Which of these 10Gbps cards would work best in Linux?
I've chosen to upgrade my Linux systems to 10Gbps networking. Caution, even though I've been using Linux for several years on my media server (Mint) and a few other PCs (Antergos, now EndeavourOS), I still feel like a beginner. At the moment, my media server runs Mint but could transition to EndeavourOS in the future, so it should support Debian and Arch. For the 10Gbps switch, I'm considering a Dell PowerConnect 5524. I've compared it with Aruba and others, but it seems that without an account, you can't get the latest firmware updates, which is why I'm leaning toward the Dell option. Now, here are the devices I'm evaluating: Purchase a generic FS-branded model: [link]. Mellanox MCX311A-XCAT CX311A ConnectX-3 EN Intel X520-DA1 It appears I'll have to compile drivers for all of them, regardless of choice, but one of these three seems to work smoothly with Linux? For the DAC cable, does the brand matter or will it function with any of those cards and the Dell switch? (I'm planning to use a Dell-branded one since my switch is Dell.) I should note that I might run into problems with Arch and the Mellanox driver, so should I avoid that card? Also, many people warn about buying fake Intel X520s from eBay or Amazon—could the FS-branded card be safer?
You're considering several options for the network switch. Unixplus offers a 24-port SFP+ + 4x1Gbps Quanta LB6M model for $300, or with an Intel card and DAC cable for around $360, which saves about 30-50%. Arista 7050T provides 48 ports at 10Gbps, but current prices range from $450 to $500 due to recent market changes. You might find a more affordable alternative on eBay, such as Artista 7050 models for roughly $350 or the 7124S 24-port switch for $300. If you prefer a newer option, the Microtik switch with four SFP+ ports is available for $149, though it costs more but reduces network card expenses. Intel x520 cards are also listed at $67, and refurbished Mellanox ConnectX-2 cards are available for $290. Each choice has its trade-offs in cost, performance, and setup complexity.
I believe those Dell switches fit within a budget of under $100 (close to my typical price range for a switch). My system’s maximum write speed is around 300–500MB/s, so 10Gbps should be sufficient. I plan to research Microtik switches next. I’m unfamiliar with Unixplus.com—do you think they’re reliable? Also, any thoughts on Linux compatibility with those cards?
Those Dell switches might be affordable, but remember there are only two 10Gbps ports available (as far as I recall). Unixplus works fine; they also list on eBay with plenty of volume and positive reviews. There’s also a YouTube channel where they demo hardware and clarify topics. I’m not very familiar with network cards. The Intel chip should have strong support, while Mellanox might need extra setup or firmware updates to switch modes, though it should function. Here are several videos about switches I found helpful.
