Currently indeed each datacenter must be configured as a shared or local storage one, no mix for the same datacenter. For the next release (ovirt 3.6) we are going to have oVirt and GlusterFS hyper converged: you'll can use each host both for virtualization pourposes and for storages ones sharing the local spare disks into a shared GlusterFS volume to be used by oVirt hosts. So you can also have HA capabilities and so on for the VM stored on the host disks shared in a GlusterFS volume; at the same time you could still use you state-of-the art SAN for critical VMs. Here you can find some info an this architecture: http://www.ovirt.org/images/6/6c/2015-ovirt-glusterfs-hyperconvergence.pdf Than we are also going to have self-hosted engine over GlusterFS. > Pat > > [1] http://www.ovirt.org/OVirt_Administration_Guide#Preparing_Local_Storage
