The onboard NICs are also on a PCIx bus. You will need to double-check
the system docs and see if they are on a second bus or not.

GOOD IDEA!!  Mirrored RAID 5 (3x2) is a good marriage of reliability and
redundancy. A mirror of stripes (RAID 10) is best for speed but suffers
from instant death if both mirrors loose drive A (or B or C, etc) before
the mirror can rebuild.
