Front-Loading NVME SSD Requirements and Restrictions
Observe these requirements:
• The server must have two CPUs. PCIe riser 2 is not available in a single-CPU system. PCIe riser 2 has
• PCIe cable CBL-NVME-C220FF. This is the cable that carries the PCIe signal from the front-panel drive
• Hot-plug support must be enabled in the system BIOS. If you ordered the system with NVMe drives,
Observe these restrictions:
• NVMe SFF 2.5- and 3.5-inch SSDs support booting only in UEFI mode. Legacy boot is not supported.
• You cannot control NVMe PCIe SSDs with a SAS RAID controller because NVMe SSDs interface with
• UEFI boot is supported in all supported operating systems. Hot-insertion and hot-removal are supported
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 PCIe SSDs, the setting was enabled at the factory. No action is
• If you are adding NVMe PCIe SSDs after-factory, you must enable hot-plug support in the BIOS. See
