The S140 allows the NVMe PCIe SSD 2.5 inch SFF and the NVMe PCIe SSD adapter in a RAID conguration. The NVMe PCIe SSDs

supports volume, RAID 0, RAID 1, and RAID 10.

NOTE: Hot removal or hot insertion of the NVMe PCIe SSDs in UEFI or pre-boot mode is not supported. In the operating system

environment, hot-swapping two or more NVMe PCIe SSDs simultaneously is not supported.

NOTE: Mixing of SATA drives and NVMe PCIe SSDs in a virtual disk is not supported.

NOTE: Ensure that you use only the S140 UEFI conguration utility to congure the NVMe PCIe SSDs during

preboot.

NOTE: In UEFI HII mode, you can use the NVMe PCIe SSD option on the Device Settings page to view NVMe physical disk

properties and perform blink/unlink operations.

NOTE: RAID conguration and boot from NVMe virtual disk is supported only in UEFI boot

mode.

NOTE: RAID conguration using Option ROM (OPROM) is not supported on systems with the NVMe PCIe

SSD.

Physical disk write cache policy for SATA drives

The physical disk write cache policy feature enables the disk to cache the data rst, and then the cached data is written to the storage

device in the background. For more information about managing the physical disk write cache policy, see

Managing the physical disk write

cache policy for SATA drives.

NOTE

: You can use UEFI or Option ROM (OPROM) to congure the physical disk write cache

policy.

NOTE: You cannot congure a physical disk write cache policy on a non-RAID

disk.

NOTE: Linux RAID does not support conguring physical disk write cache policy, or virtual disk write cache

policy.

Linux RAID

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 conguration utility supports conguring 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 conguring Linux RAID, see Conguring 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 S140 UEFI conguration utility to congure Linux RAID feature during pre-

boot.

NOTE: Ensure that the boot virtual disks are congured in RAID 1, using two physical disks of identical drive type (HDD or SSD)

and sector size. However, you can also congure nonboot virtual disks in any of the supported RAID levels in the Linux operating

system.
