Ceph nodes and non-ceph nodes

[Zombie]

I might have missed the mark, but I have a simple question to see if Im correct or if I need to get a few more parts.

Currently I have a three node ceph cluster that was deployed through the proxmox gui. I have 2 x 10 Gb ports, one for public and other for private ceph traffic. Then I have 2 x 1GB ports. I one of the 1Gb ports is used only for the corosync traffic. I am looking at adding a 4th node to the cluster only for compute power. It has 4 x 1 Gb ports. One of those ports will be for the corosync traffic. My questions is when I create a VM on the this node using the ceph storage in this cluster does this node also need the10Gb ports? This node will not have any OSD's, it is only for VM compute power?

Thanks for any hints or help to help get me right.

no, you can use gigabit link if you want, no problem. (your vms on this host will be limited to 1gbit/s for read/write)
