I've been doing some digging... Seems like ALL Adaptec SATA and SAS RAID (or not RAID) controllers make use of Adaptec's own closed-source drivers.. *sigh* They provide a "SHIM" kit for users to be able to build a driver for their running kernel, but IMHO that sucks bigtime.. Then I need to bust my ass every time there's a kernel update available. I will have to second the votes for using 3ware. Suse has the drivers built into the system for 3ware raid cards. I have used both ide an sata raid cards from them with no problems here at work an home. they work

I'd like to have an option for non-raid cards as well, 4-8 channels, but they seem to be hard to find.. I don't care much if it's a SAS or SATA-II card, and I don't care much about the RAID functionality either since many people say the software RAID in Linux is really good.
Before you totally commit to software raid think about what happens with a drive failure or if you need to boot the SUSE DVD into rescue mode.
I don't actually know the answers, but those are always my concerns with software raid.
ie. For booting software raid does not normally provide any tolerance, and for rescue mode issues I just get nervous.
Basically I don't mind software raid for non-boot drives, but for boot drives I have always avoided it.
FYI: I've been running RAID-1 3ware boot drives for years. The 2-port 3ware card is about $100 IIRC.

Thanks, but this array will be used as storage space only. The system itself with all important system functions and the /home directories are run off SCSI RAID-1 and RAID-5 arrays on LSI Logic SCSI-320 RAID controllers, so that's not an issue here. -- Anders Norrbring Norrbring Consulting
