File transfer between 2 computers.

[tekgeek1205]

So I got 2 Windows 10 computers. Computer One has a RAID array, a Gigabit NIC and a USB WIFI NIC. Computer Two has a Tape Drive for backups a Gigabit NIC and a PCIe Wifi NIC. 

 

Both computers use the Wifi for internet and local access.

 

I want to use the Gigabit NIC's as a dedicated line between the 2.

 

When I connect with the wire first and then connect with the wifi for local access/internet everything works. Until I reboot, and then everything is reverted to the wifi connection. 

 

Is there any way to force the mapped network drive to use the direct line.

Hmm, I think I remember reading a guide on like digital ocean about how to do that, something about setting the NICs as a completely separate network or something, I haven't done anything like that in a while though, however it shouldn't reset like that either.

Yeah im having problems finding the right wording for google to send anything useful back. Just how to connect with a crossover.

Like already mentioned, make sure that both nics are on seperate subnets from the Wifi-NICs, but both ethernet nics need to be on the same subnet.

You can set a option called metric for each nic.

You can set it in the window where you can manually set IP adresses. Unfortunately I don't have a english version of windows, but those two screenshots should show you how to set it:

Only do this on your ethernet-nics. You dont need to change anything at your wifi-nics.

Great, i'll giver it a try in about 20 min after a shower. I had begun to give up an was looking at 10gbps NIC's and a switch......way to expensive for a home network. One can dream though.

Let me know how it went. 

10 Gbe isn't terribly expensive, especially if you only want to connect two computers together. If that is your goal, all you need is two 10 Gbe NICs and a cable (depending on your NICs). The setup-process would be the same as above.

The "problem" with 10 Gbe is however, that it actually is faster than normal SATA-SSDs, which means you will need RAID-Arrays/NVMe SSDs or RAMdisks to saturate the connection.

It works if i disable IPv6. Ive tried to set the Interface metric on IPv6 but it didnt work. Do i need IPv6?

 

Ive got a bunch of Roku's, SmartTV's, a Home Group 4 computers, Plex+Sonarr+Jackett server, 6 androids.

I did a quick google search, IPv6 doesnt seam that important unless i wanted easier access for outside my network. I dont ever need remote access. 

 

When it comes to being able to even use 10Gbe, i saturate 1Gbe now, thats why i want a dedicated line. I have a LSI 9261-8i and a 5 disk raid5 I plan to upgrade to 8 next month. I get 450-500MBps between it and a 960 Evo. The HDD's are Hitachi 7K200 RPM 2TB (hua723020ala640). The upgrade is why i want the line, my Tape Drive's backup software is locked to my windows license and hardware.

It depends. If your network is based on IPv6 (which I doubt) then yes, if it is based on IPv4 you can disable it.

In your case you wont saturate the 10Gbe connection then, but it would be a nice bump in speeds anyway. Transfer speeds should be between 400-500Mb/s with your current configuration.

Its up to you to decide if the speed bump is worth the price, which is (if all you need is point-to-point) not all that expensive.

Here on ebay germany you can get bundles with 2 10Gbe NICs + SFP+ direct attach copper cable for as little as 50€.

I would need to go optical i think. I need to go about 25-30 meters. Are the SFP modules interchangeable with any 10gbe SFP nic, Brand and chipset independent?  

[mariushm]

10gbps ethernet is good up to around 55 meters with regular Cat6 ethernet cable, and for up to 100 meters you need Cat6a ethernet cable.

 

New 10gbps ethernet cards are under or around 100$ these days, see Aquantia AQN 107 and AQN 108 (max 5gbps)  based cards for example:

 

99$ : 5gbps max : https://www.arrow.com/en/products/aqn-108-101-sha/aquantia-corp

129$ : 10gbps max : https://www.arrow.com/en/products/aqn-107-104-sha/aquantia-corp

 

The 5gbps cards should give you a consistent 500-550 MB/s (1 gbps is ~ 120 MB/s, so 5 gbps is 600 MB/s maximum but with single file transfers you may not saturate the connection).

 

10gbps cards should give you around 800-900 MB/s  (in theory you get 1.2 GB/s but in real world it's a bit difficult to sustain these high speeds)

The above cards can do 5gbps with regular cat5e cable and 10 gbps with cat6 or cat6a cables. Ethernet cable is cheap enough that you could buy 25m+ factory made patch cords with cat6 or cat6a rating, for example 100' (~ 30.5 meters) lengths :

 

 

cat5e , 21$ : https://www.digikey.com/product-detail/en/tripp-lite/N002-100-BK/TL1458-ND/4438398

cat6 : 28$ : https://www.digikey.com/product-detail/en/tripp-lite/N200-100-BL/TL1490-ND/5971038

 

You should be able to connect the computers directly, between the cards, no need for routers. They'll auto detect the pairs in the cable and recognize the connection.

It may be enough just to set up some different local ip addresses , for example use 192.168.100.1 , 2  for wires and 192.168.0. 11, 12 for wifi (assume 1..9 are left for fixed things like router, printer etc leaving 10..254 for auto ips through dhcp)

 

Then you have things like prioritizing network adapters over others, or forcing connections by using aliases ... and if everything fails you could always set up a ftp server on one of the computer and configure it to only listen on the 5gbps / 10gbps adapter. Since that card won't be connected to a router, any ftp client on the other computer would only be able to connect to it using the 5gbps / 10gbps adapter as that's the only route possible

 

Newegg also has some 10gbps cards but they're more expensive.

There's the Asus 10gbps with SFP+ port at 130$ but you'll probably pay 50$+ for the sfp+ cable as well : https://www.newegg.com/Product/Product.aspx?Item=14U-005F-00043&ignorebbr=1 May as well go for the cards I linked above and use regular ethernet cable.

 

They also have their own Rosewill brand and selling a 199$ with a Tehuti Networks chip : https://www.newegg.com/Product/Product.aspx?Item=N82E16833166130

Should be good but won't be much better than the 100-130$ cards I linked above. Not worth 199$ each.

 

And you'd also find some used 10gbps cards on eBay at reasonable prices, just search for intel x540 on eBay , plenty of single or dual port 10gbps cards for around 100 to 120$ 

Here's an example : http://www.ebay.com/itm/Intel-OEM-X540-T2-10G-PCI-Express-Dual-RJ45-Ports-Ethernet-Network-Adapter-/192132236585?epid=632878946&hash=item2cbbf94529:g:7lgAAOSwwzhZWiij

 

They should be great, but keep in mind you may or may not have drivers for them with Windows 10  and note they need pci-e x8 slots. The cards I linked above only need pci-e x4 which is more common even on cheaper motherboards.

Hey guys, looking at parts today. Can i just buy any SFP+ NIC and any SFP+ module and be compatible with each other? Or are there other things to consider? 

 

I was looking @

also whats the importance of the ratio rating on the fiber? some examples; 9/120, 50/125, 62.5/125,

It's not really a ratio its the core and cladding diameters.

https://en.wikipedia.org/wiki/Multi-mode_optical_fiber#Types

https://en.wikipedia.org/wiki/Single-mode_optical_fiber

 

It's actually more important to check category of the cable, the OM or OS rating. 

 

OM = Multi-mode

OS = Single-mode

 

You'll want to use multi-mode as it's much cheaper, single-mode is designed for extremely long lengths and is rarely used outside of ISP installations or long haul dark fibre.

 

OM3 or OM4 is what you should purchase, anything older is rather out of date and I should hope hard to source anyway.
