Hello Mevludin Blazevic, Yes it is quite possible, I did it on my cluster. I put the cephDB (WAL + RocksDB) hard drives on the SSD drives. That increases the performance of HDD.

Dear Ceph users, I have a small Ceph cluster where each host consist of a small amount of SSDs and a larger number of HDDs. Is there a way to use the SSDs as performance optimization such as putting OSD Journals to the SSDs and/or using SSDs for caching? Best regards, Mevludin -- Mevludin Blazevic, M.Sc.
