I'd really love it if the 10GbE cards would drop under $13 :) And especially the switches to become cheap.
It really feels like we've had 1GbE like forever (it was already standard on my 2004 PowerBook!!). But 10GbE is still hardly affordable.
- musicale 6y agoExactly this. Few laptops have 10GbE, though many have Thunderbolt and USB 3.1.
- mjevans 6y agoI hope all the patents expire soon and that good products at good prices follow quickly. The standard was released in 2006, but I'm not sure how close to that release date the last relevant patent involved was issued. https://en.wikipedia.org/wiki/10_Gigabit_Ethernet#10GBASE-T https://en.wikipedia.org/wiki/10_Gigabit_Ethernet#10GBASE-T "10GBASE-T, or IEEE 802.3an-2006, is a standard released in 2006 to provide 10 Gbit/s connections over unshielded or shielded twisted pair cables, over distances up to 100 metres (330 ft)."
- willis936 6y agoWhat is pantented about implementations? I’m surprised that the nature of the implementation of a public specification is patentable. I spent a few years implementing 802.3 physical layer testing. At the conferences it was clear that things were written carefully to not cover implementation, but they went so far in the necessary details that there were only a handful of reasonably performant and economical solutions.
- msbarnett 6y ago> I’m surprised that the nature of the implementation of a public specification is patentable. Prepare to be very surprised, I guess? It’s pretty routinely done, eg) look at any of the MPEG standards. I don’t know what patents, if any, cover 10GigE, but in general IEEE, which governs that standard, will accept Essential Patent Claims in a standard provided the Patent Holder will provide a Letter of Assurance indicating that they will license said patents under FRAND (fair, reasonable, and non-discriminatory) terms – which does not mean free.
- GekkePrutser 6y agoYeah I don't think patents will play a major role in the price. WiFi would be a lot more patent-encumbered with technologies like MIMO. Yet it doesn't seem to preclude cheap commodity hardware. My Unifi WiFi 6 AP was only a bit more expensive than the AC one.
- wl 6y ago10GBASE-T is unreasonably power hungry. SFP+ passive cables are far superior for short lengths and fiber optics are superior for anything longer. I've got two SFP+ 10GBASE-T transceivers on my home network and they seem to sit around 80°C all the time.
- m463 6y agoWhat kind of things will use more than 1gb? And can most systems push this kind of data? (home systems)
- ianlevesque 6y agoA basic NAS with a handful of spinning rust drives can easily exceed 1 gigabit/s. A single SSD can as well.
- PragmaticPulp 6y agoA single modern mechanical HDD has more sequential throughput than a gigabit ethernet link. SSDs are an order of magnitude faster than gigabit ethernet. Google fiber is rolling out 2Gbps internet in many locations 1 Gigabit is definitely good enough for most general use cases, but once you start moving files around regularly it becomes a huge bottleneck.
- rodgerd 6y agoA single modern HDD can push out (sequential) 100-200 MBytes/s per spindle. Commodity SSDs can saturate a SATA port. So yes, it's trivial to saturate a 10 Gbit/s link, assuming that the kernel and userland can keep up with the hardware.
- rektide 6y ago2Gbit internet service is becoming semi-common. Wifi 6E can do almost wigig/uwb speeds, near 7Gbit hypothetical. A single modern NVMe drive does 56Gbit. USB4 can do 40Gbit. It can connect direct computer to computer.
- GekkePrutser 6y agoMy systems definitely can. But indeed as others have said, even broadband connections are exceeding this speed now. USB exceeds it by a factor 40 and is on cheap laptops. Yet Ethernet remains so expensive.
- CyberDildonics 6y agoEven the raspberry pi 4 with USB 3 on a single PCIe 2 lane has a limit of 4gbs.
- tguvot 6y agoWhat about Mellanox ConnectX-3 for ~30 ? More than 13, but less than 1300
- floatboth 6y agoPlus Intel X520 goes for a similar price, I think older Chelsio cards too
- tguvot 6y agoYeap. Mellanox has one advantage , even though it pcie x8, if you put it to pcie x4 slot, it works nicely (according to specs it downgrades itself). Intel - not that sure about it
- floatboth 6y agoIt definitely does, in my PC right now. Why wouldn't it? Not downgrading would probably be an egregious violation of PCIe specs. PCIe is built to work no matter the restrictions. You can connect an x16 gen4 GPU via an adapter to an x1 gen2 miniPCIe slot and it will work.
- tguvot 6y agoWhen I was shopping for one a few months ago, it wasn't explicitly mentioned it X520 specs but mentioned in Mellanox specs. I know that in the theory it supposed to downgrade itself, but implementations may vary depends on fantasy of designers. At the end, I just got motherboard with few 10GbE and SPF+ on it.
- oso2k 6y agoYou can pick up used HP NC523SFP or NC552SFP (better!) NICs for about $15-$25 each off eBay. The drivers fell out of support on RHEL8/CentOS8 but I think Fedora Server, RHEL7/CentOS7 and Ubuntu Server are fine with them. TrueNAS can make use of them as well. Then all you need is a 10GbE switch that can do bonding. Or, just make yourself a router with a bunch of dual port NICs. https://www.ebay.com/itm/LOT-OF-2-593717-B21-HPE-NC523SFP-DUAL-PORT-10Gb-SERVER-ADAPTER-LP-BRACKET/264525482952 https://www.ebay.com/itm/LOT-OF-2-593717-B21-HPE-NC523SFP-DU...
