    Hi
    By the looks it's in kernels >= 3.3 so not in the current releases. You
    would need to build the module. What release of SLES are you talking
    about?

    Hi
    Ahh just checked, it is present in SLED 11 SP3, doesn't look like it's
    present in SLES 11 SP3...

    Hi
    I'm assuming you need it for SLES, I can ask my SUSE Contacts if/why
    not present in SLES?

    Actually I am interested in both the Desktop as well as Server version. That would be certainly helpful. Actually I was surprised to find it in SLED and not SLES, because initially this devices will be more applicable to Server.
    Thanks

    Re: NVMe support

    How difficult is it to build a module for SLES 11 SP3? Can a novice to it? I have a couple nvme devices I would like to try on my power system. gary.geike@hgst.com

    Hi
    This is a ppc system?

    Can you check it's not present?

    Code:
    /sbin/modinfo nvme

    I currently I have RHEL 7.0 loaded on the machine. I was considering moving to SuSE, because i'm having trouble with nvme on RHEL. Then I read this post and saw nvme was not supported on SLES. So really I was just wondering if there were plans to support nvme on SLES. As for your question, my current driver on RHEL is
    modinfo nvme
