Hi all,
Currently, I have the following setup:
I run a pve cluster with 3 nodes. Each node has two gigabit network interfaces one with a public management IP and one on an internal switch with a private IP.
Now, since the public IPs are not on the same network, I created the cluster using the private IPs. The internal network is also used to mount NFS shares.
Thus far everything works really well.
Now, what I would like to know is if it makes sense to setup ceph on the three nodes:
Thanks a lot,
Martin

Now, what I would like to know is if it makes sense to setup ceph on the three nodes:
- Given the fact that it is 'only' gigabit ethernet, what will performance be like?
- Even if it is (which I anticipate) too slow for running VM images, would it be suitable for backup purposes?
- Do I need a separate (e.g. VLAN) network on top of the existing private LAN?
- Are there any other caveats I need to watch out for?
Thanks a lot,
Martin
