The general recommendation is to target around 100 PG/OSD. Have you tried the https://ceph.com/pgcalc/ tool?

_______________________________________________Hi Everyone,I would like to know what kind of setup had the Ceph community been using for their Openstack's Ceph configuration when it comes to number of Pools & OSDs and their PGs.Ceph documentation briefly mentions it for small cluster size, and I would like to know from your experience, how much PGs have you created for your openstack pools in reality for a ceph cluster ranging from 1-2 PB capacity or 400-600 number of OSDs that performs well without issues.Hope to hear from you!Thanks.Regards,
Ossi
