Appendix C RAID Controller Considerations

Disabling the Embedded RAID Controller in the BIOS

Data migration from SW RAID to HW RAID is not supported and could result in data loss. Migrations
Caution
from SW RAID to HW RAID are supported only before there is data on the drives, or the case in which
there are no drives in the server.
If you change from using this embedded controller to a RAID controller card, you must disable the
embedded controller in the server BIOS.
The embedded RAID controller uses different cables than the PCIe card controllers. See
Note
