  1. Kyu,

    I spoke with you a bit after the ” Ensure the High Availability and Stability of Oracle RAC: Storage and Network Side Story” talk and was wondering if you happened to have a chance to do any load testing with Orion (or any other tools) to compare performance between dm-multipath, EMC Powerpath, and Veritas? I’d be curious to see if you’re seeing similar results as I am.

    Cheers,
    Steve Bordeleau

    • Hi, Steve,

      It was nice meeting you at the presentatiom. I ran Orion tests before, but not for comparision between
      dm-multipath, EMC Powerpath, and Veritas. Nut I may try some test later when I have a chance.
      I don’t run Veritas.

      thanks
      Kai

      • Hey Kai,

        It was great meeting you as well. I’ve actually found a few anomalies with respect to how the dm-multipath config handles rr_min_io and the path_grouping_policy under the devices section in RHEL 5.4. Luckily, that can all be overridden in the multipath section which is probably not the best solution but it’s a decent work around for the time being. Tuning rr_min_io has proven to be invaluable, especially compared to the paid solutions out there.

        Cheers,
        Steve
