`<div>Thank you for replay and your effort on napp-it. I really love it!</div><div><br></div><div>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.

<p>The driver is related to the firmware.<br>
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.<br>

<div style=" ; ; ">I
noticed that the r<span t="7" data="151022" style="border-bottom: 1px dashed rgb(204, 204, 204);

support the Dell H330 via mpt_sas driver. So I installed the r<span t="7" data="151022" style="border-bottom: 1px dashed

Dell T630 server with H330 as a VM on ESXi. The H330 was PCI-E
passthrough with 8x 7k2 disks in raid z2.</div>

when I ran the command dmesg | grep sas, it seems that the

<div style=" ; ; ">I
also discovered that the disk performance was worse than the r<span t="7" data="151020" style="border-bottom: 1px dashed
rgb(204, 204, 204); z-index: 1;">151020</span>. To compare,
I ran all the tests via napp-it filebench. For example, for
the fivestreamwrite test, the result of r<span t="7" data="151020" style="border-bottom: 1px dashed rgb(204, 204,
204); z-index: 1;">151020</span> and r<span t="7" data="151014" style="border-bottom: 1px dashed rgb(204, 204,
204); z-index: 1;">151014</span> is around 1100mb/s, but the
r<span t="7" data="151022" style="border-bottom: 1px dashed
rgb(204, 204, 204); z-index: 1;">151022</span> 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.</div>

I miss something in the setup that leads the H330 to run with
