![]() If your internal home network is using 192.168.0.X IPs, give the cards something like 10.11.11.11 and 10.11.11.12 IPs. That’s everything you need.įor these sorts of direct connections, simply give each network card an IP address in a subnet different from your home network.

The cheapest possible 10gbe setup is to directly link two hosts. These days, SSDs, multiple-HD arrays, and especially NVMe drives blow way past that limit. Back in the days when most HDs could read/write at a little north of 100MB/s, it wasn’t as noticeable. Ever needed to temporarily move a few terabytes from a computer so you could reformat it? It’s painful. Gigabit isn’t that fast! You’ll see ~100MB/s on network transfers. (If you’re in a “real” office without 10gbit, and you throw a lot of data around to network resources–get it fixed). ![]() For larger environments, it’s certainly going to cost more, but also your IT costs should be a smaller percent relative to human/salary budgets. For small office/home setups, 10-gigabit networking is probably a lot cheaper than you think.
