Just curious :)
Using IANS I have exactly that I have one in full duplex for receiving and one full duplex for sending. In theory I should be getting what you mention, 200mps each way, but I since each line is send and receive I should have 200mps send, and 200mps receive, for a total of 400mps. IANS also works with gigabit cards as well. In fact I remember reading or discussing with an Intel support guy that IANS can be used with other ethernet cards as long as one in each group is an Intel card. > [further stuff about e100 & IANS] > > Thanks for that _very_ comprehansive help - I'll have a look at that lot :^) No problem, I thought I would include some actual things you could use instead of just a recommendation. If you are using Intel cards, which I highly recommend, then IANS is a must, if you are wanting to use more than one interface in a machine as a single interface. > However, I'm looking to use a dual gig card (something like a SysKonnect > SK-9844), with the ports bonded, and then running vlans over the resulting > bonded channel. Your original post did not mention that. You mentioned a dual Intel nic. Either way if you have one Intel nic you may still be able to achieve what you want. IANS does support gigabit but all cards in the group must be the same speed. No mixing 100's with 10's or 1000's. All 100's all 10's or all 1000's. I would stick to Intel nic's. They have yet to let me down, and you can get them retail or dirt cheap used on Ebay. Like $10 for a Pro 100 adapter (the mini ones), and gig and dual cards for between $50-$100. You should be able to use vlans with IANS. Read the read me. > http://www.syskonnect.com/syskonnect/products/b0101_ethernet_9844.html I will have to look into this. But I am an Intel nic guy.

Correct me if I am wrong, but ifenslave is a tool from the Beowulf project. I remember downloading it and trying to get it to work in my RaQ XTR. But I could not. All the info was duplicated, IP, subnet, etc. All looked good from ifconfig, but did not work like IANS, or at all. Only one interface was working. The Cobalt uses a weird chipset ethernet cards that are built into the motherboard. They use the dp83815 driver, and I believe that is the chipset as well. Either way I played around with ifenslave and did not have any luck. I am not sure if you have to have the bonding driver compiled or loaded in your kernel. I would imagine that might have been my problem. But I am not going to attempt to replace the Cobalt kernel. I will eventually be phasing the machine out for one I can upgrade. :) That machine will have Intel nics or a gigabit Intel nic so it won't be a problem. > Anyway (hopefully not pushing my luck too much here :) anyone used the > syskonnect with some kind of channel bonding/aggregation and vlans? No, may be with the card you want to use. But otherwise it should be something that can be done. Like I said I am doing it and have for a while with a dual nic card in one machine, and two ethernet cards in another. Both are basically the same when all is said and done. Reading and writing from those machines is faster than using just a single line, so something is able to aggregate the bandwidth. Not sure if it's a full 400mps but definitely over 200mps (single card full duplex). -- Sincerely, William L.
