Nice and fast
Has been running rock solid in a PCIe 3 slot in an old Lenovo box and has been solid and reliable for OPNsense to use without fail. The NIC worked great with the FreeBSD based router OS, so drivers were already good to go. It is very nice to have 2 NICs only taking up one slot and this leaves my x16 slot open for other uses. I was able to test a full 2.5gbe connection/link and had no trouble at all. Great value.

No issues with a proxmox host.
I was just looking for a replacement for my onboard nic. So far no issues. Recognized immediately by a proxmox host.

Modern chips (i226v) in case you're wondering
It came with i226v x 2. Easily recognized by system and proxmox. Great value & so far great card.

Bad. Not a deal.
Purchased because I saw "Intel" and though this would be good. Turns out lots of intel chipsets are added to unsound cards. My symptoms with this one: system crashes when plugged into x1 slot (tried multiple). More stable when placed in CPU x16 slot, but still drops packets. Maxes out at Gen 2 -- total 4 Gbps throughput. Not good, lots of time wasted troubleshooting. Spend a little more and buy something else.

Works great on Opnsense FW - 2nd for unraid
I installed this in my opnsense v17.1.5 firewall and it saw them right away. No need to install any new drivers, and my FW is now upgraded from 1gb to 2.5gb - used one for the fiber modem -which to be fair is only 1gb and one to my network connected to a 2.5gb switch.

Not bad for the price
It worked well when put into a Dell server and didn't have any issues, even though it is not an enterprise-grade chip.

Plug and play for both windows and linux
I got a chance try this on Windows 11 and FreeBSD. Both worked like a charm.

No te compliques. I225-V es el chip que buscas para tu tarjeta de 2.5Gb.
Cuando llevas tiempo en esto de las tarjetas de red, te das cuenta que para 2.5Gb (y en especial para 10Gb), si no te quieres complicar y quieres compatibilidad unánime, eliges una tarjeta que use el chi I225-V (y el X550 para 10Gb) y te olvidas. Funcionan y punto. Si te quieres complicar, verás pronto que hay mil y un chipsets de 2.5Gb y no digo que todos sean malos, solo que en mi experiencia, al final es que no merece la pena. Compra esto y usa tu tiempo para otra cosa.

Po prostu działa
Out of the box działa z ESXi 8. Rozpoznaje go jako dwa nicki i226-V wiec bonusowo wygląda że dają już nowszy chipset. Z mojej strony polecam!

Funziona bene, specs corrette
La scheda funziona bene, la uso da maggio 24/7 per il mio home lab e non da problemi con proxmox 8.4 Anche le specs sono corrette da quanto descritto, probabilmente ne prendero' un altra per un secondo progetto.

Carte réseau performante et stable pour le 2.5 GbE
Ce Dual PCIe 3.1 2.5GBase-T équipé du contrôleur Intel I225-V est un excellent choix pour améliorer les performances réseau d’un PC, d’un serveur ou d’un NAS. La carte offre deux ports RJ45 compatibles avec les débits 2.5G, 1G et 100 Mbps, permettant une connexion rapide et flexible en fonction des besoins du réseau. Le contrôleur Intel I225-V assure une compatibilité optimale avec Windows 10/11, ainsi que les distributions Linux et TrueNAS. L’installation a été simple et rapide : la carte est reconnue immédiatement sous Windows 11 et TrueNAS Scale sans nécessiter de pilotes additionnels. Je l’ai intégrée dans mon NAS sous TrueNAS Scale, où elle fonctionne parfaitement en agrégat de liens (LACP) sur mon switch KeepLiNK 8 Ports 2.5G. Grâce à cette carte, j’ai pu bénéficier d’un débit stable en 2.5 GbE pour le stockage en réseau et les transferts de fichiers lourds. Le format PCIe 3.1 garantit une bande passante suffisante pour exploiter pleinement les deux interfaces 2.5G, et le support Low Profile permet une installation dans des boîtiers compacts. La gestion de l’alimentation est bien optimisée, et la consommation reste faible même en pleine charge. Une carte réseau idéale pour ceux qui souhaitent moderniser leur infrastructure réseau et profiter pleinement du 2.5 GbE, que ce soit pour du NAS, du gaming, du streaming ou un serveur maison.
