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 S160 UEFI configuration utility to configure the NVMe PCIe SSDs during preboot. NOTE: RAID configuration and boot from NVMe virtual disk is supported only in UEFI boot mode. NOTE: RAID configuration 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 first, 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 configure the physical disk write cache policy. NOTE: You cannot configure a physical disk write cache policy on a non-RAID disk. NOTE: Linux RAID does not support configuring physical disk write cache policy, or virtual disk write cache policy. Linux RAID Linux operating systems supported: ● Red Hat Enterprise Linux 8.0 and above ● SUSE Linux Enterprise Server version 15 SP1 and above The Linux RAID feature is supported on all Sirius PowerEdge systems. You can use Linux RAID to protect data across multiple devices. The S160 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 S160 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. Physical Disks 13
