Yes stand-alone OSDs (WAL/DB/Data all on the same disk), this is the same as it was for Jewel / filestore. Even if they are consumer SSDs why would they be 40% faster with an older version of Ceph?

Standalone OSDs? Or do they have their WAL/DB partitions on another device? How does it compare to your Filestore setup for the journal? On a separate note, these look like they're consumer SSDs, which makes them not a great fit for Ceph.

Could you please share the current performance. How many OSD nodes do you have?

Any thoughts on what I may need to do with Ceph to speed things up? I have 30 SSDs backing an 11 compute node cluster.
