I.e. you can connect your Ceph nodes on L2 or make them part of the L3 setup (more modern way of doing it). You can use "ECMP" to add more network capacity when you need it. Setting up a BGP EVPN VXLAN network is not trivial ... I advise on getting networking expertise in your team. Radha: Thanks for the reference. We are planning to have a dedicated set of nodes, for our ceph cluster and not make it hyperconverged. Do you see that as a recommended option ? Since we might also have baremetal servers for workloads, we want to make the storage as a separate dedicated one. Gr.
