Hi folks. Just looking for some up to date advice please from the collective on how best to set up CEPH on 5 Proxmox hosts each configured with the following: AMD Ryzen 7 5800X CPU 64GB RAM 2x SSD (as ZFS boot disk for Proxmox) 1x 500GB NVMe for DB/WAL 1x 1TB NVMe as an OSD 1x 16TB SATA HDD as an OSD 2x 10GB NIC (One for Public and one for Cluster networks) 1 GB NIC for management interface The CEPH solution will be used primarily for storage of another Proxmox cluster's virtual machines and their data. We'd like a fast pool using the NVMe's for critical VMs and a slower HDD based pool for VM's that don't require such fast disk access and perhaps require more storage capacity. To expand in the future we will probably add more hosts in the same sort of configuration and/or replace NVMe/HDDs OSDs with more capacious ones. Ideas for configuration welcome please.
