Thinking of trying ceph

I have 3 kvm nodes 2 of them have 6 bays and lsi card for storage that just sitting there because for now my VM sit on a NAS shared by NFS. Can I install ceph on those 2 nodes to make it a datastore? If so what would I need to make it so. both those nodes have two 16 core processors a piece and have room for two more.
Thanks
