G+_Jason Perry Posted February 21, 2017 Share Posted February 21, 2017 I was just noticing how much 10GbE cards have dropped in price. Few thoughts Is there an affordable way to use them for more than a point to point setup? What upgrades are you thinking of making to your network to maximize performance?

G+_Benjamin Webb Posted February 21, 2017 Share Posted February 21, 2017 Check out Mikrotik Only affordable switches are SFP+ last I checked. Looking at $100 for switch then $59 a card. Probably only worth it if your are doing solid state to solid state drive file transfers. My home build NAS can go a little above gigabit but not enough to justify it.

G+_Andrew Kratochvil Posted February 21, 2017 Share Posted February 21, 2017 I would recommend checking out some of the videos over on Linus Tech Tips, they do a great job going over 10Gb P2P. youtube.com - LinusTechTips Link to comment Share on other sites More sharing options...
G+_Ben Tyger Posted February 21, 2017 Share Posted February 21, 2017 Last I looked the 10Gb NICs were down in a reasonable price. The problem was that any trusted switch was really high priced. Like $150 - 200 USD per port (4 port min). With prices like that, most admins just use them as direct connects between 10Gb NICs. Link to comment Share on other sites More sharing options...
G+_Travis Hershberger Posted February 21, 2017 Share Posted February 21, 2017 Andrew Kratochvil LinusTechTips is great entertainment in what not to do. They do fun stuff, but nothing that 90% of people should be bothering with. IE: Install 10gbe nics in point to point, great. Customize the NIC settings, 90% of the time you'll lower the network performance. Link to comment Share on other sites More sharing options...
G+_Ben Tyger Posted February 21, 2017 Share Posted February 21, 2017 Also, depending on where your equipment is, 10Gb can't run full speed over cat 5e. You may have to run Cat 6(or newer) or fiber. Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted February 21, 2017 Author Share Posted February 21, 2017 I think the only real use cases I have for 10GbE is between switches. Which is the biggest reason why I probably won't bite. Link to comment Share on other sites More sharing options...
G+_Travis Hershberger Posted February 21, 2017 Share Posted February 21, 2017 Jason Perry Yeah, I think NetGear makes a decent 10GbE switch for ~$1500. Also xByte Technologies is selling refurbished network gear now as well, so they might have something reasonable. No 10GbE switch I've seen is making me think it's cheap enough to put in the house yet. Link to comment Share on other sites More sharing options...
G+_Benjamin Webb Posted February 21, 2017 Share Posted February 21, 2017 I would not run ethernet at all and just go fiber due to the run length implementation. Granted you can put 10 GBE transceivers in all these SFP+ cages. Like I said before almost nobody needs this much speed so probably a waste for me. Adapters amazon.com - Amazon.com: Lot Of Two HP 10GB Single Port Mellanox Connectx-2 PCI-E 10GBe Ethernet Network Interface Card 671798-001/666172-001 (Bulk Package): Computers & Accessories $44 for two Transceivers http://www.fs.com/products/11589.html#all_reviews $16/ea Fiber http://www.fs.com/products/17235.html Varies by length Most affordable switches maybe have two SFP+ ports but can point to point to your hearts content as that is a pretty low berrier. Saw a mikrotik with 8 for $3000 lol. Wish whoever tries this luck. Link to comment Share on other sites More sharing options...
G+_Benjamin Webb Posted February 21, 2017 Share Posted February 21, 2017 Found a few 24 port SFP+ LB6Ms Switches on ebay for around $250 should round out your 10 GB network with a bunch of transceiver cards. Link to comment Share on other sites More sharing options...
G+_Ben Tyger Posted February 22, 2017 Share Posted February 22, 2017 Jason Perry also common 10Gb direct connects are between an SAN device like FreeNAS and a hypervisor box like hyper-v, escort (free), kvm, or VirtualBox. Link to comment Share on other sites More sharing options...
G+_Benjamin Webb Posted February 22, 2017 Share Posted February 22, 2017 If you have a freenas box just run it in a jail at native speed. Only virtualize when you have to. I general only use external server for video encoding. Plan to eventually set it up to wake on lan encode then shut down. Link to comment Share on other sites More sharing options...
G+_Ben Tyger Posted February 22, 2017 Share Posted February 22, 2017 Native virtualization on FN is still not that clean. VBox isn't the easiest to setup in FN. Bhypve is still in beta. Link to comment Share on other sites More sharing options...
G+_Benjamin Webb Posted February 22, 2017 Share Posted February 22, 2017 Was saying not to virtualize if you can run in native BSD in a jail. Still don't think you will get enough speed to be worth it with mechanical hard drive anyway. Maybe if everything SSD or M.2. I have an 18TB raidz2 with 6 3TB red drives write speed is about 70 MB/s sustained and read is bottlenecked a bit to about 100 MB/s. Figure at best maybe get like 150MB/s read. This makes sense as main reason for NAS is redundancy not speed. Adding a 10 GB card does not magically give you better performance unless the network is a major bottleneck.

G+_Ben Reese Posted February 22, 2017 Share Posted February 22, 2017 At work I'm running into an issue where all my servers are reporting 10 Gbps, but some appliance in the network is throttling the connection to 1 Gbps. Really, that's typically fast enough; but we started noticing it when backing up large (500+ GB) databases. Even then, the Gigabit network is probably fast enough - just not as fast as SSD on the SAN. I'd like to have 10 Gbps LAN in a home lab for iSCSI - I'm just not sure it's necessary.
