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

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

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.

Hello,
I am wondering what the recommended bonding modes are for the different
types of networks:
- Management/Display
- Guest VM Traffic
0, 5, 6 are NOT supported over bridges (hence, for guest VM traffic)
- Storage (NFS)
