The first time when I read about it on ServeTheHome I had no idea what this can be used for. Then I saw the price and my jaw dropped, it is cheaper than a basic NIC with dual 25 Gbps ports. Together with the CPU and RAM on it, it makes a lot of sense for specific use cases and the price is appealing: for a Small or Medium Business with some servers and not a lot of dedicated network equipment, it allows to move the router/firewall inside the server case, combining it with the NIC at a good price and without eating up any of the server resources.

Do you want a cheap dual-port NIC at 25Gbps? How about we add some solid router capabilities on it for no extra price?



used Mellanox cx3 (qfsp, 40gbps) cards go for $30 or so on ebay and can go lower (I bought 5 a while back for $75 total).


How long ago was that? I've bought recently newish dual-port (SFP+, 10Gbit) Connect-X 3 Pro at 80 GBP per piece. And that was one of the better prices.


The older QSFP cards go for very cheap here in the US. $20 right now on eBay. SFPs go for more, and even more for the dual interface cards.


this is the cheapest I see right now on ebay for dual port card ($35) so perhaps a bit higher than what I remember from a year ago (I guess silicon shortage effects everything).
