Dell PowerEdge RAID Controller S140 User’s Guide

Linux RAID

Linux operating systems supported:

  • Red Hat Enterprise Linux 8.0 and above
  • SUSE Linux Enterprise Server version 12 SP2 and above
The Linux RAID feature is supported on all PowerEdge 14th generation systems. You can use Linux RAID to protect data across multiple devices. The S140 configuration utility supports configuring RAID 1 virtual disk in UEFI mode. The Linux operating system can be installed on that virtual disk, and once the system boots to the Linux environment, the Linux native RAID driver manages the virtual disk. For information about configuring Linux RAID, see Configuring Linux RAID.
NOTE:Ensure that your system has the latest BIOS firmware. You can download the latest BIOS firmware from https://www.dell.com/support.
NOTE: Ensure that you use only the S140 UEFI configuration utility to configure Linux RAID feature during pre-boot.
NOTE: Ensure that the boot virtual disks are configured in RAID 1, using two physical disks of identical drive type (HDD or SSD) and sector size. However, you can also configure nonboot virtual disks in any of the supported RAID levels in the Linux operating system.
