Hi Mads, Imo, if you want that flexibility you should go with non-local storage. CEPH is a popular choice here, but you will need 10 Gbps between hypervisors and storage servers if you want reasonable performance. So, if you need more storage just add more CEPH servers. Need more compute, add more hypervisors.
