Dual Lan

I'm not sure if this belongs here or in the motherboard section, but I'll start here. Motherboards with dual lan connections used to be hot a while back because, at least with nvidia chipsets, there was a pairing or teaming feature that was supposed to take advantage of the two pipes to increase the bandwidth coming from the router. Now whether my 10 gig dsl service and modem can actually supply enough to make a difference is certainly a factor, but when I see dual lan mobos they don't seem to talk about the teaming feature anymore. Many of the higher end boards only use a single connection. Does anyone have any knowledge or thoughts on this subject when considering the latest z97 generation mobos? thanks zz03
 
Marketing gimmick from that era. I wouldn't base my decision for a motherboard on whether or not it has dual lan.

If you're going to use Gigabit LAN, then it will be a full duplex connection. Transmit and receives happen at the same time, so the effective speed is considered 2 Gbps.

Teaming nic's requires the hardware on the other end of the cables (a switch that supports it), the right NIC firmware, and software to run it. Not typically something you'll use at home.

thank you, and of course I misspoke its 10 mps not 10 gps internet. so redundancy is the only upside I can expect. Or is that even the case? same controller might well kill both at same time...

No. Teaming allows you to aggregate the adapters to provide higher aggregate bandwidth. Generally server applications. In addition with two NICs you can connect to two seperate networks. Or you can run the board as a router with a pair of NICs.

Or with Windows 8/8.1 connecting to another 8/8.1 (or server 2013) a feature to those OS called SMB Multichannel will band together the NICs for higher bandwidth, and it isn't just aggregate bandwidth, it is discrete bandwidth.

By that I mean with two NICs and teaming, you have 2x1Gbps of bandwidth. Up to two connections, each with 1Gbps available, but the maximum single connection speed is 1Gbps. With SMB Multichannel it actually gives you 2Gbps of bandwidth for those two NICs, so you can have a single connection at 2Gbps, or multiple connections up to 2Gbps.

SMB Multichannel will do redundancy just like link aggregation will. There are now very limited cases where link aggregation is better than SMB Multichannel (but there are a few). On the whole SMB Multichannel is better, but is ONLY supported in Windows 8/8.1 and server 2013 (and I assume it will be in future Windows implementations).

I am utilizing it with my server and desktop to get 235MB/sec file transfers between then with a pair of Intel NICs in each machine.

I think you're misintepreting what I said. Not exactly sure what you're saying "no" to, but whatever.

Teaming is what you are going on about, not what I was bringing up other than to say you don't typically see it at home, and motherboards sold to PC builders aren't being sold with Dual LAN for teaming.

Thanks for sharing.
 
Thanks to both for sharing! You guys have taken it over my head at this point but I hope the thread continues that I may continue to learn.

No to marketing gimick. There are plenty of uses for dual NICs on a motherboard even if they don't have the software the supports NIC Teaming (though server 2013 has native support, not requiring driver support, so non-Intel NICs can use teaming).

In terms of PC's like we're discussing, it's a marketing gimmick.
 
You mean other then SANS, NAS or Firewall, Don't see any.
Would teaming also rely on the LAN network connected via switch, The sources (if also teaming) or transfer of two or more at once and you are using a SSD?

For internetz no use until ISP support 2Gbps or more (drool).
 
I use the dual nics in my media server. I have my 2 HDHomeRuns on a separate subnet so their traffic is isolated. Necessary? Probably not.
