Too bad it's not a single SFP+ 10G cage, that would be actually useful then. :/

Would you explain why and how many you would buy? I am sure hardkernel is reading this.

  It would make for a good enough edge/home cluster node. Buy 5 of these, each with two SATA SSDs/HDDs, SFP+ uplink to cheap 10G switch [1], run k8s/k3s, might even be able to squeeze in Ceph. 2.5G switches are expensive and rare. If you want to make use of multiple links to an L2 ToR, you have to set up LACP which is annoying. You could do ECMP for L3 LB instead, but that requires an even more expensive switch.

If I could buy 5-6 of these, with 10G uplink, especially ready to rack, I'd probably order them today.

    10GBASE-T is not very popular and rather expensive, while NBASE-T (2.5/5G) is gaining traction for high speed consumer stuff. SFP+ is cheaper and better, but not exactly common in consumer networks where I imagine most low-cost ARM boards end up.
    - q3k 6y ago
      This is not an ARM board, though. I mean it's no powerhouse, but definitely good enough for cattle in production if you're budget constrained.
      - arghwhat 6y ago
        Yeah, but they offer what provides most utility for their intended target audience first and foremost, and SFP+ would be inconvenient there (especially as copper pluggables ain't free).
- 1MachineElf 6y ago
  10G SFP+ would be more useful IMO too. It's becoming more and more common on switch hardware. Seems to me that anyone remotely interested in 4x2.5Gbps will be using VLANs on a decent switch, so they might as well trunk them on a single 10G SFP+ to make things simpler.

    I think this targets the case where the device itself is the switch/router/main-device/what-have-you not cases the device is hanging off a larger, faster, hardware switch. I see room for both use paradigms though, a 10G adapter would be nifty in addition.

  Not OP, but chiming in: I do many workflows with very large photo and video files. Having an affordable, widely-available single-board-like or single-board-compatible product with a 10Gb SFP+ cage would have a measurable impact on how quickly I can seek assets from my home NAS. Right now the cheapest options are to get a 10Gb PCIe card from Newegg or similar, which'll run you about $200 where I am, and that's just a PCIe extension card.

If you want to go _very_ cheap and dirty you can get some FlexibleLOM/PCIe adapters [1] and some HP FlexibleLOM NICs [2]. This results in a 2x 10G NIC for around ~$15, including the adapter.

      I'm not necessarily going for rock-bottom prices; I wouldn't necessarily trust a $15 2x10G NIC to have good consistency/stability or thermal management, among other concerns. That said I think there's a market for boards between that $15 mark and the $200 I'd have to pay for something considerably higher-end.

        Their original price was probably 500+$. They were for HP server boards originally. Perhaps they recently EOL-ed an entire series.

        $345 list price [1], but yes :) [1] - https://www.cdw.com/product/hp-reman-enet-10gbe-530flr-sfp/3900984 https://www.cdw.com/product/hp-reman-enet-10gbe-530flr-sfp/3...

For typical routing purposes, 10G is overkill. The number of people with faster than 1G internet is extremely small. Business customers who have >1G commercial connections are not in the market for using ODROID boards for their routing needs. 2.5G is perfect for hobbyist use because it is significantly cheaper than anything 10G at the moment, while being faster than common 1G. If you need 10G switching, get a 10G switch.

    The parent board has a generic PCIe slot. You can add whatever card you'd like with appropriate adapters, including a 10G SFP+ card.
    - q3k 6y ago
      If by 'generic PCIe slot' you mean an NVMe slot that I have to buy janky adapters for, and figure out mechanical mounting for, then yeah. But I'm not sure I'd like to depend on that. And then I might as well do that with an Intel NUC, or just go for a normal mini-ITX motherboard.
- stingraycharles 6y ago
  Most of the time 10G routing isn’t for WAN but instead for the LAN.
  - PragmaticPulp 6y ago
    I think everyone is missing the point of this cheap hobbyist board. The PCIe slot on the H2 is PCIe 2.0 x4, which doesn't have enough bandwidth to saturate more than one 10G port. This is why hobby hardware and the enthusiast market is so difficult: You can make a great product at a cheap price point and people will still complain that it doesn't satisfy their high-end niche edge case.

> Too bad it's not a single SFP+ 10G cage, that would be actually useful then. :/ You can plug an M.2 to PCIe adapter and a used eBay 10GbE PCIe cards into the ODROID-H2+. A quick search showed several folks talking about this. eg: https://forum.odroid.com/viewtopic.php?t=39174 https://forum.odroid.com/viewtopic.php?t=39174 . It'd be nicer to have a straight M.2 to SFP+ but oh well.
