Hi everyone,

I am building a test environment on brand new Proliant ML 330 G6 with 4 hard drives configured on a raid 10.
The current situation is as follows:

I have successfully created the raid 10 using the array controller (also checked it using the HP Tools Media).

Successfully installed ESXi on a USB stick as I was unable to install it on the SAN. All ESXi was able to see was the 4 hard drives despite them being configured as described above.

Also, whilst running the console on my workstation, I was able to connect to machine and yet again saw the 4 hard drives as 4 independent datastores rather than a single logical drive.

If this question has been answered previously please accept my appologies and if possible redirect me to the solution, otherwise if anyone can help it would be great.

Thanks in advance

No problem - some of the "lower end" controllers aren't on the HCL and expect the OS driver to do the bulk of the RAID work. I would bet that is what you have here. In those cases the vendor provides more mainstream OS like Windows or Linux a driver that is needed to get the full RAID capabilities of the device. You can also look at HP's support site and see if they have a VMware specific driver for your particular RAID card. From the symptoms you describe I would probably take an even money bet that this is the case. If so the only solution for fault tolerance is often to upgrade your internal RAID controller.

Good Luck

hi,

From what i understand, your RAID card is actually a re-branded intel ICH10R Raid card, which is a software based RAID card.

ESX does not support software RAID, and the symptoms are exactly as you describe, all the hard drives are presented as individual drives, not a raid set.

Here is a link from the vmware community forum about your raid card:

Yes it is I suspected - you need the OS specific driver in order to enjoy the RAID functionality of that card (software raid). According to the doc (http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01706551/c01706551.pdf) only Windows and Linux drivers are avaialble.

You may want to search the hardware compatibility list (http://www.vmware.com/go/hcl) and find a RAID controller card to add to your system. Also, when searching I would hold out for one that has battery backed write caching, otherwise your write I/O performance will likely be quite unsatisfactory.

Good Luck
