Pair of gigabit controllers?

Postby sbohdan » Sat Sep 07, 2013 7:43 am

Why would you need them and how do you connect both? Why is a single controller not enough? I keep seeing motherboard reviews where a pair of these seem to be a must feature for gaming. Why and is there any other application that can employ two controllers?

I assume you mean just two RJ45 plugs on the I/O, my assumption was for failover or in case one dies but I suppose you could set them up half-duplex and use one for receiving and one for outgoing packets, but either way is limited by switch/router, so.... meh. :dunno: I know it's failover for servers anyway :)

I was thinking of this line: "To connect you to the interweb there are a pair of Realtek 8111G Gigabit Ethernet controllers built into the board to get the job done."
Read more at http://www.legitreviews.com/ecs-z87h3-a ... A3rcgmX.99

So why is having two ethernet controllers a key feature?

I think it's more so you can run 2 in a version of NIC RAID (aka Teaming). Realtek has an app to do this but I could never get it to work with my old board.

Hm, The article says it's an essential feature of the MOBO but nobody's sure why :)
Does anyone know for sure?

Simple:

If you want to connect to two different networks
If you want the reduncancy of two network links
If you want link aggregation, ieee 802.xx - this way you could have a 2GBps connection to another network device or client
A seperate network link to your NAS/SAN storage
To run your PC as a gateway/firewall with one link to the internet and the other for your LAN
