And remember, you need at least 4 dedicated drives for raid 10.

If the disks are all virgin and not already inside an array, the possible options should come up on the controller. Are you sure you have used the RAID controller's utility tool to remove all raid from your current array?

I was reading somewhere that there is no RAID 10 but its actually RAID 1+0 or Raid 0+1.
is it true, and if its true, does anybody know how can we configure that on DELL Power EDGE 2850?

The PERC4 will do RAID 10 just fine. But for whatever reason it won't "show" it as raid 10 but rather raid 1.
Go into the CTRL M for raid on POST.

CONFIGURE
NEW CONFIGURATION

You'll see all 4 of your hard drives. Highlight the first one. Hit "SPACE" it'll turn it "blinking online"
Highlight the second and do the same.
Once those first 2 show online hit "ENTER," they will change to a "solid online"
Now highlight the 3rd, hit "SPACE" to get the blinking online.
Highlight the 4th and hit "SPACE" again.
Now hit ENTER.
Basically what you are doing is creating 2 RAID 1's at this point.
Now hit F10. This will bring up and show both of your new RAID 1's with a blank space below them.
Hit SPACE on the first one to select SPAN 1. Select SPACE on teh second and select SPAN 2.
This process is tying the 2 RAID 1's into a RAID 10.
Hit F10 again.
This menu shows it as a RAID 1 but this is correct.
Accept.
Good to go.

The Best way to configurre RAID on dell server is to use the DELL Management cd.
it gives you the option to create ant RAID depend upon ur RAID controller and the hard drives you are having.
