I'm trying to work out this raid card Adaptec 1430SA under OpenSuse. I know it's fake raid, but I'm not to keen on buying a new 3Ware card or a HighPoint (provided they are compatible).
I have tried to compile the binary driver from Adaptec's web site with no success. Furthermore, my installation should take place directly on the RAID array.
What I was wondering is: 1- is it really possible to compile this driver? (has anybody already done it? google told me "not really") 2- is then possible to make a driver disk? (linux dd) 3- Will I have to rebuild the driver for each kernel upgrade? 4- Can someone nice provide me a pre-built driver? ^^
Thanks for the replies as I am a bit desperate on this one!! Also, except nvidia's or Ati's driver compilation, I'm quiet hopeless in kernel building.
Best regards,

Do you "need" the fake-raid to work as opposed to pure software raid?
If not, set the controller up in JBOD mode (just a bunch of disks, no raid functionality)
Then use MDraid (pure software raid) to implement your raid setup.
Pros: -You don't have to find / test a little used fake-raid driver for your card. -MDraid and DMraid (fake-raid) both use the same amount of CPU resources, so no increased cpu load. -If the controller crashes, you can move the drives to any other supported controller because the config data is not proprietary to the controller. You can even split the drives between multiple controllers. Or put a couple off the MB controller, and the rest off of a PCI-express card, etc.
Cons: -The mdraid config data is linux specific, so you won't be able to have a dual boot setup with an alternate OS. (ie. windows).

Thanks for the fast reply. I have been "googleling" for weeks so in a way I know you are right. However, here is my point: 1- I have bought that stupid card because the ICH9R was not supported (the raid fonctions), so even if I did a mistake, I've got the card and the performances are higher than the ICH9R. 2- I didn't manage to build RAID10 using dmraid, and there was something I didn't like in the trick of building a BIOS RAID 1 and using Raid0 in DMraid (which should not work) 3- MDRaid or Dmraid might be lower in terms of performances Why are the drivers provided by Adaptec such pain ? I'm will not have a dual boot because all this is about a NAS server. Am I correct that if I have the driver built for kernel-2.6.XXX-X, I will have to rebuild it again for Kernel-2.6.YYY-Y?
