Infiniband bonding

Hi everyone,

We have a handful of servers running gluster, equipped with either CX354A or CX456A Infiniband adapters. I am thinking about bonding to fully utilize the two ports each of them has.

However, it looks like mode=1 is the only one working while the network wouldn’t start at all when setting to mode=0. said that mode=1 (active-backup) is the only meaningful bonding policy in IPoIB. Can somebody explain a little bit about it. Why is mode=1 the only meaningful one?

Besides, does that work for RDMA as well?



As InfiniBand works based on LID to LID routing the only supported mode is 1 that is active-backup.

Yes, it works with RDMA.
