Why? Can't I create an active/active bonded interface ?

Ok, so, IPoIB across bonded ports on each host.
Multiple links between switches managed automatically by SM.

Any recent benchmark about IPoIB ?

with dual-port HCA ?

I would like to create a ceph cluster over an infiniband network.
Each server has a signle dual-port HBA.
