DUAL Gigabyte Ethernet "Simultaneous"?

[inveterate]

I've got DFI LANPARTY UT ULTRA_D,, It'z got Dual gigabyte Ethernet, does that mean i can connect 2 wires and use them simultaneously??????

With dual network cards you can connect 2 separate network cables at once to two separate networks, or the same network. Typically this is used to route traffic/share an internet connection on a desktop PC. Note you most likely cannot use 2 internet connections at once efficiently, and DFI probably doesn't provide any software to team the two connections together. You also have to have a switch that supports that 802.1whatever feature for that to work.

Gaidin is correct. You will be able to connect each port individually to whatever you wish. Unless, however, you are running some pretty serious software(read; very much not XP Home and not XP Pro) and a rather nice switch(trunking aware) you can forget about bonding the connections together for higher capacity. Luckily, this almost certainly doesn't matter at all to you. You would need a full speed OC-48 line to your house in order to saturate a dual gigabit link. As for things like network attached storage, if you have disk arrays that can touch 2gb/s for more than a moment, you already have fibre channel. It is certainly no bad thing; but dual GBe is pretty excessive for most home uses.

IC, Thx, Y they bother put this in .. Jezzuz

I've seen a ton of new motherboards that come with Dual Gig network ports and never really understood what the point of that was...

Dual gigeth mobo's is to easily setup dedicated firewalls

Actually you CAN get a 2Gig LAN uplink with those 2, but you'll need a mighty expensive pro-switch to do it, and the gain is really not that great unless you transfer close to terabytes of data over say 4 bundled links..

When they say Gigabyte LAN, Do they really mean 1Gigabyte per second, or minute

 

[freebsdrules]

They mean Gigabit per second (gigabyte/8 per second)

The main point of having dual network cards is for reliability/non-stop service. NOT for performance. Sure you can bond them for performance reasons but it isn't the main goal.

You connect one nic to one switch and the other to another. One can design a network where taking down a switch that holds anywhere from 96-380 ports won't disrupt communication or "the network".

The only way to do that is to have dual-attached servers - one NIC is primary where the other one is secondary. I've tested this many times and we're talking sub second failovers. Good stuff.

In the lab a 4 layer network experienced sub-second re-convergence of all services (voice/video/data). Meaning you can upgrade a switch or lose it and there is literally no impact to service.
