Ensure you have the appropriate NVMe RAID FoD license, as only Intel-branded NVMe SSDs are supported for RAID configurations. Additionally, verify that you are using Lenovo-qualified NVMe drives for compatibility and consider updating your firmware with the latest Lenovo Bootable Media Creator ISO. [community thread]
First, verify that the NVMe drives in the affected bays are properly seated and connected. Restarting the XClarity Controller (XCC) may also help restore the drive inventory. Additionally, ensure that your server's firmware is up to date and check the VMD settings in the BIOS/UEFI for correct configuration. [community thread]
If you're experiencing low write speeds of 15-20 MBps, this may be expected due to the cacheless nature of the 5350 controller, which operates in write-through mode. To potentially improve performance, you can enable the drive cache using the MegaRAID BIOS interface or storcli commands. For significant speed enhancements, consider upgrading to a controller with a cache module. [community thread]
Yes, the ThinkSystem SR650 V3 server supports upgrading to an NVMe backplane, allowing for the use of NVMe SSDs and M.2 drives with the appropriate adapter. Ensure that the backplane is specifically designed for this model and that all firmware and drivers are current for optimal performance. [community thread]
To resolve this issue, check the BIOS settings to ensure the m.2 NVMe drive is set as the primary boot device and that the boot mode for the RAID controller is configured to UEFI. Additionally, update the firmware and drivers for the RAID controller and verify the RAID configuration to ensure it does not conflict with the boot drive settings. [community thread]
