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
