A software raid controller? Never heard of such a beast before.
I always thought that there are exactly two ways to do raid,
one way is to have it all hidden in the controller, which makes the
RAID mirror appear as just a single disk to the kernel,
and the other way is to use the kernel software raid (configured with
mdadm).
I've never heard of a software raid controller, where the kernel must
do the work itself. After all, what's the controller's job and
why is it called a RAID controller then?
But I guess we have to use software (i.e. kernel driven, mdadm) raid
then?
regards
Hadmut
