What Robert wote, plus: IMO the important thing here is "at the same time or not" and "1000 times redundant"? The second one is easy, it does not make sense. For the first one: Usually you make resource available 2 or 3 times redundant (every bit is also on 1 or 2 different servers). And then you have like a ton of hypervisors. But only one connects to the storrage at a given point in time. Or 2 because of live migration. These hypervisors would be diskless clients, that connect to the storage via network only. And if they don't need it anymore, another diskless client accesses the data. Most of our plugins that integrate DRBD/LINSTOR with other platforms like k8s, openstack, opennebula,... do exactly that: They create storage N-times redundant and create/delete diskless assignments on demand. So yes, conceptually you then can have 1000 nodes.
