I have a lot of stability issues with IPoIB in EL7. In Windows it’s works flawlessly, but
on Linux is just unstable. So I never had the courage to put an hypervisor Storage network
Are you using Mellanox OFED, or the upstream one?
The iSCSI is only through software? No RDMA involved? Aren’t the CPU being wasted in this
scenario since Connect-X3 does not offload TCP/IP connections?
Finally the IPoIB mode is connected or dataram? Have you tunned the MTU settings?

Hi Vinicius, i'm sorry, I thought I had replied already.
I'm mostly using IPoIB, but gluster is using some over RDMA. I'm using it a few
5 IB nodes, all have dual port ConnectX-3 cards @ 40GB
2 nodes are running windows, one port on each is used for a sync channel for starwind
Vsan to mirror ~20tb of date. The second ports are using for iSCS sharing SMB fiile
shares for other IB nodes.
3 nides are running CentOS 7 and ovirt. One of the ports on each are used for gluster
synchronzaton, gluster is set to use both IPoIB & RDMA. Then the other ports are
using for migratons, iSCSI sharing, and a backup admin channel.

you can see the traffic going through the infiniband and not the ethernet.
