• NVMe SSDs support booting only in UEFI mode. Legacy boot is not supported.
• UEFI boot is supported in all supported operating systems. Hot-insertion and hot-removal are supported
in all supported operating systems except VMWare ESXi.
• You cannot control NVMe SSDs with a SAS RAID controller because NVMe SSDs interface with the
server via the PCIe bus.
Enabling Hot-Plug Support in the System BIOS
Hot-plug (OS-informed hot-insertion and hot-removal) is disabled in the system BIOS by default.
• If the system was ordered with NVMe SSDs, the setting was enabled at the factory. No action is required.
• If you are adding NVMe SSDs after-factory, you must enable hot-plug support in the BIOS. See the
following procedures.
Enabling Hot-Plug Support Using the BIOS Setup Utility
Step 1
Enter the BIOS setup utility by pressing the
F2
key when prompted during bootup.
Step 2
Navigate to
Advanced > PCI Subsystem Settings > NVMe SSD Hot-Plug Support
.
Step 3
Set the value to
Enabled
.
Step 4
Save your changes and exit the utility.
Enabling Hot-Plug Support Using the Cisco IMC GUI
Step 1
Use a browser to log in to the Cisco IMC GUI for the server.
Step 2
Navigate to
Compute > BIOS > Advanced > PCI Configuration
.
Step 3
Set NVME SSD Hot-Plug Support to
Enabled
.
Step 4
Save your changes.
Replacing a Front-Loading NVMe SSD
This topic describes how to replace 2.5-inch NVMe SSDs in the front-panel drive bays.
OS-surprise removal is not supported. OS-informed hot-insertion and hot-removal are supported on all
supported operating systems except VMware ESXi.
Note
OS-informed hot-insertion and hot-removal must be enabled in the system BIOS. See
Support in the System BIOS, on page 18
