Hello,
Right now i have an Asus A7N8X-E Deluxe (Rev 1012) with 2 S-ATA disks.
I've setup the RAID 1 in the BIOS, but the raid is not detected under
Mandriva 2006.0.
Have you any recommendations for a new hardware under linux ? One which
is detected and works well?

Don't bother - use the software raid feature (MD) under linux.
The on board stuff is usually half-arsed and I've never been very happy with
any I've tried to use.

I've used these.... they work well:

Since it's a subsystem, there is no driver issues.

They're software raid anyway. The offer no benefit other than setup through
the bios.

Indeed. I specifically bought a motherboad (ASUS P5B) that supposedly did
RAID 1+0 across up to 6 disks (4x320Gb SATA). I should have researched more
because it turns out it's just fake RAID (like a winmodem is a fake modem).
I was a bit annoyed, and use md instead and have no problems with it.

Allistar.

Almost all built in RAID controllers are actually "fake raid". Kind of
a half way between software raid and hardware raid bastard offspring.
If you had true hardware raid, the array would have been seen as a
single drive automatically by Linux. To use fake raid you need to
install a driver, which may or may not be available for Linux. It's
usually a hell of a lot easier to just use the built in software raid
driver of Linux.

I made the same mistake. I bought a rather high end server class
motherboard and wrongly thought it had hardware RAID. I was building a
dual boot system so software raid would have been a real pain in the ass
to implement. This is when I learned about "fake raid". I ended up
giving each OS it's own drive instead of stripping them as I had
originally planned.

I would expect Intel's "matrix-RAID" (RAID on partitions, not on
drives) to help here: Use software RAID for Linux, and hardware/fake
RAID for the other OS. Does anybody have an experience with such a
setup?

You're using software raid on both operating systems and there isn't a chance
in hell that they'll be compatible with each other.

If you want hardware RAID, 3Ware controllers work well and have been
supported in the linux kernel for some time.

I doubt that I get the advantages of pure software RAID on the other
OS if I use the Intel driver.
Or was that a recommendation? If so, is pure software RAID common in
other OSs?

If they have incompatible file systems, then having incompatible RAIDs
does not matter. For data exchange between the OSs one could use a
non-RAID FAT partition.

If the OP is interested in SATA, the LSI MegaRAID cards look good on paper
too.

They will use incompatible data structures, data starting offsets, etc.
If I was dual booting such a system, I'd cough up the 120 bucks and get
a hardware raid controller.

Thx
In fact, with everything written on this thread. We decided to avoid
RAID and use "cp".
