Hello, i'm plannung to split the block db to a seperate flash device which i also would like to use as an OSD for erasure coding metadata for rbd devices. If i want to use 14x 14TB HDDs per Node https://docs.ceph.com/docs/master/rados/configuration/bluestore-config-ref/#sizing recommends a minimum size of 140GB per 14TB HDD. Is there any recommandation of how many osds a single flash device can serve? The optane ones can do 2000MB/s write + 500.000 iop/s.
