Linux supports many SCSI RAID Controllers.. you just have to have the proper driver module loaded..
What type of SCSI Controller is it ? (manufacturer / Model number)
You may need to make a custom Install iso if you plan to install directly to the SCSI RAID Controller.. I know you are running Suse and I'm sure there is a similar resource out there for you, but just as an example here is a custom .iso to install Debian on a variety of Hardware that has SCSI RAID controllers from various manufacturers..

You could also compile a new kernel for your system then move it from the IDE drive to the SCSI Array. Talk about a great learning opportunity
