Cannot detect RAID virtual drive in Centos 5.5

Hello, we did order a PowerEdge R610 server with RAID 10 disks and we intended to use it as a Centos database server but early in the installation we could tell that the Centos installation program could not detect the underlying virtual RAID disk.
I suppose this is is just a matter of providing the appropriate drivers to the installation program but there is no option whatsoever to add additional drivers so what are we supposed to do?

Junk the cheap hardware-raid and use the md driver and go with software-based RAID. It will probably run much faster anyway.

I like Dell computers so I will not say it cheap hardware. However, I do agree with dlethe in that a software based raid for centos would be a better solution for you.

let me clarify. the hardware is quality. the RAID CONTROLLER is maybe a $2 chip. In this case, you are getting exactly your money's worth :)

Many high end NAS vendors use software md based RAID in their $20K and up gear. they tweak kernel, but it is still pretty much off the shelf md raid

The server is very high end so I sincerely doubt that we are dealing with substandard hardware here.
Since performance is critical I do not think a software solution would be preferable since it as far as I know incurs overhead.

Exactly what controller do you have?
Software RAID is almost always faster than hardware-based RAID.
