It seems it's not possible to have an other hardware raid controller on
this server. But we can use software raid instead. We could have one
20GB raid1 partition for system, and a bigger partition in raid0 for
build data. If we lose a disk during rc/final, we may loose some data,
we can reformat the data partition using only one disk and continue
building isos, until we can replace the disk.
