VMWare ESXi 4.0 with Intel ICH7 RAID?

Hi,

We have an ASUS RS120-E4/PA2 server which has an Intel ICH7 RAID controller onboard.


I know this is software RAID, but would like to use it with RAID. The controller itself has an array setup, but the ESXi installer does not see it as 1 device (RAID), but as 2 seperate disks.


Anyone any idea how I can make it so it sees it as a RAID set?

The Server which you are using is officially not listed in the VMware HCL for vSphere 4.0.

That still does not answer my question.
Furthermore, the installer DOES recognize it as an RS120 and gives no further errors.

It's the age old problem with the SATA RAID controllers. I personally gave up trying to get my ESXi machines to see the RAID volume ... :-(

It will only see the two disks as separate because it does not recognize the software raid. It is normal behavior for it to see it as two separate drives.  With ESX 4.0 I believe they have included ICH9 support but not the ICH7 controller

Sorry for the bad news but hope it helps.  I had the same issue with my HP DL320 G5 with ESX 3.5.

The controller it sees. That's not the issue. And it does see 2 seperate disks. That works too.
How do I make them RAID? :(

za_mkh and paulsolov - Can you clarify this point ?

Does Intel ICH7 RAID controller onboard mean Hardware or Software RAID ?

The reason I am having this doubt is generally in Servers at the Hardware level.(for eg HP, we use the ProLiant RAID Controllers to define the RAID Levels such as RAID 5 or RAID 1 before booting into the OS)

Software RAID on the other hand is configured by booting into the OS.

This article states that its a firmware RAID - http://en.wikipedia.org/wiki/Intel_Matrix_RAID

ICH7 onboard raid is not hardware raid, it is a form of software raid on the bios. Many folks call this fakeraid, but it is not a dedicated hardware raid controller that you would normally see in an add-on PCI card

And to confirm what Paulsolov says, it's this distinction that causes ESXi to see the disks as they are and not what the 'fakeraid' is saying they should be ...
