[ceph-users] ceph nvme 2x replication

Hi all, I have noticed that RedHat is willing to support 2x replication with NVME drives. Additionally, I have seen CERN presentation where they use a 2x replication with NVME for a hyperconverged/HPC/CephFS solution. I would like to hear some opinions on whether this is really a good idea for production. Is this setup (NVME/2x replication) really only meant to be used for data that is backed up and/or can be lost without causing a catastrophe. Thanks, Frank
