Hello , non and osd. 1 small ssd is for operations system and 1 is for mon. I am agree to increase the ram. As far as nvme size it is true that more osd little disks is a better choose for performances but I should buy more servers.

Hello, what do you think about of ceph cluster made up of 6 nodes each one with the following configuration ?
I forgot to ask: Are you planning on only OSDs or should this be OSDs and MONs and ?
In case of MONs / OSDs: give the MON a dedicated NVMe / SSD drive (not to small, in case cluster gets degraded it needs to store pglog info and storage usage will grow. Go for monstore that can hold like 800 GB or so). You want definitely want to add more memory to give MON / MGR enough.
Want to add MDS?: add plenty of RAM (more is better).
