Not sure if we can't really tell apart SSDs from NVMe devices, but you
can use the --crush-de
Hi,
Can you benchmark your Optane 900P with `fio -fsync=1 -direct=1 -bs=4k
-rw=randwrite -runtime=60`?
It's really interesting to see how much iops it will provide for ceph :)

Dear All,
Not sure if this is a bug, but when I add Intel Optane 900P drives,
their device class is automatically set to SSD rather than NVME.
This happens under Mimic 13.2.0 and 13.2.1
