Mega-core server does not support NVMe
1
Because the only physical interface SATA and PCIE M2 in the three
but NVME only supports these two PCIE M2 and
2
so NVME does not support SATA port, so no NVME SATA cable. Because NVME SSD is plugged directly into the physical M2 and two types of hardware PCIE socket. M2 and these two PCIE socket inside only in the server. You must remove the cover to see.

So NVME is onboard PCIE SSD otherwise it is inserted in the socket.
4 Check the command lspci | grep Non-Volatile
Expected results:
# lspci | grep Non-Volatile
0A: 00.0 Non-Volatile Memory the Controller: Samsung Electronics Co Ltd A808 Device
Support NVME
# lspci |grep Non-Volatile -i
03:00.0 Non-Volatile memory controller: Toshiba America Info Systems Device 011a
5 by command to check # ll / dev / n * | grep nvme
Expected result:
Support NVME
# ll /dev/n* |grep nvme
