July 20, 20169 yr Author Just wondering if this is feasible, or if we are still limited to single-NIC speeds between unraid and windows? You only see the improvement if you have more than 1 box accessing unRAID at the same time. If you have just 1 Windows box accessing unRAID, it will only get single-NIC speed. If you have 2 Windows boxes accessing unRAID at the same time, each one can theoretically get close to full single-NIC speed.
July 21, 20169 yr Damn Where is this limitation being caused? The VMs each believe they have 10GBit, even though the host itself will be connected to the switch via 4GBit LACP. Would this maybe "trick" it? I basically have a Downloads virtual machine, this has a virtual 10GBit NIC. I want to be able to copy to the UnRAID box from that VM at better than single-NIC speeds.
July 21, 20169 yr Author Would this maybe "trick" it? No. Windows doesn't do balance-rr mode bonding. Read the entire thread.

July 26, 20169 yr Cheers Johnnie, will watch with interest Wish 10GBit switches were cheaper, saves the whole hassle!
July 27, 20169 yr Author If you only need one workstation with 10GbE performance, you can use 10GbE NICS and a crossover cable between your workstation and unRAID.
July 27, 20169 yr If you only need one workstation with 10GbE performance, you can use 10GbE NICS and a crossover cable between your workstation and unRAID. Pardon me for not googling, but do you really need a special cable for crossover? I thought all the specs after 1GB included auto mdi-x. Or is it dependent on the specific physical media, i.e. optical vs copper?
July 27, 20169 yr If you only need one workstation with 10GbE performance, you can use 10GbE NICS and a crossover cable between your workstation and unRAID. Agree, although smb multichannel works reasonably well on windows, 10GbE is much better. Pardon me for not googling, but do you really need a special cable for crossover? I thought all the specs after 1GB included auto mdi-x. Or is it dependent on the specific physical media, i.e. optical vs copper? I'm using Twinax Direct Attach cables, usually passive up to 5meters and active up to 10 meters, like these: http://www.ebay.com/itm/SFP-10G-30AWG-Passive-Direct-Attach-Cable-DAC-Twinax-Cable-3-Meter-/172233602165?hash=item2819ec3475:g:v~sAAOSwGotWjuoi Some 10GbE NICs, like the Mellanox Conmect-X 2 can be bought for less than 20$, you can also use more than one on the same computer, I have two of these on my desktop, each connected to one of my fastest unRAID servers, all the other servers use gigabit, you can also by a dual port 10GbE NIC but if you have slots available it's cheaper to buy 2 single port NICs.

Or is it dependent on the specific physical media, i.e. optical vs copper? The Intel X540-AT2 (copper Cat 6a) will automatically do crossover for you (auto MDI-X), so you can use a regular straight-through cable to go back-to-back without a switch.
