Hi,
If you're looking at a simple ha bonding setup, why not using active-back= up (mode 1)?
We're using it in almost all our setups and switches toin backup interfac= e in 100ms when a link down is detected (Setting miimon=3D100).
Doesn't aggregate bandwidth but is a very good solution for high availabi= lity whwn you can't configure lacp or a portchannel on switch side.

Hi,
Thanks for the answers.
In this case the only question is: what is better for me? Mode 5 or 6? In which modes how is fast the switching?
Until now I've use 802.3ad lacp on our old cluster. I did some tests and= it was very fast. I know it is not same, but mode 5 or 6 how is safe? Thanks
Regards,
Tibor

Dear members,
I would like to use two switch to make high-availability network conn= ection for my nfs storage. Unfortunately, these switches does not support [ http://802.3.ad/ | 8= 02.3.ad ] lacp, (really I can't stack them) but I've read about mode-alb and mo= de-tlb bonding modes. I know,these modes are available in ovirt, but how is work that? Also= how is safe? Are there for HA or for load balance?
I've read some forums, where does not recommended these modes to use = in ovirt. What is the truths? I would like to use only for storage-traffic, it will be separated fr= om other network traffic. I have two 10Gbe switches and two 10Gbe ports in my = nodes.
Look here: [ https://www.ovirt.org/documentation/admin-guide/chap-Logical_Networks= /#bonds-1 | https://www.ovirt.org/documentation/admin-guide/chap-Logical_Networks/#= bonds-1 ]
"Important: Modes 1, 2, 3, and 4 support both virtual machine (bridged)= and non-virtual machine (bridgeless) network types. Modes 0, 5 and 6 suppor= t non-virtual machine (bridgeless) networks only.=C2=A8
So both tlb (mode 5) or alb (mode 6) are fine only if you use them just= for the storage access but not for VMs.
Thanks in advance,
R
Tibor
