<p class="MsoNormal">A blueprint around this would be appreciated. I have had similar<br>
thoughts around this myself, that these should be options for the LVM<br>
iSCSI driver rather than different drivers.<br>
<br>
These options also mirror how we can choose between tgt/iet/lio in the<br>
LVM driver today. I've been assuming that RDMA support will be added to<br>
the LIO driver there at some point, and this seems like a nice way to<br>
enable that.<u></u><u></u></p>

I started working on something similar to this that decouples data-path and control-plan for the backend devices and threw some ideas out in Cinder channel this morning. Luckily some folks remembered this post and pointed me to it :)</div>
<div class="gmail_default" style="font-family:'courier new',monospace"><br></div><div class="gmail_default" style="font-family:'courier new',monospace">Wondering did you ever post anything here? Would you be interested in collaborating on this and sharing ideas? I'm planning to have a prototype ready to share later this week, but it sounds like you may already have a lot of this done so it would be cool if we worked together on it.</div>
