Overview

The Dell PowerEdge Express Flash Non-Volatile Memory Express (NVMe) Peripheral Component
Interconnect Express (PCIe) Solid State Device (SSD) Adapter is a high performance storage device
designed for solutions requiring low latency, high I/O operations per second (IOPS), and enterprise class
storage reliability and serviceability. The Dell NVMe PCIe SSD is offered as a MultiLevel Cell (MLC) NAND
flash technology with a high-speed PCIe 3.0 compliant interface. The high-speed PCIe 3.0 compliant
interface helps improve performance for I/O bound solutions.
NVMe is the standardized, high performance host controller interface that uses solid-state devices on a
PCI Express bus (PCIe SSDs). Dell NVMe PCIe SSDs comply with the NVMe 1.0 specification.
Dell NVMe PCIe SSD SM1715 family of adapters is available in 1.6 TB and 3.2 TB capacities and supported
on selected Dell PowerEdge systems.
PCIe interface
The SSD controller used on the Dell NVMe PCIe SSD has a PCIe Generation 3 (8 GT/s) interface. The
interface is a PCIe x4 lane width for a 16-channel flash memory controller. The PCIe interface is used to
transmit or receive storage interface commands between the host and the NVMe PCIe SSD.
NVMe PCIe SSD adapter features
The following sections describe the different features of the Dell NVMe PCIe SSD Adapter.
Device health
The Dell NVMe PCIe SSD design is based on MLC NAND flash technology. NAND SSDs have a finite
number of program or erase cycles and a finite number of spare blocks (replacements for other worn or
faulty NAND blocks).
The program erase cycles and spare blocks are continuously monitored for each Dell NVMe PCIe SSD
through various Dell software management applications. For more information see Configuring and
managing your NVMe PCIe SSD adapter.
Self-Monitoring Analysis and Reporting Technology
The Self-Monitoring Analysis and Reporting Technology (SMART) feature-set minimizes unscheduled
system downtimes by providing a method of early detection of device degradation or fault. By monitoring
and storing critical performance and calibration parameters, the SMART feature set attempts to predict
degradation or fault conditions. Awareness of a negative reliability condition allows the host system to
warn you of an impending risk of device failure and advise on appropriate action.
5
Remaining rated write endurance
NAND SSDs have a finite number of program erase cycles. The Dell NVMe PCIe SSD is warranted to a
maximum amount of data written to the device in total bytes written. The NVMe PCIe SSD self monitors
for these limits, and Dell software management applications notify you when you reach these limits.
NOTE: If you continue to write to the device after it reaches the threshold of total bytes written, the
amount of time the Dell NVMe PCIe SSD retains data while powered off decreases below device
specifications. For more information see Technical specifications.
Device write status
NAND SSDs have a finite number of spare sectors. If the device exhausts the available spare sectors, the
Dell NVMe PCIe SSD enters Write Protect (Read-Only) mode. In Write Protect mode, you can only
perform read operations to the device. The Dell NVMe PCIe SSD self monitors for these limits, and Dell
software management applications notify you.
Supported operating systems for the NVMe PCIe SSD
Only the following operating systems support Dell NVMe PCIe SSD devices:
•
Microsoft Windows Server 2008 R2 SP1 (x64/EM64T) or later
•

Configuring the NVMe PCIe SSD adapter in different
operating systems
In Windows-based systems, Dell NVMe PCIe SSDs have a controller entity and a device entity. The
controller entity is displayed under the Storage controller menu in the Device Manager.
Use the controller entity when installing or updating the NVMe PCIe SSD driver. You can configure the
NVMe PCIe SSD for use on Windows from, Computer Management → Storage → Disk Management
Tool.
On Linux-based systems, you can configure the NVMe PCIe SSD from the partitioning tool by specifying
or selecting the device name. The device name for NVMe PCIe SSDs is /dev/nvmeXn1, where X is the
number corresponding to each NVMe PCIe SSD in the system (For example: /dev/nvme0n1; /dev/
nvme1n1; /dev/nvme2n1 and so on).
Use OpenManage Server Administrator for managing and performing NVMe PCIe SSD-related tasks. For
more information, see Configuring and managing your NVMe PCIe SSD adapter.
In VMware systems, you can configure the NVMe PCIe SSD as datastore or for a passthrough operation.
You can use vSphere Client to configure the NVMe PCIe SSD. Configuring NVMe PCIe devices as
passthrough has the following limitations:
•
You cannot take snapshots of the Virtual Machine (VM).
•
Your VM cannot use failover features such as VMotion and Distributed Resources Scheduler (DRS).

