[lustre-discuss] IPoIB best practises

[Laurence Horrocks-Barlow]

The limit of IPoIB is active/backup when using traditional bonding, however I believe you are wanting to multirail your IB. This is achieved buy using multiple LNet's (assuming it uses the same fabric), you should be able to configure for active/active.

This should help with most of the concepts.
