I thought HighPoint were all fake RAID? I know for some HighPoint cards the driver is on the install DVD but you have to manually load it, not sure if that's a bug or a feature. You might want to do "modprobe DRIVER_NAME" when you boot the install disc and see if it is there already. You can get an Adaptec 2410SA or 2610SA for about 50 bucks. Nothing to write home in terms of performance, but it's real RAID and it works with openSUSE with no fuss.
I have NO PCI-X bus on my motherboard. It don't have a "real" server. So I must stick to PCe 16x (and less) or PCI 2.2. Maybe the best I can have (Price/Compatibility/Performances) is http://www.adaptec.com/en-US/products/Controllers/Hardware/sas/entry/SAS-240... . But it's 200€...
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")
Anything is possible, after all it is just lines of code.
Sometimes You need skills, and I don't have any in programing.
2- is then possible to make a driver disk? (linux dd)
Why not?
How?
3- Will I have to rebuild the driver for each kernel upgrade?
Yes
Is it worth the effort.
4- Can someone nice provide me a pre-built driver? ^^
You might be able to set that up yourself using the openSUSE build service.
I'll have a look! Thanks for you reply. ############################## Here are the disk stats with bonnie!
