Table 2. SATA Specifications for PERC S140SATA Drive Specifications
Specification PERC S140
Dell-compliant SATA compatibility Yes
Communication with the end devices SATA links
SATA connectors Discrete on the system board
I/O controller Intel C621 (C620 series chipset) (onboard SATA) and Advanced Micro Devices (AMD)
Communication with the system Integrated
Software-based RAID for SATA drives Windows RAID: Volume, RAID 1, RAID 0, RAID 5, RAID 10
Linux RAID: RAID 1
NOTE:Non-boot virtual disks of any supported RAID level by the Linux OS installed on RAID-1 disk can also be created using native Linux RAID utilities.
Pass through SSD support Yes
Table 3. NVMe Specifications for PERC S140NVMe Device Specifications
Specification PERC S140
On systems running Windows, if there is no NSID=1 present on the NVMe drive, the drive is not accessible and is marked offline. Firmware upgrades run on the NVMe drive are successful, however.
Maximum number of namespace(s) supported 1
NOTE:If the drive having more than one namespace(s) is connected, the drive is marked offline and is inaccessible.
NVMe connectors PCIe/slimline
NOTE:Only Dell-compliant NVMe PCIe SSD 2.5 inch Small Form Factor (SFF), or NVMe PCIe SSD Adapters are supported.
Dell-compliant NVMe compatibility Yes
Communication with end devices PCIe
Software-based RAID for NVMe PCIe SSDs Windows RAID: Volume, RAID 1, RAID 0, RAID 5, RAID 10
Linux RAID: RAID 1
NOTE:Non-boot virtual disks of any supported RAID level by the Linux OS installed on RAID-1 disk can also be created using native Linux RAID utilities.
Pass through NVMe PCIe SSD support Yes

The following table provides PERC S140 virtual disk specifications:

Table 4. Virtual disk specifications for PERC S140 with SATA configurationVirtual disk specifications for PERC S140
Specification PERC S140
Maximum number of physical disks supported 12
Maximum number of virtual disks supported 30
NOTE:Maximum number of virtual disks may exceed 30 when:
  • physical disks are migrated from any other configuration
  • a disk in Ready state is converted to a non-RAID disk
Maximum number of virtual disks supported from a single disk group 8
NOTE:Maximum number of virtual disks can exceed more than 8 from a single disk group as there is no constraint from PERC S140.
Minimum virtual disk (VD) size 10 GB
NOTE: PERC S140 does not restrict the creation of VDs of size less than 10 GB.
Maximum number of physical disks per virtual disk 8
NOTE: PERC S140 does not restrict the creation of VDs using more than 8 physical disks.
Maximum number of virtual disks per physical disk 8
Maximum number of physical disks in a volume 1
Maximum number of physical disks in a RAID 0 8
Maximum number of physical disks in a RAID 1 2
Maximum number of physical disks in a RAID 5 8
