Page 11: Physical Disks
Physical Disks NOTE: The physical disks in a virtual disk must be of the same drive type (HDD, SSD or NVMe PCIe SSD). For example, you cannot mix an HDD and an NVMe PCIe SSD in the same virtual disk. Physical disk features Physical disk roaming Physical disk roaming is moving the physical disks from one cable connection or backplane slot to another on the same controller. -
Page 12: Mirror Rebuilding
Mirror rebuilding A RAID mirror configuration can be rebuilt after a new physical disk is inserted and the physical disk is designated as a hot spare. NOTE: The system does not have to be rebooted. Fault tolerance The following fault tolerance features are available with the PERC S140: •... -
Page 13: Physical Disk Write Cache Policy For Sata Drives
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 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. -
Page 14: Virtual Disks
Virtual Disks A logical grouping of physical disks attached to a PERC S140 allows you to create multiple virtual disks of the same RAID levels, without exceeding a maximum of 16 virtual disks. The PERC S140 controller allows: • Creating virtual disks of different RAID levels on a S140 controller. NOTE: Ensure that you do not mix RAID levels on the same physical disks. -
Page 15: Disk Initialization
The CC operation reports data inconsistencies through an event notification. A CC cannot be user-initiated in the BIOS Configuration Utility (Ctrl+R). However, CC can be initiated using OpenManage Server Administrator Storage Management. For more information, see OMSA user’s guide at dell.com/openmanagemanuals. Background initialization Background initialization (BGI) of a redundant virtual disk creates the parity data that allows the virtual disk to maintain its redundant data and survive a physical disk failure. -
Page 16: Virtual Disk Cache Policies
Virtual disk cache policies NOTE: Configuring virtual disk cache policies on NVMe PCIe SSD is not supported. The PERC S140 uses part of system memory for cache. It supports the following cache options: • Read Ahead/Write Back • No Read Ahead/Write Back •... -
Page 17: Expanding Virtual Disk Capacity
If the target system was turned off, turn on the system. CAUTION: The BIOS Configuration Utility pauses, and prompts for action, for the degraded virtual disk(s), if the "pause if degraded" option is enabled in the BIOS Configuration Utility. CAUTION: After the migration occurs, ensure that all of the physical disks have been migrated and are present in the appropriate virtual disks. -
Page 18: Cabling The Drives For S140
Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that are shipped with your product. -
Page 19: Disk Connectivity For Ahci Devices
The S140 controller supports systems with up to two AHCI devices. For systems with two AHCI devices, the first AHCI device connects the drives from ports 0–5 and the second AHCI device connects the drives from ports 6–13. The following table provides information about the disks connectivity to the AHCI devices supported on the 14th generation PowerEdge systems. -
Page 20: Bios Configuration Utility
BIOS Configuration Utility The BIOS Configuration Utility, also known as Ctrl+R or Option ROM (OPROM), is a storage management application integrated into the System BIOS accessible using F2 during system boot, which configures and maintains RAID disk groups and virtual disks on SATA drives. The BIOS Configuration Utility (Ctrl+R) is independent of the operating system. -

Page 24: Assigning The Dedicated Hot Spare Disks
Assigning the dedicated hot spare disks A dedicated hot spare is a backup physical disk for the redundant virtual disk to which it is assigned. The physical disk that is used as a dedicated hot spare cannot be a member of an existing virtual disk. When the hot spare is activated, it becomes the receptacle for the data from the failed physical disk member of the volume, without interrupting the system or requiring your intervention. -
