Bonded NICs not working

[Benj Tolli]

Hi Guys,

I’ve been trying to set on the bonding on my NICs but I can’t seem to get a transfer speed over 125MB/s. I’ve followed the guide here: [url]http://fogproject.org/forum/threads/how-to-network-bonding-raid-arrays.40/[/url] but I just can’t seem to get it to work. I’m using Ubuntu 11.10 on a VMWare system.

Please find my ifconfig output here:

I was playing with the same idea of running FOG on a VM and allocate all physical resources to it. It seems like there’s some network slow down in the emulation layer and I couldn’t get more that 250MB/min. Where as on the same physical server if I did a raw Ubuntu 11.10/FOG0.32 install I could get steady 1.6GB/min speeds. I think you’ll find you’ll be much better off on a dedicated server even if it’s not a super beefy machine. I also messed around with Bonding mulitple NICs and got nothing but trouble unless you just want it as a hot backup. There are a lot more errors when trying to load balance and ended up not being worth the trouble.
