance if all the pins are not connected to the physical PCIe connector? Is there a PCIe x1 riser that the community likes that is somewhat affordable?

Thanks

    Yeah a cheap switch probably wouldn’t cut it. You’d need a more expensive managed switch to do segregated vlans, which would balloon the budget.

    Not sure on veth segregation, but you could probably try with equipment you already have (onboard nic w/ veths > unmanaged gbit switch)

    I’ve been looking at the open banana pi router since it has openwrt (debian/Ubuntu too). I think I’m going to wait and hope they put more multi-gig ports on next one tho.
