My Ceph cluster at home isn't designed for performance. It's not designed to maximum availability. It's designed for a low cost per TiB while still maintaining usability and decent disk-level redundancy. Here is some recent tuning to help with performance and corruption prevention....
Previously I posted about the used 60-bay DAS units I recently acquired and racked. Since then I've figured out the basics of using them and have them up and working.
[ceph: root@xxxxxx0 /]# ceph orch host add xxxxxxxxxxx1
