Hello Eugen We planned to start with a small cluster with HDD disks and a Replicas of 2 . it will be consist of 6 hosts , 3 of them are MONS which will hold also 2 MGRs and remaining 3 are for OSDs . and will use VM for deployment . one of the OSD host will be used also as RGW client for Object storage, and failure domain will be based on hosts. your inputs are highly appreciated.
