[ceph-users] Single disk per OSD ?

Hi all, 

I believe most exiting setups use 1 disk per OSD. Is this going to be
the most common setup in the future ? With the move to lvm, will this
prefer the use of multiple disks per OSD ? On the other side i also see
nvme vendors recommending multiple OSDs ( 2,4 ) per disk as disks are
getting faster for a single OSD process. 

Can anyone shed some light/recommendations into this please ? 

Thanks a lot.
