Hi all,

Is is possible - in any way - to configure a Win2k Server/Linux RedHat 7.x/8.0 with 2 standard 10/100 NIC's (eg. Intel or 3Com), so the brandwith will become 20/200 (eg. 40/400 in full-duplex), or do I need special NIC's for that. The machine spec are:

MSI Pro266TD Master-RL ATX 2x370 socket / DDR mem / IDE 100 RAID
2 x Intel PIII 733 Mhz Tt orbs.
256 (512 more is soon to come) MB ECC-DDR 2100 mem
4 x 20 GB IBM IDE 100 7200 rpm hdd's (RAID 0+1)
Matrox G400 dualhead
SCSI CD-Rom

you cant configure two nics to load ballance, they dont work that way. the way they do work is one nic for one network and another nic for another network. i guess in theory you could have one proccess use one of the nics for one thing and the other for something else. but it wont double the bandwidth for one device.

As has been said that wont work.

You could get Gbps NIC's, and a switch for them.

Best option is to get some 10/100/1000 NICs.

why, cause the switch is too expensive or something?

I never really looked at it that seriously.

Sorry didn't read your post. I've effectively said the same as you. Giga NICS and switch although expensive, would be the simplest option.

Hey no sweat, I thought you were commenting on what I wrote.

I have sort of non seriously looked into getting Giga, but I never found a switch that I could afford yet. I found some Intel NIC's for like $65 so those aren't too far out of my range.

By non-seriously, do you mean "I have no intention of paying for that!"

Me too! :wink:

Giga lan is a waste of money. PC computes can not even max a switched 100 mbs lan. On a switch you will never get 100% load with PC's.

it has its applications, but for the average joe it will do nothing.

i found some old software that does this for nt4, this guy i work with retired and left me a box of junk he was collecting, in there was some demo software that would take up to 4 nic cards and combine them into one virtual nic at 400mb.

Are you sure that wasn't for 10baseT? So on a hub 1 station ,like a server, could get 4*10(40)mbs. If it was written for nt4 the cost back then of 100baseT cards, hubs and switches would have been very high. It would have been cheaper to use this vs replacing hardware and cables. There are many places that still use 10baseT because they are to cheap to replace the CAT3.

Here's how it works:

Get an Intel or, preferrably, 3Com pair of server NICs. Get a Cisco 2900 series switch, or an HP that also does fast etherchannel. Configure 2( up to 4) prts to be bonded as one. In some cases, the cards themselves may be able to do load balancing without fast etherchannel enabled. This will depend on the switch and specific cards purchased. 3Com server cards do load balancing. I don't recall the exact model #.....
