[ceph-users] palcing SSDs and SATAs in same hosts

Hi, I am thinking how to make ceph with 2 pools - fast and slow. Plan is to use SSDs and SATAs(or SAS) in the same hosts and define pools that use fast and slow disks accordingly. Later it would be easy to grow either pool by need. I found example for CRUSH map that does similar thing by
