Ceph on a storage server


Aug 22, 2020

I want to do this installation:
3 nodes (2 ssd in mirror only for proxmox boot)
1 storage with 20 disks (14 TB storage)
All connected in fiber channel 10Gb

I want to have snapshot, thin provisioning and all this features, so I want to use Ceph.

Is possible to install ceph on the storage server and run it only on this?
I know that the best practice is to use minimun 3 nodes, but I think this 3 nodes is supposed to have disks, attached like storage and so on.

In this case all the storage is on one server.

Is possible to do that? And if yes, what I have to install on the storage? A Ubuntu and then install the Ceph?