Self-Monitoring Analysis and Reporting Technology
errors
The NVMe PCIe SSD solution is always monitored for errors by its internal software. If an error occurs, it is
detected and recorded in an internal log. Based on the criticality of the error, the software may inform the
host server that further action is needed. It signifies that the error condition occurred a specific number
of times and that the device health needs attention.
Ungraceful system shutdown or power loss
If the host system experiences a power loss, the NVMe PCIe SSD may not have time to perform its
internal shut down procedure. In such an event, the device may enter a recovery mode.
This recovery process is also known as rebuilding. During rebuilding, there is very limited access from the
host operating system. After the recovery procedure is complete, the device is fully accessible from the
host operating system.
NOTE: Dell recommends that you use power backup solutions for all Dell systems.
General errors
The following section describes general errors related to NVMe PCIe SSD.
NVMe PCIe SSD description is truncated
Description
In Windows 2012 R2, the device description is truncated from the Device Manager
→ Disk Drives view. For example, you see NVMe Dell Express Flash or NVMe Dell
Express Fla SCSI Disk Device instead of NVMe Dell Express Flash SCSI Disk Device.
Cause
In Windows 2012 R2, there is a new flag
STOR_FEATURE_DEVICE_NAME_NO_SUFFIX that removes the suffix in the
device friendly name. This is only seen in Windows 2012 R2 and this flag is enabled
by design of the Windows 2012 R2 in-box driver. The Dell-provided NVMe driver
uses the correct flag, but you may see the device name truncated intermittently.
Solution
This is a known issue and the message can be ignored.
21
Software RAID array created by using PCIe SSDs is not detected after SLES 11
is rebooted
Cause
The boot.md service is not started during RAID creation. The boot.md service must
be enabled for the init process to start the MD-RAID device.
Solution
Run the command # chkconfig boot.md to verify if the boot.md service is on
or off. This command should start the boot.md service. If it does not, run the
command# chkconfig boot.md on to enable it.
NVMe PCIe SSD is not displayed in device management in operating system
Cause
The device driver is not installed.
Solution
See Driver installation.
Cannot update firmware by using Dell Update Package (DUP)
Cause
The device driver is not installed.
Solution
Before you update the device firmware using DUP, install the device driver. For
more information, see Driver installation.
Linux fails to boot and prompts for the root password
Cause
A stale volume mount point is still present after a device removal or cryptographic
erase.
Solution
Perform the following steps to recover from this situation:
1.
Enter the root password to enter maintenance mode.
2.
Remount the root filesystem as read-write using the following command:
mount -orw,remount/.
3.
Manually edit /etc/fstab to remove the nonexistent device entry.
I/O device error on write to NVMe PCIe SSD
Description
Windows event log may report the following entries on the first write attempt to an
NVMe PCIe SSD: Event ID 7: The device, \Device\Harddisk\DRX, has
a bad block.
When attempting to initialize the device using Computer Management → Storage
→ Disk Management, the following message is displayed: Virtual Disk
Manager, Data Error (cyclic redundancy check).
Linux messages log may report the following entries on a write attempt to an
NVMe PCIe SSD:
22
•
Buffer I/O error on device nvmeXn1, logical block Y (where X
is the number corresponding to the device and Y is the
logical block)
•
nvmeXn1: unable to read partition table (where X is the
number corresponding to the device)
Cause
NVMe PCIe SSDs have a finite number of write cycles. When an NVMe PCIe SSD
exhausts the number of writes, it goes into Write Protect (Read Only) mode.
Solution
By using Dell system management applications, you may check the NVMe PCIe
SSD state to confirm if the NVMe PCIe SSD is in Read-Only Mode. For further
instructions, contact a Dell Technical Service representative.
NVMe PCIe SSD performance measurement not optimal
Description
There are a number of factors that may alter the performance of an NVMe PCIe
SSD. It is recommended to take basic setup measures to ensure performance
optimization of these devices.
Cause
NVMe PCIe SSD has not been preconditioned and/or BIOS settings are not optimal.
Solution
•
Without preconditioning the NVMe PCIe SSD, performance measurements can
be misleading as they may not reflect long-term performance of the device.
Preconditioning enables flash management, which stabilizes data throughput
over a period. For the Solid-State Storage Performance Test Specification, see
snia.org.
•
Configure the server for low latency performance. To achieve maximum
performance with Dell NVMe PCIe SSDs, change the server performance profile
in the BIOS settings to Performance.
In Windows Server 2012 R2, OpenManage Server Administrator does not
detect PCIe NVMe devices
Description
Windows Server 2012 R2 contains an in-box NVMe driver, which is not supported
by Dell OpenManage Server Administrator.
Cause
The operating system is using the in-box NVMe driver.
Solution
Install the latest NVMe driver available on dell.com/support.
Windows event ID 11 error reported in Windows event log
Description
Event ID 11 Error is reported in the Windows event log during each system boot.
Cause
This issue exists in the in-box Windows NVMe driver.
Solution
Install the latest NVMe driver available on dell.com/support.
