Peter; I was just looking at this myself. With regards to BlueStore, the Config Reference is useful: http://docs.ceph.com/docs/master/rados/configuration/bluestore-config-ref/ As far as tiering goes, the OSD Config Reference talks about it: http://docs.ceph.com/docs/master/rados/configuration/osd-config-ref/ The following talks extensively about tiering, and recommends not doing it: http://docs.ceph.com/docs/master/rados/operations/cache-tiering/ Thank you, Dominic L.

My Setup should be: 3 Nodes Cluster, on each with: - Intel Gold Processor SP 5118, 12 core / 2.30Ghz - 64GB RAM - 6 x 7,2k, 4 TB SAS - 2 x SSDs, 480GB On the POSIX FS you have to set your journal on SSDs. What is the best way for bluestore? Should I configure separate SSDs for block.db and block.wal? Is there a way to use CacheTiering or a cachepool?
