[ovirt-users] Network/Storage design

Hi, I am new to oVirt and trying to deploy a cluster to see whether we can move from VMWare to oVirt, but my first stopper is how to do a proper design for the infrastructure, how many networks do I need?, I have 2x10Gb SFP+ and 4x1Gb ethernet. For storage we have NFS coming from Netapp and ceph. Could someone point me in the right direction? Thanks.
