Option 2: Use add-on hardware RAID card to server such as PERC 6/E SAS controller with RAID or SAS 6I/R SAS controller with RAID. see here for CentOS 5 guide.Īnd if the software RAID breaks, here’s the guide to fix it.

You can now use standard software RAID provided by Linux. Option 1: Disable RAID storage – the S100/S300 controllers by visiting BIOS settings. You cannot use the Dell PowerEdge S100 and S300 PERC RAID controllers under Linux and they are software only RAID (fake RAID device) and it only works with MS-Windows operating systems. How do I use the Dell PowerEdge S100 and S300 Software RAID controllers with Linux operating systems? This was due to code not being released to the public so linux drivers can be written for it or something like that. I rang Dell and they let me know this fact. Installing CentOS, it still saw the 2 physical drives instead of just 1 drive in a RAID 1 array. Booting it said it had 2 SATA 250GB drives in a RAID1 setup. I found this out after buying the Dell T110 server. I didn’t know that Dell’s PERC S100/S300 RAID only worked for windows.
