I am wondering what the recommended bonding modes are for the different types of networks:<br>

For the purposes pf this post, assume mode 4 is not available.<br>
<br>
For Management/Display, I am thinking mode 1 (active-backup) is adequate since there generally isn't a lot of traffic being pushed through.<br>
<br>
Storage, I like mode 0 (round robin) due to some performance results I have seen, though I understand this has to be setup in "custom bonding". Mode 6 seems like it would do well here as well.<br></blockquote><div><br></div><div>As explained above, for NFS, it's not going to help performance-wise.</div><div>Y.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
Guest VM traffic is the one I am not sure about. There could be a lot of traffic going back and forth, so I would want all the interfaces in the bond active to balance the load. Of the supported bonding modes, either 2 or 5 would seem to be the options.<br>
<br>
I am just wondering what others' thoughts and experiences are.<br>
<br>
Thanks! :-)<br>
