Do you know everything about RDMA?

As I mentioned on Twitter (by the way, are you following @rolanddreier?), I’ll be speaking at the Linux Foundation Collaboration Summit in San Francisco on April 7.  My general mandate is to give an introduction to RDMA and InfiniBand on Linux, and to talk about recent developments and what might be coming next in the area.  However, I’d like to make my talk a little less boring than my usual talks, so I’d be curious to hear about specific topics you’d like me to cover.  And if you’re at the summit, stop by and say hello.

    not coding but just using infiniband
    I might have a *somewhat different* set of questions.

    In general I think there’s enough papers, university courses, and talks covering introductions to infiniband, but very little that covers either advanced uses (on the users end) or just gives real-world examples of how your world expands when doing RDMA (for the devs)

    some examples:
    Why and when do you use connected mode, when not?
    Isn’t RDMA ideal for Live migrations in Xen or KVM?
    IF you can spare one minute, pros and cons of partitioning.

    I read about some work to have a unified cache over multiple servers for some applications (GlusterFS), how do you think about that?

    I think it would help if you focus not just on existing users / developers of RDMA but on people who could still add new features to their software using RDMA. i.e. why not do something like the SGA syncing of Oracle in the OSS database world using RDMA, or maybe even memcached could benefit.

    Of course any hint about Pure Storage would also be cool :>

    In any case I hope You’ll have fun giving the talk.
