I think PGs have more to do with this, the docs were pretty good at explaining it.  Hope this helps

Hi all,  we’re new to CEPH.  We’ve some old machines redeployed for setting up CEPH cluster for our testing environment.

There are over 100 disks for OSDs.   Will use replication with 2 copies.   We wonder if it’s better to create pools on all OSDs, or using some OSDs for particular pools, for better performance and reliability ?     Thanks a lot.
