Hi Tino, Proxmox has a good wiki for this: https://pve.proxmox.com/wiki/Deploy_Hyper-Converged_Ceph_Cluster You will run their internal deployment process, which is easy and painless. I recommend starting with 3x replication, and setting up your NVMe root with either UI or scripts. Here is an example command we used to create OSDs on all 20TB drives on a given Proxmox VE host: lsblk|grep 18.2|grep disk|awk '{print $1}'|xargs -I {} pveceph osd create /dev/{} --encrypted 1 --crush-device-class hdd -db_dev /dev/nvme0n1 --db_dev_size 300 -- Alex Gorbachev ISS/Storcium www.iss-integration.com On Wed, Mar 29, 2023 at 9:47 AM Tino Todino <tinot@xxxxxxxxxxxxxxxxx> wrote: > 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.
