how many nodes do you reccomend for a Proxmox Cluster with Ceph (HCI mode)? We would like to start with 4 node with 6 SSD disk each, so will have 6 OSD per node and PVE OS on SATA Dom.

The other option is 8 node with the same 6 SSD disk on each.

Is fine to start with 4 node? Somebody suggest me to not use 4 node for possible quorum problems.

Thanks
