<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="font-family: "lucida Grande", Verdana;">Hello,</div>
<div style="font-family: "lucida Grande", Verdana;"><br>
</div>
<div style="font-family: "lucida Grande", Verdana;">I
noticed that the r<span t="7" data="151022"
style="border-bottom: 1px dashed rgb(204, 204, 204);
z-index: 1; position: static;">151022</span> starts to
support the Dell H330 via mpt_sas driver. So I installed the r<span
t="7" data="151022" style="border-bottom: 1px dashed
rgb(204, 204, 204); z-index: 1;">151022</span> 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.</div>
<div style="font-family: "lucida Grande", Verdana;"><br>
</div>
<div style="font-family: "lucida Grande", Verdana;">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 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> version.</div>
<div style="font-family: "lucida Grande", Verdana;"><br>
</div>
<div style="font-family: "lucida Grande", Verdana;">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>
<div style="font-family: "lucida Grande", Verdana;"><br>
</div>
<div style="font-family: "lucida Grande", Verdana;">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.</div>
<div style="font-family: "lucida Grande", Verdana;"><br>
</div>
<div style="font-family: "lucida Grande", Verdana;">Best
