Software/ Hardware RAID info

[Rick Bragg <lists@xxxxxxxxx>]

Hi,

I am new to setting up RAID arrays, and I have experimented in the past
with software only RAID, but now I have a new Dell PowerEdge 1900 with a
SAS RAID controller daughter card.  

My question is: What is the difference in tools that I will use to
create and manage this hardware array?  Can I still use all the same
techniques and tools such as mdadm, LVM2, and GParted to manage my
array? or is it all in the bios.

Another question is how should I format these disks?  Typically I would
use a root file system, and a swap file system that is twice the size of
my memory.  Since all four of my disks are used for hardware RAID, can I
partition this into 2 array's? one for my root, and the other for
swap...

Any advice into setting this up is greatly appreciated.

Thanks
Rick
