Building a ceph cluster

[bangbang]

Hi,
I currently have a cluster of three identical elitedesk g4 sff.

Each pc has:
CPU: i5-8500
RAM: 32GB
256GB ssd from proxmox
1TB ssd on vms and lxcs
2x nic: 1GbE on board, 10GbE PCIe

I want to build a ceph cluster from this.
I replaced the 1TB SSD drive with a 1TB nvme so that the vms would run fast.

I'm wondering if I should also replace the 256GB ssd drive with an nvme drive or if it doesn't make sense since I only want to have Proxmox on it.


The network card has one 10Gbps sfp+ port.
This card will support the public network and the cluster network.
I will use the 1Gbps card for Proxmox and vms to have internet access.

Do you have a specific reason for choosing that technology? Is it for learning or do you expect to get a robust, stable cluster for productive use?

Ceph is great if you have several nodes and several OSDs per node. Some pitfalls: https://forum.proxmox.com/threads/fabu-can-i-use-ceph-in-a-_very_-small-cluster.159671/

For now I just want to see how ceph works in a three node cluster.

If everything is ok I would like to create a five node ceph cluster and each of them would have two OSDs
