6 Port 2.5 Gigabit PCI-e x4 Ethernet Network Card

I was concerned that the small fan on the card would be loud. I cannot even hear it in my OPNsense firewall situated in my Livingroom.

I have a Dell T630 tower server running ProxMox. The NIC worked with OS native drivers - no custom driver installation was required. All I had to do was edit the /etc/network/interfaces file and now all the interfaces are available for use by guest VMs.

I have the 10gbe M.2 form factor card, disregard all of this if you're considering one of the 2.5gbe cards. This card uses a Marvell/Aquantia ACQ107 chip. Don't expect Windows to have a driver for this. Setting up: Grab the newest driver from Marvell's "Public Driver Downloads" page. (You can just google your way there.) Your search category on the download page is "Marvell Public Drivers" - select your OS of choice and your part number is ACQ107. On Windows, you'll need to unzip the driver into a folder and point Device Manager's driver installer toward that folder manually. After setup, I've been getting intermittent disconnections that I can't seem to resolve. The card hits 10g speed while it's actually working, but it will lose connection for four or five seconds at a time, seemingly at random. [Update: Chip is overheating and shutting down. The short M.2 heatsink isn't enough to keep this thing happy without quite a bit more airflow than my machine has.]

worked GREAT with hardware passthru in a proxmox Ve system , i have been able to vurtualize my 2.5gbit routing

I bought this network card to use in an OPNSense firewall/router machine i was building, I wanted to use one port on the NIC for 2.5gbe WAN and the rest for 2.5gbe LAN. I've been using this for a few days in my firewall and have had 0 problems since install, its been extremely stable. Before installing OPNSense on my machine, I tested the card out on windows and Ubuntu and it seemed to be working fine as well. I'm very satisfied with my purchase, i was reluctant at the lack of reviews but I've had a good experience so far, if anything changes I will update this review.

M.2 10GB NIC, this is exactly what I needed in my homelab. I have a Mini-PC that acts as my Proxmox host, and my NAS holds all my virtual machines. over a standard 1GB connection, the response time on the VM's was pretty awful. The solution: I pulled the NVMe Drive, installed this in its place, and re-loaded the OS on a SATA SSD. Now all my VM's are much more responsive. If the pictures make you think the braded cable is fragile, then you would be right. Handle with care! Only reason this is 4 stars and not 5 is the braded cable makes me nervous and for the price they could have engineered something more robust in my opinion. Otherwise, perfect product.
