Hi community,

we’re designing our first Ceph cluster here and we’re struggeling with the MON (and also MDS) nodes RAM recommendations. It sais „like 1GB per daemon instance“, but what daemons are meant here? The range is from per MON (MDS) daemon, which would be fairly low, to per OSD daemon, which would be fairly high. Any help would be appreciated.

Kind regards

Sebastian
