Hello SuSE folkz,
Could somebody please recommend
SATAII PCI / PCI-X Raid controller (4 ports or more) which is
NATIVELY supported in Open SuSE 10.1 or 10.2.
Many thanks in advance,

First, stay away from fake raid. (See http://linux-ata.org/faq-sata-raid.html).
As you can see most Sata Raid controllers are fake raid and thus linux
does not support them except in a JBOD configuration.
For real hardware SATA raid:
I haven't used the 3ware SATA raid controllers, but I have been very
happy with their PATA raid controllers.
They present a SCSI interface at the PCI level, then convert that to
SATA/PATA going to the drive. Their SCSI (PATA) driver has been
supported on SUSE for 3 or 4 years. (Vanilla kernel too for a long
time.) I'm pretty sure their SCSI (SATA) support has been around
equally as long.
The above means you're using the SCSI driver subsystem when you use
3ware cards. Historically the SCSI driver subsystem has been more
stable than the IDE / libata drivers in 2.6. (Rapid improvement in
libata may be changing that.)
FYI: There is another similar card that is also highly recommended,
but I can't think of the manfacturer right now and I've never used it.
