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 pre-conditioned and/or BIOS settings are not

optimal.

Solution

•

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.

Without pre-conditioning the NVMe PCIe SSD, performance measurements can

be misleading as they may not reflect long term performance of the device.

Pre-conditioning activates flash management, which stabilizes data throughput

over a period of time. For the Solid State Storage Performance Test

Specification, refer to snia.org.

Configure the server for low latency performance. To achieve maximum

performance with Dell PowerEdge Express Flash NVMe PCIe SSDs, change the

server performance profile in the BIOS settings to Performance.
