Intel RAID in the X79 chipset

Intel RAID in the X79 chipset

[James Stevens]

Hi

I have an ASUS P9X79 mainboard which has the Intel x79 chipset with a 
built-in RAID controller.

It is detected as 8086:2826 - "lspci" names it correctly.

Getting a Windows drier out of Intel seems a little tricky - the default 
one Intel gives you does not work, ditto the default one from Asus - 
they both have 2822 & 282A, but not 2826.

https://communities.intel.com/thread/37403?start=15&tstart=0

As of "linux-3.15", I also see it is not mentioned in the 
"drivers/ata/ahci.c" file.


When I boot Linux it never seems the RAID volume, but still tells me I 
have three separate hard drives.

I tried a few versions of Ubuntu, including the latest and a few 
versions of the Clonezilla disk duplicator.

According to that Intel thread just adding "2826" into the supported 
list works for Windows - so sounds like it would also for Linux.

I will try it when I have some spare time.

It's got disk controllers - the RAID is a property of the windows driver.

AHCI is a class based driver so it will find the drives

This is correct behaviour. Use the options in your distribution to set up
raid volumes.
