Hi,
We are going to provide a Cinder patch to enable iSER in the next few days, it will allow users 5x faster bandwidth compared to using iSCSI TCP.
The coming OFED 2.0 version (in couple of months) will allow Eth emulation over IPoIB (called eIPoIB). If you want early access to it you can contact me or openstack@xxxxxxxxxxxx.
It will also include SR-IOV support allowing RDMA access and low-latency access from guest VMs.
We are planning  to publish a Mellanox Quantum plug-in soon that will allow simple integration with our InfiniBand and Ethernet hardware (and will have SR-IOV and NIC based IO Virtualization as part of it)  

I hope this helps. In case you need more details, please drop me an email.
BR,
Irena

Subject: Re: [Openstack] How to Solve InfinitBand Adaptor Driver under Ubuntu 12.04?

We're using IB (QDR connectX and connectX2) on our system. It turns out that the drivers included in version 3.2 of the linux kernel are fine. I've built a ppa for updated management tools though; all of those bits are ancient in precise. The ppa is here:

One word of warning; you'll only be able to use IPOIB for connectivity between the hypervisor nodes and the openstack service nodes; getting to VMs requires full ethernet compatibility, which IPOIB doesn't provide. You will be able to use the IPOIB for fast image transfers and really fast volume storage if you have it. Turning on iSER helps a lot with volume bandwidth, but requires a patch to nova compute.
