How do I install RedHat 7.2 on Dell PowerEdge 1500 That has RAID Support

["David Chima" <david at sdnp.org.mw>]

We have acquired a Dell PowerEdge 1500 server and want to install 
Redhat
Linux 7.2. 
The server has 3 SCSI disks and we are working on how to install 
these in
a RAID 
format.  

We noted that RedHat detects the RAID format and loads a MegaRaid 
driver
using 
Raid 5 and we think that this means that RedHat can use the hardware 
RAID
on the 
PowerEdge 1500.  

Yet the RedHat 7.2 documentation including the RedHat Custom 
Guide is 
recommending that we install Software Raid first during disk 
partitioning
and then 
create a Raid Device before installation. I would like to find out if we
have to create 
software RAID at all.  

I would like to find out if there is anyone who has some experience with
this. Is the 
MegaRaid driver loaded by anaconda adequate for us to use the discs
without having to 
Make RAID on installation?  

What is the best procedure for installating RAID on 7.2 for our 
scenario? 

Regards,

David
