Title: Gigabyte GA-P55A-UD3 - Intel RAID Controller
Post by: Iron on September 15, 2010, 06:54:16 am
Hi everybody,

I recently purcahsed a Gigabyte GA-P55A-UD3 motherboard which has an onboard Intel Raid Storage Controller.

Controller info:

The device manager lists it as "Intel(R) ICH8R / ICH9R / ICH10R / DO / 5 Series / 3400 Series SATA RAID Controller".

It has 6 SATA ports and supports up to 3GB/s.

The device works fine, RAIDS are setup through a DOS interface that can be accessed at bootup pressing Ctrl + I. There's also Intel Rapid Storage Technology software which I installed and gives you basic overview over the RAID(s) in Windows.

I am running Windows 7 Ultimate x64.

Since this is my first time dealing with the Intel RAID controller, I have a few questions:

(1.) I currently have a Raid 1 setup on 2 of the 6 controller. I want to expand this to a RAID 10 (using all 6 ports) without losing my data that I have in the Raid 1. Is that possible ?

--> I did not see an option to do that in the DOS config menu...

(2.) If (for whatever reason) the motherboard ever fails and I have to unplug the 6 RAID 10 HD and would connect them to a different motherboard / Sata controller, would I be able to read the data on the disks ?

Or are the disks (once configured as a RAID) only accessible through this specific Intel RAID controller ?


Thanx for your help in advance !

Hi and welcome to the forum.
I can't honestly help you with point 1 as I am not sure if it is possible. However your second point about swapping RAIDs to another controller, this is possible as long as the same controller is used. ie Intel ICH10R

Dark Mantis,

thanx for your answer !

So how can I find out which specific SATA RAID controller I have ?

As I wrote in my original message, the controller was specified with multiple model names...

How do you know it's the ICH10R ? I've read on the i-net that if you don't find the EXACT controller the disks are not readable...

So regarding your answer, what do people do that want to switch to a different controller ? Copy all data ? In my case that would be 6TB... :(

It is the ICH10R on your board(It is actually in the manual ;))
If you wanted to switch to a different controller then I guess that you would have to back up your data first(or image it). For a definitive answer on that maybe Pierre or Peter could help you they know more about RAID than me.

Dark,

thanx. very helpful... I was very confused why the devie manager did not just display ICH10R... ;)

Let's see if Pierre or Peter have some options...

Thanx again !

Yes it is the ICH10R (82801JR) Southbridge on P55A, you can verify that with CPU-z in the Mainboard tab

just to give a heads up for other users:

The Intel RAID Controller on the Gigabyte GA-P55A-UD3 mobo only allows a RAID 10 with a maximum of 4 drives...

very disappointing, and of course that was not stated in the product info, otherwise I would have not bought this mobo...

BE AWARE !

Very true it is in fact stated here:
http://www.intel.com/support/chipsets/imsm/sb/CS-022304.htm

There has been some who have made a RAID 10 with six disks there are some posts about that over  on Intel site, Intel on the other hand listed it as a issue...  

And as I told you over on the Intel site ”A 6 disk RAID 10 is listed as a Known Issue it is not likely supported by Intel to do this even though its a RAID 10 spec.

IMSM 8.9 32-bit shell.exe allows user to setup RAID (1+0)x6 arrays”

Its got nothing to do with the Gigabyte supporting it or not the only reason people could make a RAID 10 with 6 disks was by that Issue in the Intel® Matrix Storage Manager 8.9.
