0, 5, 6 are NOT supported over bridges (hence, for guest VM traffic)

Unless you have multiple mounts (multiple NFS storage domains) you are
unlikely to get a bandwidth improvements, only HA from bond for NFS (in
that sense, it's better to use iSCSI in such a scenario)

As explained above, for NFS, it's not going to help performance-wise.

Generally, avoid mode 0 - Round Robin or you will face problems sooner
or later. RR will generate TCP out of Order.

Go for mode 4 / lacp wherever possible

[ovirt-users] Recommended bonding modes?

[Alan Murrell]

Hello,

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


  - Management/Display
  - Guest VM Traffic
  - Storage (NFS)

For the purposes pf this post, assume mode 4 is not available.

For Management/Display, I am thinking mode 1 (active-backup) is  
adequate since there generally isn't a lot of traffic being pushed  
through.


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.


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.


I am just wondering what others' thoughts and experiences are.

Thanks! :-)

Regards,

Alan
