    Thank you for replay.

    I've tried googling and searching the mail archive myself. However I didn't find anything related to Dell H330. On the other hand, I think the SAS3008 was supported via mpt_sas long before this release and should not be mentioned in the notes.

    I also tried rebuilding the driver_aliases according to the Solaris document. But it seems that the mpt_sas cannot handle the H330 card. The driver just complains and it simply not load.

    Could you please tell me where should I find the specific patches? Thank you very much.

    Regards,
    Aries

    I'd have to poke at the release notes and relevant patches, but I wonder if it's a matter of updating /etc/driver_aliases to change the binding to mpt_sas for that specific PCI ID?

    Actually the Dell H330 only has one hybrid mode firmware which can be switched between raid and HBA modes. All the distributions include Solaris and linux regard this kind firmware of H330 as IR mode regardless of the raid or HBA mode. Although I always put it in HBA mode, the mr_sas or something similar is used. Therefore when I read the release note of r151022, I was surprised that OmniOS started to support H330 via mpt_sas. However the test result seems a bit disappointing.

    By the way, do you notice any performance decreases in the release r151022?

    The driver is related to the firmware.
           I suppose you are on an IR/Raid firmware. The better one would be       a raidless and often faster IT firmware (mpt_sas). But I cannot       say if its available from Dell or if the one from LSI is working.

                         Hello,

             I           noticed that the r151022 starts to           support the Dell H330 via mpt_sas driver. So I installed the r151022 fresh on my           Dell T630 server with H330 as a VM on ESXi. The H330 was PCI-E           passthrough with 8x 7k2 disks in raid z2.

             However           when I ran the command dmesg | grep sas, it seems that the           mr_sas was used for the H330 adapter which is just as same as           the r151020 and r151014 version.

             I           also discovered that the disk performance was worse than the r151020. To compare,           I ran all the tests via napp-it filebench. For example, for           the fivestreamwrite test, the result of r151020 and r151014 is around 1100mb/s, but the           r151022 only shows           650mb/s. I tried multiple combinations like creating the pool           in one version and import into another version. The issue           seems not related to the creation of the pool but the version           which runs the pool.

             Did           I miss something in the setup that leads the H330 to run with           the wrong driver? Could you please give me some advices? Thank           you in advance.

             Best           regards,
             Aries
