Right now I have SAP DB running along with a webserver on two hardware
mirrored SCSI disks and the performance is ok, but I would like to know
what the database would be happiest with in terms of disk setup, for
when the time comes to tune the setup for speed.

The box is running Linux on a dual P3 with 1 GB of RAM.

Naturally all disks ought to be mirrored and the filesystem, data and
log ought to be on seperate disks, this means a minimum config of 6
disks:

Files: 1 + 1
data : 1 + 1
log  : 1 + 1

For the filesystem mirror I think the dedicated SCSI RAID controller
will do nicely.

Now, the question is: Who is better at doing the data and log mirroring,
the hardware (or OS) or sapdb?
