I have Dell EMC SCv3020 Storage Array and I want to create shared storage for all 3 physical servers to use the same (LVM?) for creating KVM VMs in cluster so if 1 server dies, we can move VM to another one. We have solution for HA failover but we are not sure how to do this shared storage setup.

We also have VMware on this infrastructure using Dell storage array and production VMs on it so is it possible maybe to use VMFS vmware datastore to create like 4 VMs for Ceph and assign for example 1 TB of storage to each Ceph OSD and this way we use this shared storage on all 3 new physical servers for deploying KVM VMs all servers on same shared storage?

What are you suggesting? Thank you for your help and advices!
