Hardware SCSI RAID 1 controllers

Hardware SCSI RAID 1 controllers

May I please have some opinions of the best controller card to work a
SCSI RAID 1 solution driving a pair of Seagate 9.1GB 10,000 rpm drives
on a PIII550 running RedHat 5.2 (to be upgraded to 6.1)?

1. Mounting a RAID-0 partition on an IDE-SCSI/RAID Promise Lite controller

I am having some troubles trying to configure my RAID-0 system in Linux
(Red Hat 7.2 kernel 2.4.18).  My controller is the Promise FastTrak lite
and it is on my motherboard.  I am booting using lilo, and i can get it to
load and recognize my drives just not the RAID stripe.  I use two 60G
drives to make a 120G RAID stripe.  There are two NTFS partitions on the
stripe, both for Windows XP.

My question is what do I need to do to be able to mount these two NTFS
partitions under linux?  I don't know which device I am supposed to use.  
The drives are seen as /dev/hde and /dev/hdg, since they are on what I
think is referred to as IDE-SCSI.  How would I go about telling linux that
these two drives are really a RAID setup?  I have compiled RAID and SCSI
support into the kernel.

My lilo.conf seems to be okay.  It goes something like this:
  bios=0x80      #My root linux device, on IDE0 slave

append="hdb=973,128,63 hde=7476,255,63 hdg=none"

Is this part correct?  Is there something I am leaving out?  The drives are
all recognized okay, but I still can't mount the NTFS partitions.  What
device should I be using for the mount?  I don't think it really matters
that they are NTFS formatted, all I need is to be able to access both
drives as a unit.

Here is what my fstab looks like:

/dev/hde1   /mnt/winxp   ntfs  ro, umask=0 0 0
/dev/hde5   /mnt/media   ntfs  ro, umask=0 0 0

These settings worked before I switched to RAID so I assume they are the
same except for the device I am mounting.

Thank you,
