FreeBSD is not supported with Dell hardware.
The Dell SAS 6/iR Controller should be a LSI SAS 1068e Controller.
Here are the newest available drivers for the LSI_SAS_1068e Controller
(DELL SAS 6/iR)
There are no drivers for BSD.

Subject: Extremely slow write speeds to disk : FreeBSD 7.1 and Dell SAS
Please can you assist.
I have attempted most of the popular BSD Variants such as NetBSD, Open
The only distrubution that seems to work on the is Dell SAS 6/iR Adapter
is FreeBSD 7.1
Firmware version & date : 9/29/2008 00.25.47.00
But the issue is that writing to disk is extremely slow...i.e. 14Mb per
If I install any other linux distribution, like CentOS, write speek is
the way it should be..it averages around 190Mb+ per second
I was hoping if it were at all possible for you to assist me in with a
later RAID Controller Driver for the SAS 6/iR Adapter
This is on a Dell PowerEdge R300 Server.
BIOS Version 1.3.0
Running Raid 1
