The main problem we've observed is that not all HBAs can just
efficiently and easily pass through disks 1:1. Some of those from a
more traditional server background insist on having some form of
mapping via RAID.
In that case it depends on whether 1 disk unit RAID0s or "JBOD"
passthrough is more efficient, that's also hardware specific.
As a general best practice, that'd be to just give Ceph OSDs the disks
as they are.
