My $0.02: We use DELL r740xd with NVMe and FreeBSD 13.0-STABLE (with =
some NFS patches from Rick Macklem, that are
now included in releng/13) and ZFS.

NVMe disks are of Dell (type Dell Express Flash PM1725b 1.6TB SFF =
1.2.2).

So far we haven=E2=80=99d experienced any issues with them, neither with =
the server as such.
The only change from the =E2=80=9Cstock=E2=80=9D state of the HW was =
that we replaced Broadcom bnxt(4) NIC with Intel ix(4) NIC.

The server provides NFS shares for OpenStack compute nodes.
