I've got a Dell PowerEdge 2900 (currently running windows) that I want to convert into a Linux server. But, it's got a hardware RAID controller and I want to be sure I don't destroy the configuration utility. When it boots, I can currently (when prompted) hit CTRL-R and it launches a raid config utility:

PERC 5/i Integrated BIOS Configuration Utility 1.02-0007

Where is this utility located (Disk vs BIOS)? If it's on disk, what's the best way to keep that functionality available post-linux install?

Does this RAID card have battery backup? If not, you're better using software RAID... – Javier Nov 10 '12 at 17:56

The pre-boot RAID BIOS is embedded into the RAID card. It's completely OS-independent.

Great; thanks for the swift response. It sounds almost silly to ask that question since it says "BIOS" in the name, but I seem to remember being bitten once by a raid config utility living on the disk once, and once it's gone, it'd be painful to get back. – Gus Nov 10 '12 at 18:11
@Gus the RAID-controller needs to map into BIOS so you can boot from a raid-device. Apart from that the configuration is stored in NVRAM of the controller AND in every disk. – Nils Dec 30 '12 at 22:25
