Is there hardware support for this Motherboard Intel DG965OT Motherboard in FreeBSD 6.2 I have read the Hardware notes but am unable to determine if FreeBSD 6.2 is compatible with Intel DG965OT Motherboard and the on board Martix Storage Technology
I would like to setup a Raid 1

http://www.intel.com/products/motherboard/DG965OT/index.htm

Also are the any concise instruction on how to setup hardware raid 1? I have searched the net

Thanks,
Ivan

This is not hardware RAID controller. For RAID1 operating system does two writes according to configuration stored in Laughable "RAID BIOS"

Basically you get your SATA disks into SATA mode, by disabling RAID in BIOS, and then accomplish same effect in FreeBSD system:

http://www.freebsdwiki.com/index.php/RAID1%2C_Software%2C_How_to_setup

Linux and *BSD explicitly do not support such a "RAID" devaluation, by not supporting such a fake claims that there is some kind of RAID. "Matrix Storage Technology" is Intel's name of Windows driver for their fake RAID controllers.

FreeBSD 6.2 supports following ATA/SATA controllers from Intel:
     Intel:          6300ESB, 31244, PIIX, PIIX3, PIIX4, ESB2, ICH, ICH0,
                     ICH2, ICH3, ICH4, ICH5, ICH6, ICH7, ICH8.

"Download Product Brief" link for your mainboard says it has ICH8 controller.

So it is supported.

Thanks,
This hwlps clear up some things I was thinking of.
I have set up raid 1 with gmirror and I was thinking this would be a better solution.
The only thing is the reporting by gmirror that something has gone wrong.

Could you also please tell me if FreeeBSD has support for the Intel® Server Board S5000VSA, http://www.intel.com/design/servers/boards/s5000VSA/index.htm with a Xeon 5110 processor.
Also is the Intel® Embedded Server RAID Technology II supported.

I have done an extensive search and read the release notes but I am unable to determine if there is support for this motherboard and processor.

Intel say they have Intel® Embedded Server RAID Technology II drivers for Red Hat Enterprise Linux 3.0 and 4.0 and SUSE Linux  Enterprise Server 9.0 SP1 ftp://download.intel.com/support/motherboards/server/sb/d29305004_s5000_server_raid_swg.pdf

I prefer to use FreeBSD,

Thanks,
Ivan

You would like to install "smartmontools" from /usr/ports/sysutils/smartmontools or via
 pkg_add -r smartmontools
to check for disk problems before they hurt you.

then add smartd_enable=YES to /etc/rc.conf to make sure drives start to be monitored at boot.
take time to read "man smartctl" to configure drives for diagnostic self-tests etc.

They hide RAID details in spec sheets

     Controllers supported by the iir driver include:

     o   Intel RAID Controller SRCMR
     o   Intel Server RAID Controller U3-l (SRCU31a)
     o   Intel Server RAID Controller U3-1L (SRCU31La)
     o   Intel Server RAID Controller U3-2 (SRCU32)
     o   All past and future releases of Intel and ICP RAID Controllers.

This looks promising, but take time to browse around their site or even ask in their forums whether that driver is correct, and whether there is support.

ata(4) driver for ATA and SATA supported controllers:

Their 86-page Server platform spec mentions ICH6-like controller on page 26, smae with 180-page spec.
It might be new PCI device ID for ICH9Z or whatever they put in there that requires customizing FreeBSD install CD, but "ICH6-like" claim gives big hope.
