Based on that info I assume the board having a "8x SAS Ports via LSI 1068E Controller". We received the server with 3 drives + 1 spare as hw RAID-5 preinstalled. During bootup I see that the drives are initialised and everything seems ok.
The issue I am facing is that when trying to install CentOS no hard drives are recognised.
I recently had a problem like that with a Dell box. The trick is that with a hardware controller, it supercedes software RAID. What you need
to do
is go into the firmware controller configuration on boot, before you
get to
grub, and make sure everything's visible and correct. The controller can see the drives, but not present them to the o/s if you don't.
Nope. They may have said they "pre-installed the RAID, but you really need to go into the setup (<ctrl-c>, or -f, or whatever), and see what it presents ->logically<- (key buzzword). If it hasn't been initialized, or put into logical configuration, then it simply will not present the logical drives to the o/s, and AFAIK, it will *not* present the physical drives at all.
I think that it's ctrl-r and that you have to set up "virtual disks" using the "physical disks".
Here are some pics of the RAID configuration:

For me it seems that the drives are initialized and virtual disks setup, so it is not a hardware configuration issue?
I also received confirmation from the vendor that the controller is "LSI 1068E".
Should this controller be supported by CentOS5.5 without a driver disk?
