I want to setup redundant infiniband networking. I am going to use servers (Centos 6.4) with dual-port IB adapters (Mellanox Connect-X III series) and two unmanaged IB switches. I know that IB paths are automatically configured by subnet manager, thus inter-switch path redundancy is available "from the box".
My question is: how to get endpoint (server) connection redundancy?
Ethernet connections can be bonded. But I can not find any complete info for infiniband bonding setup.
Is this approach works for Infiniband? How well? Are there any specific restrictions? Are there alternative approaches available?
