Need help on 10gb Networking or pc to pc networking.

[fakeng]

HI guys, After watching this: 

 

I tried my hand. I was gonna get a crossover cable but then people said it's not needed. Needless to day I got some cheap 10gb sfp+ port NIC cards and a SFP+ cable. I haven't done pc to pc networking in years. Anyways all my shares are going through my default (1Gbps) connection only. And none go through it unless I use ping or Netbios program. At most I get 900Mbits transfer only. 

 

Reading the 6 part web article, "Confessions of a 10 GbE Network Newbie". I realize I can't get it to work. Also they had higher grade cards since they can send out more & their card was a dual 10 GbE card.

 

Anyway here's a screenshot of it working, well sorta. I'm kinda not familar with pc to pc networking and it's been like 8+ years. Also windows 10 workgroup or something can't work with windows 8.1? for some reason that's adding to the mix.

 

 

 

any help is needed and please no hate and *you got boogers/shoulda used linux comments. link or websearch of article: https://goo.gl/r7sYMd

Following the thread for info.

 

Might I ask where you got "Cheap" 10gb NICs? They're all suuuper expensive that I've seen

[fakeng]

They are cheap refrub/used. 10Gb nics. I don't recommended it yet since I can't get 10Gb yet. I got them both for 40 bucks on ebay. The brand is Mellanox ConnectX-2. The brand seems to be already rolling out with ConnectX3 and 4 series already. So think of it as gen 1 or gen 2 10Gbe nics. 

 

The cable was a cheap Cisco SFP+ 10Gbe 5 meter cable for 30 bucks, also on ebay.

 

Think of this as cheap 70 bucks gamble to see if I can do anything better. There's also better cards now that I've seen. You can get the dual 10Gbe nic for 40-90 dollars. You can also get a different type called 40Gbe Nic card using the QDR connect type. The cable about the same price though I can't find longer cables for cheap.

 

I can PM u the links if u want them but seriously, I can't recommend them as of yet since they aren't yet working. ATM it's PC to PC networking and I can only ping to PCs only.

Hopefully you can get some answers. I already have some CAT7 cable, just never found any 10gb networking hardware I could afford. Most switches and NICs I've found are meant for big infrastructures.

Even if I could somehow get PC-to-PC working while having them chat with everything else over the 1GB switch, that'd be neat. Or if I could find an affordable 10GB switch and have them connected to both switches.

You said you could ping between the systems....what do you mean it doesn't work?

[EposVox]

Actually, I had an idea.

If you're able to ping the other machine, are you doing so via a different IP address? If so, create a shared folder on machine 1, and mount it on machine 2 via the 10gbe IP address/share, and see if you can get the speeds that way.

The reason for your issues, is I think Windows is preferring the card with the internet connection and since both are leading to the same device Windows always chooses the first one. What you could do, is setup another subnet specifically for the 10G PTP link. Then Map the drives with new IPs. Hopefully that could fix your issue or break something. Either way worth a try.

Update I kinda got it to work, just gonna redo ip routing or lower IP numbers or something. wifi & 10GbE seems to not conflict as much. 7GB transfer (ramdisk to ramdisk) from pc to pc in 12 seconds.

Hey, that's progress! Awesome. I ended up ordering a couple cards; we'll see if I can work it into my network when I move.

So the computers are able to talk to the rest of the network/internet via the normal LAN, and each other via the 10gbe?

On my PC i had to disable 1Gbps. (still researching on routing and subnet masking.) It's using wifi to connect to my router. The other PC is still connected via gigabit network card. FYI I only get 200-350 MB/s transfer due to raid & SSD limits. In order to get 500+ I had to use ramdisk of course. But yea no more 80-120MB/s gigabit cap. I'm researching teaming and other things too IP tables or routing tables and such. ATM trying software "network bridge".

 

It wasn't that it wasn't able to talk it was using my gigabit over my 10GbE network, cuz it has internet and labbelled by windows 8.1 as "Unidentifed Network".

Alright, so I've been working on this.

A friend linked me this article to help while I play with these connections.

 

So from what I can tell, you're supposed to give the two cards IPs (i.e. 10.201.2.10 & .11) on a separate network in this "/30" range, which when I looked up was subnet 255.255.255.252.

This worked on the first computer, but the second computer says the combination of IP and subnet was invalid.

 

Not sure where to go next

[EposVox]

Alright, I changed the IP addresses and it appears to maybe be working. But only 1 PC can access the other. But I think I've got it working!

if you looking for a 10gbe switch to link 2 pcs together + everything else in you house

i got one about a year ago and havent had problems  it has 2 10gbe + 24 1gbe ports and its passively cooled ad dose not use alot of power

 

and they sell $250 to $300 US on ebay brand new

 

hope it helps
