The Linux RAID feature is supported on all the Dell PowerEdge 13th generation systems. You can use Linux RAID to protect data
across multiple devices. For more information about conguring Linux RAID, see Conguring Linux RAID.
NOTE: Ensure that your system has the latest BIOS rmware. You can download the latest BIOS rmware from dell.com/
support.
NOTE: Ensure that you use only the S130 UEFI conguration utility to congure Linux RAID feature during pre-boot.
NOTE: You must ensure that the boot virtual disks are congured in RAID 1, using two physical disks of identical drive
type (HDD and SSD) and sector size. However, you can also congure non-boot virtual disks in any of the supported
RAID levels in the Linux operating system.
